Swimming Pool Pumps: Choosing The Right One For Your Pool

Sta-rite pool pumps It’s important to ensure you choose the right swimming pool pump when planning your pool, or when replacing an existing pump.

What does a swimming pool pump do?

UK guidelines for residential pools state that the entire volume of pool water should pass through the filtration system every 8 hours.  The pool pump controls the circulation system of the pool water, a very important job as the circulation and filtration of the pool water ensures your chemicals are properly distributed, preventing the water from stagnating. 

The pool pump draws the water through the skimmer and the main drain, forces it through the filter (which traps and removes debris and impurities) then returns it back to the pool via the return inlet.   

How do I find the correct size pump?

The first thing to establish when choosing a pool pump is:

  • The total volume of water in your swimming pool(in gallons). This can be calculated using the following formula:

Calculating the volume of your pool Astral Victoria Plus pool pumps

Square & Rectangular Pools

Length (ft) x Width (ft) x Average Depth (ft) x 6.25 = Gallons

Circular Pools

Diameter (ft) x Diameter (ft) x Depth (ft) x 4.9 = Gallons

The water flow rate (gallons per minute) of a pool pump determines how quickly the pump can move the water.  We can use the below example;

Pool Volume = 24,000 gallons of water

  • To calculate how many gallons you need to pump each hour based on an 8 hour total turnover, divide the number of gallons by 8 (24,000  8 = 3,000)
  • Divide the 3,000 by the number of minutes per hour (60) then = 50 gallons per minute, in order to provide a complete turnover of the pool water in 8 hours.

Fitting An Endless Pools Fastlane To Your Swimming Pool

So what exactly is the Endless Pools Fastlane?

Endless Pools Fastlane counter current swim systemThe Fastlane is a powerful, counter current system that delivers a smooth, even swim current to your swimming pool. It has a fully adjustable swim pace from zero to a 1 minute 10 second hundred yard pace (1 minute 16 second/100 meters) and allows you to swim in place without the need to turn. It’s perfect for converting any small pool into a home fitness system.

How does the Fastlane work?

The Fastlane consists of two parts, a hydraulic power unit and a swim unit. The 5Hp power unit is usually located remotely with other pool equipment and provides power to the swim unit via two hydraulic hoses, utilising biodegradable vegetable based hydraulic fluid. The swim unit mounts pool side. Inside the swim unit is a special, sealed stainless steel hydraulic motor that turns a custom designed 16” (40cm) propeller. Water entering the base of the unit travels through a unique channelling system that helps straighten the swim current and removes any turbulence from the water before being delivered through the final smoothing grill at the front of the unit.How to position your Endless Pools Fastlane system

How do I use the Fastlane?

Using a Fastlane is incredibly straightforward. Simply position yourself in front of the swim unit so that you can swim into the current and then turn the unit on by pressing the on/off switch button on the remote control fob. Once you are comfortable with the swimming position you can increase or decrease the speed by using the faster and slower buttons on the control fob. Remember, because you are swimming without stopping you will tire 20-30% faster than when swimming laps. To stop swimming simply press the on/off button. If you turn the unit back on, the Fastlane current will return to the last speed programmed into the remote. The Fastlane has a built-in safety timer that will automatically shut off the current after 30 minutes.

Where do I position the Fastlane in my pool?

The Fastlane can be installed in virtually any new or existing in-ground concrete, gunite, masonry, vinyl lined or fibreglass pool together with any above ground pool. Water depth can be as shallow as 35”, generally speaking, if a pool is deep enough to swim in, it’s deep enough for a Fastlane!

There are two different types of fitting systems for a Fastlane, either a deck mount or a wall mount bracket. The deck mount option is suitable for retro fitting a swim unit to an existing pool and a wall mount bracket is used for new pool builds as it is incorporated into the wall structure itself.

The swim unit must be installed no closer than 24” (61cm) from any adjacent pool wall and choosing a location that is at least 12’ (3m 65cm) from an opposing wall (see diagram opposite) will provide you with the ideal swim lane for exercising. Remember, to help ensure a turbulent free swim current it is also key to position the swim unit away from surrounding walls, benches and stairs.

Installing a wall mount Fastlane to your new pool build

The wall mount Fastlane attaches to your pool wall with the use of a special, wall mount bracket that is embedded in the pool wall. The hydraulic hoses and power unit are then hidden in the pool wall under the pool deck area leaving a clean looking installation on your pool. If you are building a new pool or significantly refurbishing an existing pool this option of mounting the Fastlane unit is ideal for you.

The minimum clearance guidelines for this type of installation are outlined below.

Installing a deck mount Fastlane to your existing pool

The deck mount Fastlane can be installed on any existing pool without the need to alter the wall structure. A deck mount hose cover conceals the hydraulic hoses and is secured to the deck area around your pool and you can either run the hoses along the pool deck area itself or through a trench. If you are winterising your pool the deck mount Fastlane allows you to easily remove the unit and store it over winter. The hydraulic fluid that remains in the hoses will not freeze, even in cold climates.

If you choose the deck mount Fastlane option there must be 18” (46cm) of solid decking from the pool water’s edge to the mounting site because the swim unit will need to be bolted to the pool deck. If your pool decking isn’t wide enough a small concrete pad will need to be poured to help secure the mounting bracket. Once installed the deck mount Fastlane unit extends 19” (48cm) into your pool and 18” (46cm) onto the pool deck area.

Planning the equipment placement

In addition to planning for the position of the swim unit you must also plan for the location of the hydraulic power unit. Typically this is placed next to your other pool equipment. It is important that the unit is not subjected to driving rain and it must always be placed on soild ground. The power unit is also air-cooled and must be sited with plenty of ventilation, ideally a minimum of 12” (30cm) air space must be left on all sides. In addition, although frequent access is not required it is important that the power unit is accessible once sited for the purposes of general maintenance.

The dimensions of the power unit are as follows.

Electrical requirements

It is important that the Fastlane installation complies with the National Electric Code Article 680 Swimming Pools and Similar Installations and any other applicable local codes and ordinances. The Fastlane is ETL listed, Ref.#2001770, and CE listed. A licensed electrician can help with this review and must perform all electrical work.

Below are some of the most important considerations.

Ground Fault Circuit Interrupters (GFCI)

All equipment provided by Endless Pools, Inc. and all associated pool equipment must be protected by GFCI.

These GFCI circuits must be tested monthly.

Power Unit Connections

The Fastlane requires a single 30-Amp, 220-Volt GFCI circuit to operate. An electrician must install a disconnect box within 6' of the Power Unit location.


Both the Swim Unit and Power Unit have bonding lugs. Proper bonding with a #8 or larger solid copper wire is required.

In summary, why should you build your own endless pool?

Remember, a swimming pool doesn't have to take up a vast amount of space in your garden. If space is at a premium or you don't want to lose valuable playing space for the kids you can always build your own endless pool. A modest sized, inground swimming pool with an Endless Pools Fastlane will create the perfect swim in place pool without the need for as much space. Instead of having to make turns while you swim, you simply swim against the Fastlane's powerful swim current. Perfect!

Instructions On How To Install A Swimming Pool Liner

Fitting your swimming pool liner underlayWhether you are replacing an existing pool liner or building a new liner swimming pool, once you’ve got your new liner it’s important to follow the right steps to install it.

Pre installation notes:

  • Fitting the coping stones before the liner is recommended to prevent damaging the liner once installed (with the linerlock fitted before the coping stones)
  • Ensure the pool is spotlessly clean before you begin and that all gaskets on the pool fittings are in position
  • A minimum outside air temperature of 10°C is required to install a liner (to ensure the liner material is pliable to stretch it into position for a wrinkle-free fit). Temperatures above 24°C should also be avoided as the material may become overly-flexible and risk stretching out of shape under its own weight.


Fitting your swimming pool linerIf you have chosen to fit a foam or felt underlay, spot the adhesive on the pool walls then fit the underlay in place. No adhesive is needed on the pool floor but cross weave tape is used over the joints.

Step by step guide: Liner instructions, how to put it in:

  1. Carefully unpack the liner whilst in the pool itself and check for the arrow showing the deep end of the pool. Unfold the liner carefully and locate the 4 corners beginning with the shallow end and roll out towards the deep end, unfolding the walls accordingly. Consult the full liner installation instructions before proceeding
  2. The beading on the liner fits into the linerlock that is found at the top of the wall (held in position because of its special shape)
  3. If you have or decide to hire a wet & dry vacuum cleaner with hose attachment, it will make fitting the pool liner much easier; fit the liner in the linerlock all around the pool except for a small section about 12 inches away from the deep end corner. Starting to fill your new swimming pool liner with waterPush the suction hose down between the wall and the liner until it is approximately 1 inch (25mm) from the bottom of the wall. Make sure, if the pipework is not completed, that the ends of the pipe runs are sealed off to prevent loss of vacuum. Seal around the vacuum hose with a wet cloth or tape and the liner will be sucked to the pool walls and floor once the vacuum is switched on. Check the liner is in the correct position and if not, turn the vacuum off, adjust then restart it.
  4. Start filling the pool with water once the liner is correctly positioned, leaving the vacuum running until the water covers the shallow end of the pool by at least 6 inches (150mm). The vacuum can then be removed and the remaining liner bead fitted to the linerlock.
  5. Check the positioning of the liner again at this stage. The liner should be bedded down with equal tightness on all 4 sides of the pool.

Pools with a deep end / main drain fitted

  1. Gradually filling your new swimming pool liner cutting in as the water line reaches fittingsOnce steps 1-5 above are thoroughly checked, fill with water until there is 6-8 inches (150mm – 200mm) in the hopper – it’s recommended you anchor the 2 shallow end corners with sandbags at this stage if you are not using a vacuum.
  2. When the water level in the deep end reaches 1 foot (300mm) the main drain can be cut in.
  3. If the liner is away from the shallow end wall (a small gap at the base of the wall is acceptable; this will be pushed in by the weight of water as the pool fills), free it from the linerlock, get behind the liner and gently pull the liner to the shallow end. The liner can stretch considerably, particularly in hot weather. After gently and firmly stretching the liner, weighted sandbags should again be put in each corner to anchor them as filling with water continues (removing them when there is 6 inches (150mm) of water covering the shallow end).
  4. As the water reaches a level just below each of the pool wall fittings/lights etc; stop and cut them in before continuing with the filling process until the water level reaches the middle of the skimmer mouth.
  5. At first, the liner will probably have several packaging folds and wrinkles. These will disappear on their own if installation is done on a hot day but may need some assistance on colder days. Wait until the wrinkle is covered with 3 inches (75mm) of water then gently pull the material away from the wrinkle – once released the weight of the water will keep the liner in its wrinkle-free position.
  6. As the water rises, the wrinkle release process will need to be repeated as necessary in stages, but taking care and showing patience will result in a perfect liner fit. Note: if the water depth gets to 8 inches (200mm) or more over a fold or wrinkle, there will be too much weight on the liner to straighten it out and the wrinkle will be permanent.

Fitting the liner with a Roman End, Square or Corner Step unit

Step Units:

Enjoying your new DIY liner pool kitThere are different types of step units but all will be supplied with a gasket and faceplate. Remove the screws around the faceplate of the step unit and take off the faceplate leaving the gasket attached to the step unit.

For Roman End or Square steps, a plank of timber or scaffolding board is placed temporarily across the top of the step unit and the liner is fitted as described above.

To prevent the liner sagging at the step unit, it is fixed to the plank with drawing pins. As the level of water reaches the first step, the liner should be firmly located around the pool and the faceplate is then fitted. Screws are inserted through the faceplate, gasket and step unit and progressively tightened in sequence. Firmly secured, the liner can now be cut away from the inside of the faceplate and removed.

Applying tape to the back of the liner and the step unit to seal the gap will improve the performance of the vacuum if used.

Building Your Own Swimming Pool With A DIY Pool Kit

Excavating the ground in preparation for building a DIY poolHas the glorious summer we were lucky enough to enjoy this year left you dreaming of improving your outdoor space? Believe it or not, now is the ideal time to put plans into place for having your own in-ground Swimming Pool or installed by Summer 2019.

What are the options?

The first thing to decide is whether a Concrete Tiled or Vinyl Liner DIY pool suits you best. A liner pool is the cheapest option and can be built to a variety of pool sizes. Standard DIY liner kits include a 30 Thou 0.75mm thick ‘bag type’ vinyl liner, with the other option being a 1.5mm thick specialist ‘On Site’ lining that is also available.

Liner pool installations also have a quicker start to finish time, as they don’t have the same curing and drying time requirements as a Concrete pool. Liners usually have a lifespan of 10-15 years (handy tip: the better you look after the pool water chemistry, the longer your liner will last!) which gives you the chance to change the appearance at the time if you feel like a change.

Liner pools consist of a concrete strip foundation with concrete block walls built up from the floor. The pool walls are rendered and the floor screeded, to provide a completely smooth surface for the liner. The vinyl liner is what acts as the waterproof membrane of a liner pool.

Laying the blockwork for the walls of a DIY poolConcrete pools can be built to any size and shape and consist of a reinforced concrete slab base with starter bars coming out of the floor which sit within the cavity of the concrete block pool walls. Concrete pools require 2 coats of waterproof render over the walls and floor, so that the pool shell itself is fully watertight. The purpose of mosaic tiles is simply aesthetic, as they are not necessary as part of the waterproofing.

It’s easier than you might imagine…

Planning permission is not usually required by the majority of UK local authorities for self-build pools in domestic back gardens (unless installing a pool building or an enclosure is also planned), but it is recommended you check with your local authority in advance. And certainly, the foundation work and rendering of the pool walls is typically within the capabilities of a standard builder.

Step by Step, these are the stages involved in DIY Swimming Pool construction:

  1. Preparing the blockwork wall for rendering your in-ground poolMarking out the pool. Once the pool size has been decided, mark the area out to the given dimensions.
  2. Excavation. Time to dig - A mechanical excavator is by far the quickest and easiest method of carrying out this part of the project!
  3. Foundations & Rendering
    Liner Pools: Lay a concrete strip around the perimeter of the pool, 9 x courses of concrete blocks on flat for the walls (with no wall cavity or reinforced bars required for the floor).
    One coat of render is applied to the walls and screed to the floor then a concrete ringbeam fitted behind the top of the pool wall which is then backfilled. The purpose of the render is to provide a completely smooth surface so it’s important to ensure no stones etc are present in the render as this will be visible once the liner is fitted.
    Concrete pools: A steel mesh reinforced concrete slab forms the foundation with starter bars for the walls. 2 courses of concrete blocks on flat make up the walls with a cavity for the steel reinforcement for stability.
    Concrete pools are made watertight by 2 x coats of sand and cement render mixed with a special chemical that provides the waterproofing element.
  4. Installing the underlay prior to fitting the DIY pool kit linerFinishing. A white plastic called ‘Linerlock’ is fitted around the perimeter of a liner pool which holds the liner in place. There is a wide variety of liner patterns and styles to choose from which have a very realistic appearance to actual mosaic tiles. Concrete pools can either be painted with specialist pool paint or tiled with mosaic tiles.
    Coping stones for the pool surround are laid before the liner or the mosaic tiles are fitted with the final stage being the installation of your pool equipment (pump, heater and filter). This equipment is housed in a Plant Room, preferably as close to the pool as possible.

Swimming Pool Heat Pumps

Dantherm heat pumpsWhy Do All Swim Recommend A Heat Pump For Swimming Pool Heating?

There are many heating options you can choose to heat your pool water, so how do you identify which type is right for you? For a number of reasons, we believe the most sensible choice is a Heat Pump. And here’s why:

The Most Economical Choice By Far

There’s no getting away from the fact that running your swimming pool costs money; on chemicals, equipment and water heating. Whilst there are cheaper heaters you can buy, all of them will cost you significantly more in running costs than a heat pump.

What Makes Heat Pumps Cheaper To Run?

Simply put, Heat Pumps use the free and natural energy in the air, taking the latent heat out of the air, upgrading it and efficiently transferring the heat into the pool water, whilst respecting the environment. This use of free, dormant heat in the air results in substantial running cost savings – approximately 400% when using a Calorex ProPac as opposed to a standard electric heater!

The Most Environmentally Friendly Heating Option

Heat Pumps are recognised as the most environmentally friendly swimming pool heating option; the Calorex range for example produce 74% less CO₂ emissions than an oil boiler and typically have a much longer lifespan than gas pool heater options.

Which Type Of Heat Pump Do I Need?

Garden Pac heat pumpsWe stock a number of different ranges, here is a bit more information on each:

Garden Pac Inver Tech Heat Pumps

A popular budget range of heat pumps, Garden Pac Inver Tech (https://www.allswimltd.com/garden-pac-invertech-heat-pumps) have quiet DC ventilation systems and Mitsubishi DC inverter compressors – making them very quiet while in operation. They feature soft start technology and VARI SPEED, which results in slower operational speed and reduced running costs over the course of the season. The Garden Pac range can operate at air temperature down to -7°C.

Dantherm Heat Pumps

The new Certikin budget range of heat pumps (https://www.allswimltd.com/certikin-budget-dantherm-heat-pump ) are designed and manufactured in collaboration with Calorex and the Dantherm Group (a leading provider of heating solutions). There are 4 easy to install models in the range; 6kw, 8kw, 12kw and 15kw each featuring smart pool pump control, quiet operation and a reverse cycle defrost enabling operation down to 3°C air temperature.

Calorex heat pumpsCalorex Heat Pumps

Our top of the range models are the Calorex ProPac Heat Pumps, which come in 2 ranges; one designed for those wishing to swim between April and October (the Extended Season ‘X’ range; https://www.allswimltd.com/calorex-pro-pac-extended-season-heat-pumps ) and the other for those wanting to swim all year round (the ‘Y’ range; https://www.allswimltd.com/calorex-propac-all-year-round-heat-pumps).

The ProPac Extended Season X range of heat pumps can operate down to 0°C and feature a titanium heat exchanger, which is compatible for use with any type of water treatment. The All Year Round Y range are highly efficient with extremely quiet operation. Like the X range, they feature a titanium heat exchanger, providing efficient heat transfer without any dangers of corrosion and digital control panels. Capable of operating down to a temperature of -15°C, the Calorex ProPac All Year Round Heat Pumps offer a greater heat gain for a longer swimming season.

Calorex Heat Pumps also feature a comprehensive parts and labour warranty (3 Years) plus a 10 year anti-corrosive warranty on the casing.

Waterco Develop A Revolutionary New Microfibre Pool Broom

Aquafingers pool broomWaterco are an Australian manufacturer specialising in a wide range of swimming pool products. As industry leaders they are constantly looking to develop new and innovative products, and their new Aquafingers® broom is a world-first. This unique multi-purpose Microfibre broom was designed by Connie Grace, a stay-at-home mum, and is set to make pool maintenance quicker and easier for you as a pool owner.

"This is a truly innovative addition to the pool cleaning accessories category," says group marketing director Bryan Goh. "Nylon pool brooms have been in circulation for 80 years and consumers haven’t had a choice of broom that better suits the make of their pool, until now."

The Aqua Fingers® pool brush features a high-density microfibre attachment to help gently remove dirt and algae from your pool. The multi-purpose design also includes a unique, flexible body and curved underside, which ensures no awkward corners or difficult to reach areas are missed.

"This provides more angles of operation, making it quicker and easier to clean smooth surfaces,” Bryan explains. “Furthermore, Aqua Fingers® is made from flexible ethylene-vinyl acetate (EVA), which enables pool owners to clean hard-to-reach places."

That lightbulb moment

Aquafingers pool broomIn January 2017, Connie Gerace from Abbotsbury in Western Sydney returned from a four-day holiday to discover her fibreglass pool's walls and floors were covered with algae.

"I tried sweeping it off with my pool broom, but it proved unsuccessful,” she recalls. “The next day I called our local pool guy to come over and after treating it with chlorine, I asked if there was a better way to clean it. He replied, ‘If you come up with an idea, let me know.’ That’s when a lightbulb went off in my head."

Later that day, Connie attached a microfibre cloth to her broom and used it to clean off the algae from the surfaces of her swimming pool. "I could see it working and, even though I had no idea where to start, I believed in my idea."

Connie then developed a prototype with an industrial designer and pitched her revolutionary new idea to industry experts, she also approached Waterco’s Research and Development division, meeting with domestic water care product manager George Flory and senior engineer Pradeep Tandon. They both immediately saw the potential in this new invention.

"As a pool owner, I know how important it is to keep the water clean, inviting and easy to maintain," she says. "With Aqua Fingers®, all it takes is a quick sweep to dislodge dirt or algae."

Just some of the unique features that Waterco’s Aquafingers® Multi-purpose microfibre broom include:

  • Flexible ethylene-vinyl acetate (EVA) construction, making it easier to clean curved corners, ridges, crevices and steps,
  • Premium quality microfibre chenille is gentle on smooth surfaces
  • Perfect for cleaning fibreglass, tiled and vinyl lined pools
  • Also suitable for cleaning glass fences, windows, pool covers and pool coping
  • Replacement chenille attachment also available

Aquafingers® has patents pending in New Zealand, Europe, the United Kingdom, and the USA.

What Is Pre-Filtration?

Imagine filtration as a sieve;

  • large particles caught by a coarse mesh, with wide open holes
  • smaller particles pass through
  • they are caught by a smaller, finer mesh
  • fine particles pass through and so on until the finest of material is captured

Pre filtration is removing as much coarse material from the water, before reaching the primary filter. This reduces the ‘load’ on the main filter and extends filter cleansing cycles. It can also lead to better water quality.

The image below shows where Pre-Filtration is within a pool system;

Why use pre-filtration?

Prevent blockages

Skimmer and basketIf a skimmer basket wasn’t used, there is a high risk of blocking pipes and other equipment. This first method of pre-filtration is generally accepted as a ‘must’ when constructing a swimming pool, yet no further thought is given to pre-filtration.

Improve circulation

Leaf trappers (bag filters) have a large capacity and can collect a large amount of course debris before it reaches the pump. This helps the pump circulate more water without becoming blocked itself.

Improve water quality

By using a combination of pre-filtration methods, much of the coarse debris can be removed prior to the primary filter.This allows the primary filter to perform more efficiently, and therefore improve water quality. Service/cleaning cycles are extended which can also save water. Waterco’s award winning MultiCyclone is an example of how pre-filtration can be applied most effectively to improve water quality and save water.

Multi Cyclone 16 diagramExtend equipment life

If pre-filtration devices are installed, the life of equipment such as pumps and filters can be extended. Effective pre-filtration will also prevent damage to other equipment such as pool heaters and salt chlorinators.

A Waterco Multicyclone will help you save money

MultiCyclone is the brilliant new pre-filtration device that can help you save thousands of litres of water and reduce filter maintenance. Based on the principals of centrifugal water filtration – MultiCyclone collects 80% of the dirt that clogs your filter before it gets there. It drastically reduces backwashing and filter cartridge maintenance. There are no moving parts to wear and tear, and no filter media to clean or replace.

How does it work?

Centrifugal water filtration

  • Incoming water enters 16 hydro cyclones tangentially, generating a strong centrifugal effect
  • Sediment is spun out to the hydro cyclone’s wall, and then spirals down to the
    sediment chamber
  • Multi Cyclone schematicThe filtered water migrates towards the centre of the hydro cyclone and spirals upwards through the outlet

There are no moving parts to wear and tear, and no filter media to clean or replace.

  • Accumulation of sediment can be visibly monitored through the MultiCyclone’s clear sediment chamber
  • The MultiCyclone is easily cleaned by opening the valve - whilst the pump is running
  • Only 15 litres of water is discharged to cleanse the MultiCyclone



MultiCyclone Ultra combines centrifugal and cartridge filtration into one streamline housing, creating an ultra filtration system that can be vertically installed on a pool pump.

  • Dual Filtration
  • EnviroproUltra Compact
  • Ease of Maintenance
  • Save Time, Water & Energy

Features and benefits

Dual stage filtration

  • MultiCyclone Ultra uses the most advanced hydro cyclone technology to reduce the footprint of the filtration system.
  • It combines all of the revolutionary features of its predecessor with an inbuilt cartridge filter.
  • Incoming water tangentially enters its multiple hydrocyclones, generating a strong centrifugal effect.
  • Approximately 80% of the incoming dirt load is spiraled down to its clear sediment chamber.
  • The outgoing water is finally polished via its inbuilt cartridge filter, producing crystal clear water.

Extended filter capacity

  • The MultiCyclone Ultra increases the capacity of the 75ft2 filter cartridge by five times, equivalent up to a 375ft2 filter cartridge.
  • Its centrifugal section filter pre-filters up to 80% of dirt which would normally go into the filter, and drains it out.

Ease of maintenance

Extended filter capacity

  • MultiCyclone Ultra’s sediment chamber is easily cleaned by opening its purge valve.
  • Only 15 litres of water is discharged compared to a sand filter, the MultiCyclone Ultra can save between 7,000 to 10,000 litres of water a year.

Ultra compact

  • MultiCyclone Ultra’s streamline design enables installation directly to the pump out let port and Chlorinator on top of the MultiCyclone Ultra.
  • Achieving a reduction in pool equipment foot print, minimizing pipe work and reducing the filtration system’s overall head loss.

EnviroproDual cleaner

  • Benefit of placing a filter cartridge on the MultiCyclone. When the air release valve is opened, the flow of water through the filter cartridge flushes some of the large debris down through the MultiCyclone’s sediment chamber.
  • The filter cartridge is not cleansed of all its debris, but the removal of some debris during each purge of the sediment chamber, will definitely decrease its cleaning frequency.

Time Saving

  • Its centrifugal section filter pre-filters up to 80% of the dirt which would normally go into the filter, and drains it out.
  • Filter cartridge maintenance is significantly reduced. Frequency of maintenance should be equivalent to the same level of maintenance required for a 300ft2 to 375ft2 cartridge filter.

The best of both worlds

  • The MultiCyclone Ultra offers the best of both worlds. It is more hydraulically efficient than a sand filter, reducing the overall head loss of the pool’s filtration circuit.
  • MultiCyclone Ultra does not have backwashing requirements and is not dependent on a high flow rate for backwashing.
  • Smaller single speed pumps are capable of operating a MultiCyclone Ultra, reducing electrical usage and operating noise of the filtration system.

MultiCyclone Ultra offers the water savings of a cartridge filter, but without the frequency of filter cartridge maintenance.

MC12 Ultra and MC16 UltraWaterco MultiCyclone 12 & 16 Ultra

MultiCyclone 12 & 16 Ultra specifications:

  • Cartridge rating: 30 Micron.
  • The MultiCyclone 16 Ultra’s maximum flow rate is 280lpm.
  • The maximum flow rate is determined by the surface area of the filter cartridge.
  • NSF international cartridge design filtration rate is 41lpm/m2 (1gpm/ft2).
  • However, the MultiCyclone 12 Ultra’s maximum flow rate has been set to 225lpm.
  • The flow rate has been decreased to meet with a Head Loss of 5m that offers a better operating balance to lpm and Head Loss.

Waterco MultiCyclone Plus

Multicyclone UltraSaves water, energy and extends the life of pool filters Waterco Ltd has unveiled the next generation of its multi award-winning centrifugal pre-filter.

Waterco engineers have taken the MultiCyclone technology one step further and developed the MultiCyclone Plus, a vertically-mounted, all-in-one pre-filtration/filtration unit which saves between 7,000 and 10,000 litres of water a year compared to sand filtration systems.

Features and benefits of MultiCyclone Plus

The MultiCyclone Plus offers the best of both worlds. It is more hydraulically efficient than a Sand filter, reducing the overall head loss of the pool’s filtration circuit. MultiCyclone plus does not have backwashing requirements and is not dependent on a high flow rate requirement for backwashing.

A small single speed pump is all that is required to operate a MultiCyclone Plus, reducing electrical usage and reducing the operating noise of the filtration system. MultiCyclone Plus offers the water savings of a cartridge filter, but without the frequency of filter cartridge maintenance.

Dual stage filtration

  • MultiCyclone Plus uses the most advanced hydro cyclone technology to reduce the footprint of the filtration system.
  • It combines all of the revolutionary features of its predecessor with an inbuilt cartridge filter.
  • Incoming water tangentially enters its multiple hydro cyclones, generating a strong centrifugal effect.
  • Approximately 80% of the incoming dirt load is spiraled down to its clear sediment chamber.
  • The outgoing water is finally polished via its inbuilt cartridge filter, producing crystal clear water.

Extended filter capacity

  • The MultiCyclone Plus increases the capacity of the 402 ft filter cartridge by five times, equivalent to a 2002 ft filter cartridge.
  • Its centrifugal section filter pre-filters up to 80% of dirt which would normally go into the filter, and drains it out.

Ease of maintenance

  • MultiCyclone Plus’s sediment chamber is easily cleaned by opening its purge valve.
  • Only 15 litres of water is discharged

Energy saving

  • The MultiCyclone Plus’s excellent hydraulic efficiency means that a small ¾ horsepower or 0.61kW pump is capable of circulating water through it.
  • A 1 horsepower or 0.82kW pump may be required to power a suction cleaner or water features.
  • OR alternately, use a variable speed pump such as Waterco’s ECOV 100 on low speed.

Multicyclone and floor standWater saving

  • MultiCyclone Plus’s sediment chamber is easily cleaned by opening its purge valve.
  • Only 15 litres of water is discharged. Compared to a sand filter, the MultiCyclone Plus can save between 7,000 to 10,000 litres of water a year.

Time saving

  • Its centrifugal section filter pre-filters up to 80% of the dirt which would normally go into the filter, and drains it out.
  • Filter cartridge maintenance is significantly reduced. Filter maintenance should be equivalent to the same level of maintenance required for a standard 1502 to 2002 ft cartridge filter. 
How To Safety-Proof Your Swimming Pool

Finding the right safety-proofing solution for your swimming pool is a must, particularly where young children and pets are involved. You need equipment that offers reliable protection and meets your budget, so we’ve put together a little guide to help you choose the right solution for your needs:

Pool alarms

Immerstar floating pool alarm The IMMERSTAR Pool Alarm is one of the most popular alarms on the market, which complies with the French NFP90-307/A1 Safety Standards.

The sensor of the IMMERSTAR alarm detects the fall of a body and raises a powerful alarm with a 100db siren.

The IMMERSTAR fastens to the pool edge and is operated with a magnet contact key. It won’t be set off by strong winds and features LED status indicators and auto switching from swim to alert mode.

Swimming pool safety covers

Whatever your style or budget, we supply a range of manual or automatic swimming pool safety covers designed to suit all needs:

Walu manual pool safety covers

Immerstar floating pool alarmThe different types and styles of Walu Swimming Pool Safety Covers are designed to suit a variety of swimming pool shapes and sizes and are manufactured to comply with strict French NFP90-307/A1 Safety Standards. The Walu Starlight consists of strong yet lightweight aluminium bars that run across the pool width, with a fabric panel section in between each bar.

The Starlight features a sleek appearance, as the support poles are underneath the cover on this model, also making the winding and unwinding process smoother. Due to the positioning of the support bars, the Walu Starlight is only suitable for rectangular swimming pools.

The end bars are fixed to the deck via a webbing strap, which are tensioned to ensure a firm cover which completely seals the swimming pool.

Removing the cover is a case of simply releasing the tension then rolling the bars away, either with the manual Walu Crank Handle or the electrical Walu Power. Pull on one of the webbing straps when ready to unwind the cover to replace it.

Walu Air pool safety coverThe Walu Evolution works in the same way as the Starlight, but has the support poles on the top of the cover. This allows the flexibility of being able to manufacture the Evolution in all shapes, making it suitable for kidney or other shaped swimming pools.

Both the Walu Starlight and the Walu Evolution are available in either Opaque or Translucent finishes in a range of colours. The Walu Air is effectively two covers in one, as it acts as both a safety cover and a winter debris cover.

The Walu Air works by creating an inflated pillow that plugs the shape of the pool completely. This means that no debris can get in to the pool from underneath and the shape formed on top of the pool allows rain and debris to flow straight off it onto the poolside, keeping the water clear – and stopping anyone or anything getting on top of the cover too!

The Walu Air overlaps the pool by 35cm around all sides and is secured in place using traditional spring, pin and strap fixings. This cover is suitable for pools up to 11.5 x 5m (not freeform pools) with optional ladder or counter current system cut outs available.

Coverstar automatic safety cover

Coverstar automatic safety coversWidely regarded as one of the best on the market, the Coverstar is the ultimate automatic safety cover around.

At the flip of a switch, the Coverstar automatic safety cover creates an impenetrable barrier preventing children, pets or even adults from accidentally falling into the pool.

Featuring sliders 4 times stronger than traditional sliders (typically the weakest component in safety covers), choosing a Coverstar system ensures your peace of mind that your pool is safely secured.

An additional benefit is the Ultraguard III vinyl material of the fabric with heat-sealed webbing for double strength, which is also highly resistant to pool chemicals and UV light, greatly minimising colour fading. With 5 colours to choose from, you can ensure the cover complements your pool perfectly too!

Additional Coverstar System Benefits:

  • 90% reduction in evaporation
  • 70% reduction in pool heating costs
  • 50% reduction in electricity costs
  • 70% reduction in chemical use
  • Acts as a debris cover, preventing any debris from entering the pool

Coverstar systems can have either a deck mounted or in-pit installation and can be made to suit almost any shaped pool!

Swimming pool safety fencing

Coverstar automatic safety coversWhen a traditional style swimming pool safety cover isn’t compatible with a pool due to the shape or specific nature of the pool, Swimming Pool Safety Fencing offers an attractive and practical solution. Rollaway Safety Fencing is easy to install and is easily removed when not required – the perfect flexible safety solution!

Made from exceptionally strong plastic coated polymer mesh and fixed to sturdy aluminium uprights, Rollaway Safety Fencing can be affixed to concrete, grass, soil or paving. Glass Swimming Pool Safety Fencing is a stylish safety-proofing option with the added bonus of shielding the pool from the wind.
