Frequently Asked Questions

SEASONAL MAINTENANCE

1 - When my pool is in a state of active winterizing, should I switch off my salt chlorinator?

It is not recommended to operate the salt chlorinator in water that is too cold (below 15°C). When the temperature decreases, development of algae and micro-organisms slows down: consequently, occasional chlorine dosing is sufficient during winterizing.


2 - My pool water is turning green: what should I do?

First check your stabiliser level. If it is too high, the disinfectant cannot be effective. Another possibility is that your filtration time is too short to be effective in treating your water. If this is the case, make it longer. If the problem persists, a complete analysis of your pool water by a professional pool specialist is recommended, to determine if it is correctly balanced and whether it contains excessive levels of nitrates or phosphates.


3 - It’s spring! Can I use my pool cleaner to clean my pool for the first time this season?

Absolutely not. Your robotic cleaner is designed for regular maintenance of your pool. Spring cleaning using a cleaner would risk clogging it up excessively. So it is best to clean manually the first time.


4 - What should I do to make sure my passive winterizing goes well?

Firstly, lower the level of water in the pool by a third, consider installing winter floats in the pool and in the skimmers.
Remember to empty the various pieces of pool equipment: pump, filter, heat pump, salt chlorinator. Add winterizing product to stabilise the water, and lastly, cover the pool.
If you have any doubts, don’t hesitate to call a professional.


PUMPS

1 - In the last few days, I have seen bubbles in my pump prefilter: why and what should I do?

There are 2 possibilities: either there is an incoming air leak in the suction circuit upstream of the pump, or it is a phenomenon known as “cavitation”, generally due to an obstructed pipe.
You therefore need to check the pipes and the seals in the network upstream of the pump.


2 - I need to change my pump, is it a good idea to get a more powerful one?

No. This would risk reducing filtration quality, because the water would pass too quickly through the filter: a pump is always sized to work with a filter.

On the other hand, you can take the opportunity to swap for a variable speed pump which circulates water permanently at low speeds. Result: it is super silent and electricity consumption is reduced by up to 85%*

*Potential savings of 65% are generally observed


3 - My pump no longer starts up and makes an electric groaning noise, what should I do?

This is a classic malfunction of the start-up capacitor. To make sure of this, start up the pump manually by pushing the fan round with an Allen key. If it starts up, replace the capacitor.

I have noticed a leak underneath my pump. What should I do?

If you detect a leak in tthe lower part, it is highly likely that the rotary union is the problem (mechanical seal).
To change this union, you will need to obtain either just this seal, or the union kit which includes all static seals and the mechanical seal all together.
This intervention is not very complicated but if you are not a fan of DIY, ask your pool specialist to do it.
However, do it quite quickly to avoid irreversible damage to the motor.
In most cases, a leak from the seal is a result of operation of the pump when it is not submerged (water is not passing through it). It is of primary importance that the pump always operates when submerged and with water passing through it, especially during priming phases.


FILTERS

1 - I see water seeping out of the used water outlet of my valve when it is in the filtration position. What should I do?

Your spider gasket is very likely to be damaged. It must be replaced. To ensure it lasts for a long time, only manoeuvre the valve when the pump is not operating.


2 - How do I take the sand out of my filter?

Close the valves, then take off the cover. If you have a vacuum cleaner suitable for the purpose, vacuum up the water and sand together from the filter. Otherwise, drain the filter, then take the sand out by hand.


3 - I have re-opened my pool but my pressure gauge indicates a high pressure of 3 bars. What should I do?

Pressure gauges are quite fragile and they are damaged by freezing conditions. For this reason, yours may need to be replaced because a pressure of 3 bars appears improbable.


WHITE GOODS

1 - How do I guarantee watertightness between the main drain and the union?

It is entirely possible to glue this part in place and thus ensure it cannot be dismantled. Since the main drain is embedded in the concrete, it is highly unlikely that it will need to be dismantled. This is often carried out by professionals to avoid any risk of leaks.


2 - I have a choice between 2 skimmer models: I am tempted to buy the cheaper one. What do you think of this idea?

Keep in mind that to replace these parts, you will need to break areas of the wall, which will cost much more than the potential savings made when purchasing the skimmers themselves. Always choose robust and high-quality white goods that will last longer.


SANITIZATION

1 - I have been advised to check the total alkalinity in my pool. What is this and what do I need to do?

The total alkalinity, which can be checked using test strips, is an illustration of the mineral content of your water. If it is too low or too high, it prevents pH equilibrium of the water from being correctly maintained. Due to winter rains, the mineral content of your water is low. To raise the total alkalinity to the right level, simply add alkalinity increaser to your pool.


2 - What advice can you give to simplify sanitization of my pool?

Select a more automated system! For example, you can choose a simple chlorinator, a salt chlorinator or a liquid chlorine injection system.


3 - I have heard that bleach could be used to sanitize the water in my pool. What do you think of this idea?

The use of bleach in a pool is not advisable, because on the contrary to liquid chlorine, bleach is not a concentrated product and it is therefore difficult to dose correctly. Also, when it is used the water is likely to cause scaling and its high pH requires the use of a corrector (acid).


4 - I have found rock salt that is much cheaper, can I use this without damaging my salt chlorinator?

Absolutely not! Salt chlorination systems require a special and extremely pure salt. Any other product would result in their permanent destruction.


LIGHTING

1 - Is it possible to change the colour of the spotlights in my pool?

You can of course exchange your classic bulbs for LED lights to have colour lighting. They can easily be changed. In addition, you will save money on electricity because LEDs consume less energy than classic incandescent bulbs.


2 - Is it really necessary to install pool lighting if I don’t plan to swim at night?

It is a good idea to have a lighting system for security reasons: if an animal or a person falls into the pool in the dark, you will be able to intervene more quickly thanks to your lighting.


CLEANERS

1 - My electric cleaner no longer climbs the walls. Why not?

This is probably due to saturation of the filter grids. Therefore, suction is not created and the cleaner cannot adhere to the walls. Check them, clean them, or replace them if they are too clogged up.


2 - Can I swim whilst my cleaner is cleaning the pool?

No. No matter how the cleaner is operating, you must not swim under any circumstances
while it is activated: you would be taking real and serious risks.


HEAT PUMPS

1 - In the instruction manual for my heat pump, I have read that there is a “heating priority” function. What is this?

In order for the heat pump to function, filtration must be activated. Heating priority prevents the heat pump from stopping until the desired temperature has been reached.


2 - For my heat pump, I have been advised to install a circuit breaker that is more powerful than the circuit breaker recommended by the manufacturer. Can I do this?

Absolutely not! An over-dimensioned circuit breaker does not provide protection for the equipment. Always comply with the type and amperage that is recommended in the instruction manual.


3 - Since the price of electricity is lower at night, would it not be preferable to operate the heat pump during night hours?

Absolutely not! Since night air contains far fewer calories than air during the day, the heat pump would then be much less efficient.
On the other hand, we recommend covering your pool when you are not using it to maintain the temperature.


CONSTRUCTION / RENOVATION

1 - I would like to have a pool built: where do I start?

Firstly, you must have a specific idea of what you want. Firstly set out a budget, and ask yourself the right questions: location, use, type of pool, equipment, schedule. Always seek advice from several professionals before choosing the right partner for your project.

Make sure you plan your project in advance: as summer approaches, pool specialists’ order books fill up and the clients who signed first will be served first!


2 - How do I know where to install my pool?

5 criteria must be taken into account for a well-chosen and successful installation: orientation, safety, intimacy, maintenance, technical feasibility.


3 - How many years should I leave it before renovating my pool?

After 10 to 15 years, it is highly likely that you will need to replace the liner: use the opportunity to re-do the waterproofing around white goods. This will also be a good opportunity to acquire next generation equipment like a heat pump, a salt chlorinator...
