A choice may be self-evident!
If you're planning an overflow or indoor pool, opt for a liner.
In all other configurations, you are free to opt for a liner. More flexible than on-site lining, your liner will be manufactured directly in our French workshops, to the exact dimensions of your pool, and installed by your piscinist.
How to choose your colour?
Colours that make a difference!
Color is what you notice at first glance, and choosing a liner is all about giving your pool a style. Contemporary or classic, dark or light, the colors DEL colors allow you to perfectly match your pool with its surroundings and the style of your home.
Liner colors change once the pool is filled with water: visit our gallery to discover the effect of each color once the pool is in water!
How to maintain and protect your liner?
Cleaning
During the season, it is recommended to clean your liner once a week.
After emptying the skimmer and pump pre-filter baskets, clean the water line with a non-abrasive, solvent-free product, then sweep the walls and bottom of the pool. Finally, backwash the filter to prevent clogging. Cleaning the water line is important to get rid of limescale deposits, greasy substances (such as sunscreen) and even micro-algae.
You can complete your cleaning with a robot cleaner, whose capacities will be adapted to your pool and its dimensions.
It is also advisable to renew a third of your pool's water every year to avoid isocyanuric acid saturation, and to replace the filter media at least every 5 years (or as recommended by each filtration system).
Wintering
You can winterise your pool when the water temperature is below 10°C.
Opt for a winter cover to prevent dead leaves from settling to the bottom of the pool. Otherwise, clean the pool frequently to prevent impurities and plants from staining the liner.
Maintain your normal water treatment or use a special winterization treatment.
To prevent frost damage to your pool or its filtration system, we recommend using an anti-freeze device (gizzmo) or lowering the water level. Don' t touch ice formations, as they could cut the liner.
Water treatment and balance
Maintaining the pool and its water is very important to improve the liner's lifespan. Poor water balance can lead to staining and wrinkling of liners. The capacity of the pump and its filter should enable water to be filtered for 4 to 6 consecutive hours. To find out the filtration time, apply the following formula:
Filtration time = water temperature / 2
It is imperative to run your pump daily, especially in hot weather.
The water temperature should ideally not exceed 28°C, however, some of our liners are suitable for temperatures up to 33°C.
It is important to respect the pH of the water:
- PH between 7 and 7.4
- TH between 8 and 25 °F
- TAC between 8 and 12 °F
Water maintenance must be carried out using products specially designed for swimming pools. Several solutions are available:
- Inorganic chlorine, whose the level must be maintained between 0.7 and 1.2 mg/l. It is advisable to couple it with a stabiliser to guarantee its effectiveness.
- The stabiliser or isocyanuric acid which must not exceed 70 mg/l.
- Bromine should not exceed 2 mg/l.
- PHMB has been banned as a disinfectant since 2008 and must no longer be used.
DEL recommends the Chemoform brand products, to be found at your swimming pool specialist!
