7 tips for maintaining your pool

DR

You have just acquired a swimming pool? What happiness! To prolong the pleasure, it is now necessary to enter it. Cleaning a pool, wintering, water treatment ... We tell you everything about how to best manage your pool ...

1. Simplify cleaning

In high season, cleaning must be done at least once a week. Broom, vacuum or robot: three options to get rid of leaves, insects and other waste, while increasing the effectiveness of treatment products. The manual cleaning is done with a net for the leaves left on the surface and a broom for the waste falling to the bottom of the basin (sand, gravel, etc.), but it is a long work and tedious. The remedy: an automatic cleaning with a vacuum cleaner, a pressure washer or a robot. Unlike household vacuum cleaners, these latest generation appliances (Bayrol, Mareva, Zodiac) operate independently. Once connected to the skimmer, the sweep of the pool or the return of water, they move alone to the bottom of the pool and suck the dirt. In the case of a robot, it is sufficient to pre-program the shape and dimensions of the pool: it then cleans the whole pool in a minimum of time, from the bottom to the walls, from the water line to the stairs. For simplified maintenance, choose a model equipped with a prefilter or a leaf trap.

2. Choosing the right treatment

To simplify the treatment of water

Most products (Arch Chemicals, Bayrol, Mareva, Waterair, Zodiac ...) perform several functions at the same time: they disinfect, fight against algae, and have a flocculating action. Others also clean the filter, which is more economical and simplifies the task. Even more practical, kits include all the necessary products for a given period of time and for a defined volume of water (disinfection, pH correction, etc.).

To rid the water of impurities, this is the role of the filter, but a preventive treatment is nevertheless necessary. Four solutions are available to you. Chlorine is the traditional disinfectant. Not only does it kill bacteria, but it also removes organic impurities that can not be filtered. It is particularly effective when the pH of the water is between 7 and 7.4. Two drawbacks however: it acts on the pH, and the chloramides it contains emit a strong odor around the basin. Bromine is a natural and effective disinfectant against bacteria, viruses and fungi, even at high pH. Big advantage over chlorine, it is odorless. Active oxygen is one of the best disinfectants for the human body. At the same time, it ensures disinfection, clarification of water and the fight against algae. Only disadvantage, it is suitable only for low volumes, 50 to 60 m3. PHMB. Odorless and tasteless, this polymer is effective whatever the pH. Advantage: it is only consumed when the pool is busy. Disadvantage: it does not destroy algae.

To know. In addition to treatment with chlorine or bromine, the installation of an ozonator makes it possible to halve the consumption of disinfectant products, reduce the hardness of the water and prolong the life of the installation. Indeed, housed in the technical room, this unit transforms oxygen into ozone and disinfects water in a natural way (Clair Azur).

3. Treat the water effectively

In season, the pool requires a weekly treatment, even every two days if it is very hot: pH check (which must be between 7.2 and 7.6) and possible correction, flocculant diffusion to clarify the water, disinfection ... When you can not be present every day, it is better to opt for multifunctional disinfectants slow diffusion (proposed by all major brands). For 15 days, or even 2 months for the best performers, pebbles diffuse their bactericidal, algicidal and clarifying power. The floating diffusers (Marina) act in the same way by releasing little by little (during 1 to 3 months) the doses adapted to the complete treatment of the water. On your return, a diagnosis will however be necessary, possibly followed by a shock treatment, because the water balance of a swimming pool remains unstable.

4. Keep the water at a temperature

To extend the season or simply increase comfort, the installation of a heater is necessary. An electric heater. This is the simplest solution: the water circulates inside the unit, placed on the discharge pipe and heats up in contact with the heating elements ... A heat exchanger. It allows to heat the pool from the existing boiler (gas or oil) via a bypass of the hot water circuit. An exchanger ensures a rapid rise in temperature (1 to 2 days for water at 28 ° C) ... A heat pump. She draws calories from the air and transfers them to the pool heating system. The investment is heavier, but quickly amortized because, for 1 kWh consumed by the compressor, the CAP returns 4 or 5 kWh. A solar collector. With an area between 30 and 70% of that of the pool (depending on the region, the volume of the pool, the desired temperature), the panel (Blue Square, Clipsol) is installed in the garden or on a roof.

5. Outsource the interview

Two possibilities: or take out a maintenance contract with your pool, or install an automatic control station. The maintenance contract. Most swimming pools offer à la carte contracts: simple intervention for start-up and wintering, weekly maintenance throughout the season, periodic delivery of treatment products, etc. From 400 to 600 € for two visits in the year (wintering and commissioning) up to a few thousand euros per year for weekly maintenance with pH verification, disinfection and cleaning. The Bayrol Pool Manager ("Reva3Cool" from Mareva). Probes continuously measure the pH of the water, its rate of disinfectant and algaecide, and an electronic regulator controls the injection of products into the pond (pH corrector and / or disinfectant). Some models offer the possibility of programming different dosing times week and week-end. However, even if such an installation strongly reduces the interventions, it does not dispense with it. Count around 1 400 or 1 500 euros for the resort (excluding products).

6. Install a summer blanket

This is especially useful when you are often away. A summer cover makes it possible to save treatment products by limiting the pollution of water (leaves and other debris), to avoid evaporation and finally to lengthen the bathing season by limiting thermal losses. . There are different models of summer tarpaulins (polyethylene, extruded polyethylene foam, with or without bubbles, anti-UV treated, etc.), all very simple to install, especially if we double them with a retractor. To know. Unlike bar rugs or floating shutters, floating rugs do not provide pool safety (watch out for falls). However, there are now PVC shutters with transparent solar blades that absorb the heat of the radiation and warm the water (Deceuninck).

7. Think about wintering

This is mandatory when the temperature of the water is below 15 ° C to protect the devices, prevent scale deposits and proliferation of algae, and ensure easy restart. Wintering takes place in several stages: cleaning of the pool, skimmers and the filter; pH adjustment between 7.0 and 7.4; shock treatment followed by the application of a wintering product; lowering the water level to 10 cm below the discharge nozzles; closing water inlets; installation of an opaque tarpaulin which limits the photosynthesis responsible for the multiplication of algae. In the spring, when the water exceeds 15 ° C, the pool can resume service after thoroughly cleaning the walls, bottom and filter. Once the water level is up, the pump and filtration are restarted and the water is analyzed and adjusted if necessary. To know. Start water treatment at least one month before the start of the season to allow disinfectant products to benefit from a cumulative effect.
