This is a Guide on Pool Filter Cleaning to help maintain your pool.
In a swimming pool, the filtration system aims to maintain crystalline and healthy water.
It rids the water of its impurities and guarantees a pleasant and safe swimming pool while contributing to the excellent maintenance of the basin.
There are different types of filters, and each one should be maintained according to specific instructions provided by the manufacturer.
How does a pool filter system work?
The pool water filtration system is an element that plays a fundamental role in keeping the pool water clean and in proper functioning order since the quality of the water depends on its effectiveness. It can be located:
• directly at the edge of the pool
• in a specifically dedicated technical room
It is mainly composed of:
• Prefilter (or a “skimmer”, a basket that retains the most significant impurities)
• Filtration pump that sucks water
• Filter that retains dirt (leaves, insects, etc.)
The filters work naturally for as long as they are correctly maintained. They must therefore be properly and regularly cleaned to maintain their effectiveness.
Before cleaning the filter
Before cleaning the filter system, you must ensure the cleanliness of the prefilter and skimmers.
As they are in the first line in the filtration chain, they retain the highest importance.
Therefore, prefilters or skimmers must be cleaned every week by being disassembled and passed carefully with water.
The filtration system must be stopped during this operation so that the significant elements usually retained cannot go further.
If the skimmer is equipped with a filter pocket, a sock, or a cartridge, these must also be cleaned once a week with water.
Cleaning the filter
Pool filters are very effective since they retain even the finest dirt particles.
There is a manometer that indicates the degree of fouling of the filter by controlling its internal pressure.
If the pressure increases by 0.3 bar or is high (in the red zone or above 1 to 1.5 bar, depending on the models), the filter must be cleaned.
There is, therefore, no recommended frequency: cleaning is based on the control mode of the manometer.
To clean a pool filter for a swimming pool, you need to:
- Stop the filtration system
- Remove the elements of the filter (the filter tank must be opened, and the cartridge must be extracted by delicately removing it)
- Wash the filter (the washing is done with a powerful water jet and a brush)
- Replace the components, making sure to reposition the tank in its location and checking that the seal is well-positioned and waterproof
- Switch into cleaning position
Pool filter cleaning is not an easy task, but it can be done with time and patience.
Pool filters are invaluable for many of the built-in features they have for removing fine particles from swimming pools.
The multi-channel valve connected to the filter also has a “counter-wash” position (sometimes called “washing” or “backwash”), which discharges the water in the opposite direction.
This allows the filter to eliminate more impurities.
