Which pool filters need to be cleaned?
Most of all residential pools in our service area have either a DE (diatomaceous earth) filter or a cartridge filter which require to be disassembled and cleaned every 3-6 months depending on the manufacturer and application it is used in. A small portion of residential pools have a sand filter which do not require to be disassembled and cleaned every 3-6 months. A sand filter actually requires for all the old sand to be sucked out of the tank and new sand added. This is necessary once the sand particle edges have become a rounded and no longer have jagged edges to filter debris.
Filter manufacturers and swimming pool builders require regular filter cleanings to ensure their warranties are not voided. They usually recommend filter cleanings them every 3-6 months depending on which type of filter and the manufacturer. The application and surrounding of the pool can also affect when a pool filter needs to be cleaned.
Filter cleanings pay for themselves
A dirty filter that has been cleaned will often drop the average pressure on the tank by 5-15psi. This increases the flow of the water through the filter and with a clean and maintained pool filter you will:
- Get healthier and cleaner pool water– 10-20lbs of dirt, phosphates, oils and enzymes that the pool has filtered will no longer be in the pool filter so the filter can effectively clean the water as it runs through the a clean filter. Your pool water will no longer be pumped through the junk it as stored in the filter for the last 3-6 months. This also helps lower any algae outbreaks as well.
- Prolong your pool filter’s life– a cleaner filter runs at a lower pressure due to the increased flow through the filter. So there is less stress and pressure on the internals of the filter.
- Prolong the life of your filter pump motor– less resistance from the filter means it can do its job of moving your pool water more efficiently.
- Lower your electrical bill-due to the increased flow of the water through the filter. It allows the pump to draw less amps and run more efficient.
A filter cleaning is not to be confused with a filter backwash. Our filter cleanings include
- A full disassemble on all the grids and filter internals.
- Cleaning the internals and the inside of the tank.
- Using an acid solution as needed to remove any calcium buildup on the grids.
- Lubricating the backwash valve if it is a push pull or slide.
- Resealing the tank.
- Re-charging the filter with DE (if needed).
- Testing for proper filtration.
