Pool Filter Cleaning in Chandler, Gilbert

Cartridge Pool Filters

In a cartridge filter system the pool water is forced through cylindrical cartridges that trap particles as small as 10 microns.  The only way to clean a cartridge filter is by disassembling and spraying down the cartridge elements with a high pressure water.  

​

• Clean: every 3 - 6 months

• Replace cartridges: every 3 - 5 years

​

Sand Pool Filters

These filters work by the pool water passing through a 400 to 700 pound bed of  special filter sand.  Debris as small as 40 microns are trapped by the sand as the water passes through.  When enough debris is trapped the water flow is reversed by 'backwashing' and the trapped particles are removed.  

​

• Clean: when pressure rises to between 16 - 20 psi

• Replace sand: every 4 - 6 years

 

Over time the integrity of the sand is reduced and it's ability to trap particles can be greatly diminished, it is recommended that filter sand be replaced every 4 to 6 years. If you are having difficulties keeping your pool water clear it is probably time to replace the filter sand.

D/E Pool Filters

The most efficient filters  D/E filters trap particles as small as 4 microns (too small to see with the naked eye).  D/E filters contain filter elements that are coated with a white D/E powder (Diatomaceous Earth) as they start to get dirty the water flow is reversed (backwashed) and all the previously trapped dirt and debris are removed, once the water flow is changed back to normal new D/E powder is added to the pools skimmer to coat the grids once again.  

​

• Clean: every 1 year

• Replace filters: every 4 - 6 years
