A clean filter is the single best thing you can do for water clarity and equipment longevity. Pools Plus provides thorough filter cleaning for sand, cartridge, and DE filters — full disassembly, inspection, and pressure testing throughout Placer County and Sacramento County.

Every filter type has unique cleaning needs. We handle them all with the right chemicals, tools, and techniques.
Cleaning Process:
Backwash to flush debris, then deep chemical cleaning of the sand bed to break down oils and grease. Inspect laterals and multiport valve.
Recommended Frequency:
Backwash monthly. Deep clean annually.
Signs It Needs Cleaning:
Cloudy water despite good chemistry, high filter pressure, sand in pool, channeling in sand bed.
Cleaning Process:
Remove cartridges, soak in degreasing solution, high-pressure rinse pleats, inspect for tears or flattening, reinstall with clean housing.
Recommended Frequency:
Clean every 3-6 months. Replace cartridges every 2-3 years.
Signs It Needs Cleaning:
High pressure gauge reading, reduced water flow, cartridges look gray or oily, tears in pleats.
Cleaning Process:
Disassemble grids, acid wash if coated with calcium, inspect fabric for tears, reassemble, recharge with fresh DE powder.
Recommended Frequency:
Clean every 3-6 months. Recharge DE after every backwash.
Signs It Needs Cleaning:
DE powder returning to pool, high pressure, grids caked with scale, torn or damaged fabric.
A proper filter clean goes far beyond a quick rinse. Here is what every Pools Plus filter service includes.
Check pressure gauge reading, inspect for leaks, and assess overall filter condition before disassembly.
Safely drain, open, and disassemble the filter. Remove cartridges, grids, or access the sand bed.
Soak in specialized degreasing solution, high-pressure rinse, acid wash if needed, and inspect every component.
Replace O-rings, re-lubricate seals, reassemble to spec, pressure test, and verify proper flow and pressure.
A clean filter traps debris efficiently. A dirty filter lets particles circulate back into the pool, causing cloudiness and dull water.
When a filter is clogged, the pump works harder and runs longer to push water through. Clean filters reduce pump strain and electricity use.
Excessive pressure from a dirty filter stresses the pump motor, heater, and chlorinator. Regular cleaning protects your entire system.
Clean water circulates chemicals evenly. A dirty filter creates dead zones where algae and bacteria can grow despite proper dosing.
