Pool filter repair and cleaning in Lafayette, Moraga & Orinda
Lamorinda pools sit under oak, pine and redwood, so filters here load up faster than the manual assumes. High pressure, cloudy water and a heater that keeps tripping usually trace back to the filter long before they trace back to chemistry.

What you're probably seeing
Filter pressure keeps climbing
Loaded cartridges or DE grids. A proper deep clean restores flow — chemicals will not.
Water stays cloudy
Torn cartridges or a cracked manifold let fine debris straight back into the pool.
DE blowing back into the pool
A torn grid or failed standpipe o-ring. We open it up and show you the damage.
Sand filter channeling
Old, packed sand loses its ability to trap fine particles and needs replacing.
What the work covers
- Cartridge deep cleaning, degreasing and replacement
- DE grid inspection, manifold and standpipe repair, full recharges
- Sand changes and multiport valve or spider gasket repair
- Tank o-ring, band clamp and pressure gauge replacement
- Filter sizing advice when the tank is simply too small for the pool
How we handle it
1. Pressure check
We compare running pressure to clean baseline to see whether it is the filter or the flow.
2. Open and inspect
You see the actual condition of the cartridges or grids — no mystery charges.
3. Clean, repair, reset
We clean or replace, reseal the tank and log the new clean pressure so you know when to call again.

Questions we hear a lot
- How often should a pool filter be cleaned in Lamorinda?
- With the tree cover in Lafayette, Moraga and Orinda, most cartridge filters want a deep clean every three to four months, and sooner after a storm or a heavy leaf drop.
- Why is my pool cloudy even with good chemistry?
- Nine times out of ten the filter is loaded, torn or bypassing. We check the filter before recommending more chemicals.
- Can you replace cartridges the same visit?
- Usually yes — we carry common sizes, and we confirm the model with you before ordering anything unusual.
- Do you service DE and sand filters as well as cartridge?
- All three. We service and rebuild cartridge, DE and sand filters throughout Contra Costa County.
