Pool Filter Cleaning and Replacement in Frisco and Collin County
Filter cleaning $95; cartridge and grid replacement from $180
Look at the pressure gauge on the filter. If you know the number it showed when the filter was last cleaned and it is now 8 or 10 psi higher, the filter is due. If you do not know the clean number, the signs are the same. Weak return jets, a heater that drops out on low flow, a cleaner that barely moves, and water that will not come fully clear. In Collin County a filter works year round, so there is no winter break where it catches up.
Cartridge filters
Most newer pools in Frisco run cartridge filters. Cleaning means shutting the pump off, bleeding the tank, removing the lid and the cartridge, and hosing every pleat from top to bottom. That handles dirt. It does not handle the film of body oil, sunscreen and calcium that builds through a swim season. A deep clean soaks the cartridge overnight in a filter degreaser, then an acid rinse where scale is present. The tank o-ring is lubricated and the gauge is checked before the lid goes back on.
A cartridge that stays dirty, pressures up again in days, or shows frayed fabric and cracked bands is replaced. Replacement runs from $180 depending on the size and the brand.
DE filters
Diatomaceous earth filters polish water finer than anything else and are the most work to maintain. Backwashing flushes some DE and dirt but leaves the grids coated. A teardown every few months pulls the grid assembly, hoses and soaks each grid, and checks for tears that let DE back into the pool. Manifold o-rings are replaced and the filter is recharged with the right amount of fresh DE. The old DE and backwash water go to the sanitary cleanout, not the storm drain.
Sand filters
Sand filters need a backwash when pressure climbs and a sand change every five to seven years. Channeled or calcified sand passes dirt straight through, and no amount of backwashing fixes it. A sand change means removing the old sand by hand or vacuum, inspecting the laterals for cracks, and loading new media. Glass media is an option that filters finer and lasts longer.
Why it matters more here
Clean filters move more water with less pump energy. With a pool pump running most of the year, that is a real electric bill difference. A clogged filter also starves the heater and the salt cell, which both shut down on low flow. Most of the heater no-fire calls we take in Frisco start with a filter that needed cleaning a month ago. After a green pool cleanup, the filter needs attention again within a week or two because dead algae loads it fast.
What the visit includes
A pressure reading before and after. A full clean of the cartridge or grids, or a backwash and media check on sand. Inspection of the tank, clamp and o-rings, and a pressure check for leaks on restart. The clean baseline is written on the tank so you and the tech both know the next due point.
Pricing
A filter cleaning is $95 for a standard residential filter. Deep soaks on heavily oiled cartridges are a small add-on. Cartridges, DE grids and sand changes are quoted by filter model. Weekly service customers get filter cleanings scheduled automatically when the pressure calls for it.
Note the number on the pressure gauge before you call (972) 640-4665. That reading tells us whether a cleaning or a new cartridge is the better fix for your pool in Frisco and across Collin County.
