The quick answer
A pool filter should be cleaned according to pressure rise, flow, debris load and manufacturer guidance—not by a calendar alone. Restoring normal flow helps circulation and clarity.
What filter cleaning involves
The correct process depends on whether the system uses cartridges, diatomaceous earth or sand. Service may include depressurizing the system, opening the filter, cleaning elements or grids, inspecting visible parts and restarting the system safely.
Use the clean-pressure baseline
Record operating pressure after a proper cleaning. A meaningful rise above that system-specific baseline can signal debris restriction. A pressure change may also come from baskets, valves, water level or a pump problem.
North Texas debris loads
Pollen, grass, dust, leaves and storm material can load a filter quickly. Construction activity and windy weather may shorten the interval even while the pool still looks clear.
Cleaning versus replacement
Cleaning cannot repair torn grids, cracked manifolds, brittle cartridges or damaged seals. Worn parts should be identified before they allow debris to bypass the filter.
How weekly care helps
Weekly visits can monitor pressure, flow and clarity. A full filter teardown is periodic maintenance, not a task needed every week, and should follow the equipment manufacturer’s procedure.
