Advice from your local pool service company
Every filter needs the correct maintenance method and a working circulation system
Cartridge filters use removable elements, sand filters use a bed of filter media and backwashing, and DE filters use grids or elements coated with diatomaceous earth. Each type has different cleaning, handling, and replacement needs.
A pressure gauge provides useful information when compared with the clean starting pressure. High pressure can indicate restriction; unusually low pressure may indicate weak flow, air, valve issues, or another circulation problem.
Filter maintenance should follow manufacturer instructions and local disposal requirements. Damaged elements, cracked tanks, leaking valves, or persistent flow problems require repair rather than repeated cleaning.

Frequently asked questions
Which pool filter is best?
There is no universal best choice. Pool size, water goals, maintenance preference, plumbing, equipment pad, water use, and budget all matter.
Should I clean a filter every time pressure rises?
A meaningful rise above clean pressure is a common signal, but follow the manufacturer’s guidance and confirm the gauge is working.
