Is there a problem with the sand filter in my swimming pool?
Troubleshooting a swimming pool sand filter, unlike a torn pleat in a cartridge filter or a torn grid in a DE pool filter, might be hard to find. If the pool filter media is bad or there’s a broken lateral, you can’t know simply by opening the lid on the swimming pool sand filter and looking inside.
What should I do if my pool filter is no longer round?
Clean the o-ring with water and a rag to remove any dirt and debris, and also clean the rim of the bottom tank half, where the o-ring sits. Inspect the o-ring for damage. If the o-ring is no longer round, but triangular in cross section, or if it is cracked or has dry-rot, it should be replaced.
Why is water not moving through my pool filter?
Inspect the gauge dial or face for warping, which can prevent the dial from moving. If you are certain that water is moving through the filter at a normal rate, either the gauge has failed, or there is a clog within the air bleeder assembly that the gauge screws into.
Can a large pool filter cause water pressure to rise?
Very large filters can take months, which is a nice feature for a pool owner. Some filters can have problems however, that allow pool water to bypass the filter and return to the pool unfiltered. This can cause a pool filter pressure to rise slowly, or take weeks to clean up adverse water conditions.
What should I do if my pool filter is not working?
The only regular maintenance is to clean out the filter periodically when it has captured so much debris that water isn’t flowing properly. If you have a cartridge filter, you can take out the cartridge and clean it. If you have a DE filter, you can remove the filter, wash it off, and then replace the DE.
Can a sand filter in a pool be bad?
This can happen even though your sand filter looks fine and seems to be running as it should. It can look like how it’s supposed to but not be filtering debris from your pool as it should.

What happens when a water filter is broken in a pool?
Return-side pipes or valves after the filter don’t normally clog with debris, but broken filter parts or valve parts could restrict the water flow after the filter; raising the filter pressure. Very high filter pressure can be dangerous!
