Common Problem
High Filter Pressure? Common Causes and Next Steps
Rising filter pressure indicates restricted flow. Ignoring it may damage the pump or filter. In Miami, high pressure often means pollen or Saharan dust has clogged the cartridge.
Most likely causes
- Dirty cartridge or DE
- Closed return valve
- Chlorine lock on filter media
- Failed pressure gauge
What to do now
Clean the filter first. If pressure doesn't drop, consider replacing the cartridge or backwashing. Persistent issues warrant a service call.
