Installation & Compatibility Notes

Shut off the pump and relieve pressure before opening the filter housing.

Reassemble the tank, restore system flow and verify proper operation. Monitor the pressure gauge to establish a clean baseline reading.

Maintenance Tips

When filter pressure rises 8–10 psi above the clean baseline, inspect or clean the cartridge.
Rinse the element with a hose during routine maintenance; replace when fabric frays, collapses or no longer cleans effectively.
Keep replacement cartridges on hand to reduce downtime during service calls or seasonal maintenance.
