Safety & Maintenance Tips
-
Power Down First: Always shut off the pump and relieve system pressure before removing or installing the cartridge.
-
Watch Your Pressure: Replace when your filter gauge climbs 8–10 psi above the clean-start reading.
-
Seasonal Swap: In most setups, swapping cartridges 1–2× per season keeps your flow high and energy use low.
-
Rinse & Reuse: Give it a thorough garden-hose rinse between seasons to squeeze every last drop of service life out of it.
