Maintenance & Safety Tips
-
🔧 Power Down & Relieve Pressure: Always shut off your pump and bleed system pressure before changing cartridges.
-
📈 Monitor Gauge: Replace when pressure climbs 8–10 psi above clean-start levels.
-
🗓️ Seasonal Swap: In most climates, swapping once per season keeps flow high and energy use low.
-
🚿 Rinse, Don’t Soak: A thorough garden-hose rinse between seasons extends life—skip harsh chemicals.
