Why Clean Every 3 Months?
- Clarity: Desert dust and fine silt clog media and recirculate — regular cleaning traps more and keeps water sparkling.
- Sanitation: Good flow helps chlorine reach all areas. Clogged filters reduce circulation and allow algae to take hold.
- Equipment life: High back-pressure strains pumps, heaters, and seals. Clean filters keep PSI in the safe zone and extend equipment life.
- Energy: Lower resistance means your pump works less to move the same water — lower electricity bills over time.
Recommended Cleaning Schedule — Desert Conditions
- Cartridge: Clean every 2–3 months. Replace cartridges every 1–3 years depending on condition.
- Sand: Backwash as needed when PSI rises. Replace sand every 3–5 years.
- DE (Diatomaceous Earth): Bump/backwash per manufacturer. Recharge with fresh DE after backwash. Full teardown each season.
Watch your pressure gauge: When PSI rises ~8–10 PSI above your clean baseline, clean immediately — even if it's earlier than scheduled. Desert dust loads filters fast after windstorms.
5 Signs Your Filter Needs Service Now
- Return jets feel weak or "misting" instead of a strong steady stream
- PSI climbs back quickly after backwashing or rinsing
- Cloudy water that doesn't clear after brushing and normal run time
- Heater or pump safety trips — overheat or low-flow shutoff
- Sand filter: visible channeling or debris blowing back into the pool after backwash
How to Deep Clean Your Filter
- Power down & release pressure — Turn off the pump, open the air-relief valve until the pressure gauge drops to 0 PSI.
- Open the tank — Remove clamp or lid per your filter manual.
- Rinse media — Hose cartridges top-to-bottom and inside-out. For DE or sand, use the proper backwash cycle.
- Inspect O-rings & surfaces — Clean and lubricate O-rings. Check for cracks or tears in cartridges or grids — replace anything damaged.
- Reassemble & purge air — Close lid, restore power, open air-relief until a steady stream of water (no air) comes out. Air pockets cause pressure spikes and poor circulation.
Las Vegas & Henderson Tips
- After windstorms or monsoon season: Expect a quicker PSI rise. Clean sooner than scheduled — desert storms can load a filter in hours.
- Heavy landscape: Palm and oleander debris increase cleaning frequency significantly. Skim more often and empty baskets twice a week.
- Water level: High evaporation in Las Vegas — keep the waterline at mid-skimmer for proper flow to the filter.
Safety Reminders
- Always cut power and drop pressure to 0 PSI before opening any filter housing.
- Replace worn O-rings and cracked cartridges or DE grids promptly — they cause leaks and poor performance.
