1. Cloudy Water
If water stays cloudy after chemical treatment, your filter is not doing its job. Sand filter media may need replacement.
2. Rising Filter Pressure
A pressure gauge reading 8-10 PSI above normal means the filter is clogged. Backwash immediately or replace the filter media.
3. Short Filter Cycles
Needing to backwash every day instead of weekly means the filter media is worn out and needs full replacement.
4. Visible Debris in Pool
Dirt returning to the pool after filtering means the laterals inside your sand filter are cracked.
5. Filter Age Over 5 Years
Sand filter media lasts 3-5 years. After that efficiency drops significantly. DS Water Technology supplies Hayward and Pentair filters across Delhi NCR.
