What It Means
Persistent High Filter Pressure
Likely Causes
- Sand channeling in filter (water finds path of least resistance through channels rather than filtering)
- Filter needs new sand (sand wears and rounds after 5-7 years)
- Broken lateral in sand filter base allowing debris bypass
Next Checks
- Spike backwash cycle — some filters allow a pressure spike to break up sand channels
- If sand is 5+ years old, replace the sand
- Inspect laterals at bottom of sand filter for cracks — broken laterals allow sand into pool and reduce filtration
