Possible Causes
Pump not fully primed, Air lock in filter or heater, Multiport valve in wrong position
How to Fix / Troubleshooting
Safety: Turn off power before changing valve positions. Open air relief slowly to avoid injury.
- Prime pump: Fill the Sta‑Rite pump strainer housing with water and ensure the lid o‑ring is sealing properly.
- Bleed air from filter: With the pump running, open the air relief valve on top of the filter until a steady stream of water comes out, then close it.
- Check valve positions: Verify that the multiport valve (if present) is set to Filter and that any bypass valves around the filter or heater are correctly positioned.
- Inspect for internal filter issues: A broken standpipe or missing internal parts can cause no pressure. If suspected, open the filter and inspect internals.
