The Raypak pool pump runs but has very low flow, resulting in weak return jets and poor skimming.

Safety first: Turn off power before opening the pump lid or filter.

• Clean baskets: Empty the skimmer and pump baskets completely. Check for hidden debris lodged in the basket slots.
• Inspect impeller: Remove the pump lid and reach into the impeller eye with a bent wire or your fingers (power off) to feel for debris. Remove any obstructions.
• Service the filter: Backwash or clean the filter thoroughly. Note the clean starting pressure and compare it to the current pressure to gauge clogging.
• Check for air leaks: With the pump running, look for air bubbles in the pump lid and at the return jets. Tighten suction unions, replace the pump lid O-ring if cracked, and ensure the drain plugs are sealed.
