Why won’t my pump fill with water (prime)?
- An air leak on the suction side of the pump.
- Check to make sure the suction line is free of obstructions.
- Check to make sure the impeller is still attached to the shaft of the motor. If the impeller has broken off, it will need to be replaced.
- If the pump is installed a distance from the pool or is elevated above the normal deck level, the time needed to prime the pump could be longer. For elevated installations, a check valve may be needed on the suction line to allow for easier priming.
