Flexible Impeller Pump Will Not Prime
Q: Pump was working, but now will not prime. Fitted new impellor + gasket. checked for air leaks, still no joy. could the rear lip seal be worn?
A: If your pump will not prime with a new impeller fitted the issue is either an air leak in the suction hose or wear within the pump body that is allowing air past the sides of the impeller.
