I bought a house with an indoor pool that has a Jacuzzi Magnum 1.5 hp pump. The pump leaks. I have changed all of the seals and o rings and it still leaks. The leak appears to be coming from the large o ring that is on the motor and goes inside the housing with the large lock ring to secure it. I have the o ring lubed and put lube on the inside of the housing.
Correct me if I’m wrong, but that o ring is the only way to keep the entire pump from leaking at that location.
Any thoughts
