I have 2 problems with my pump. 1. When I change the valve to pull in water only from the skimmer the pump looses prime. It appears to not pull enough water to keep the pump going. I thought there might be a partial clog so I used a plumbing bladder attached to garden hose to try and back flush the clog out. No luck.
I then tried to blow the line with a air compressor. Here comes problem 2: I screwed the fitting into the drain hole in the pump housing. As I was tightening the fitting I heard a slight crack. Now I'm getting small water leakage from the drain plug and air sucking into the pump turning my pool into a cold spa.
Is there any other way to check for blockage in my skimmer line? I think I have cracked the pump skimmer housing. Can I replace the housing with any housing or does it have to be the exact same one?
