Hi! Happy to find this forum. I am new here and I've searched this forum and have found all sorts of good advice but unfortunately have so far had no success. Here's the problem: My pump turns on fine. It seemingly builds up pressure pretty good but is only sucking a little bit of water through. (I say the pressure seems fine because when I remove the basket lid, you can hear the pressure relieve - and it instantly sucks up the water sitting in the basket.) I'll run the pump for a while and only a little water comes through (I am going to waste here, so it must not be a filter problem-right?) When I turn off the pump, water swooshes back into the basket from the pressure side. (Could it be a blockage on down the line? that doesn't seem right since it would have to go through the strainer etc) Here is what I have done: I repiped all suction side piping, taped, lubed etc. I can't believe that theres any air coming in there. I dont have a snake but I did have a TV cable I could twist and turn to get through the underground pipe (from the skimmer to the pump) and it went through no problem. I even put some drain opener down there. *At one point while running the pump I heard a thump which sounded a lot like a clog moving from one position to another, but after opening all pipes leading to the pump, I found no clog. Bizarre. So then I thought maybe its the impeller on the pump. Well, I had that aprt and it is clean. I took member name WASTE's advice and reached in to the back of the pump with my 7/16 and turned it back and forth (was able to do so) but that didn't have any effect. Other details: the pressure gauge isn't moving - just sits at 5psi. I was vacuuming fine before the problem started. Then at one point after that the pump was 'surging' (psi would go up and down from 5 to 12 psi). Sorry for all the detail but I figured if I was going to get any help you should have as much detail as possible. Any ideas?
