Jay Posted April 27, 2009 Share Posted April 27, 2009 Ok heres my problem. I have this needlewheel pump for my skimmer. It was working great for the last 9 months or so then it kind of quit making good bubbles. I took it apart and cleaned the mesh modded impeller and that did not help. I then took it apart and trimmed the mesh thinking that it was rubbing on the housing of the pump. This did not help either. Then I checked the inlet of the pump by putting my finger on it and its barely sucking any water when before it would really slam my finger when I put it near the inlet ( if you know what I meen I hope (scratch) ) So I took it back out and discovered that the airline was comming out of where it was glued in place so I removed the airpline and cleaned up the surface and reglued the air tubeing in place where it was before. This still did not help it so just to test I plugged the airpline and wham....the pump starts pumping water like 2000 gph like it is supposed to so I really dont think the pump is bad and the impeller seems to spin and pump just water like its supposed to. When I unplug the air tube and allow air back in the pump starts cavitating and rattleing some and the water flow is dramatically reduced. It does make bubbles but when I hook it up to the skimmer body its obvous it is not right. sooooo what makes it cavitate and rattle. Can someone fix it? Should I just buy a new pump which I have no problem doing. If I buy a new pump should I do the mesh mod to it? Frustrating...really.
