I'm new to the forums and after searching, I am still unable to troubleshoot my problem.
I can't seem to get my pool vacuum working to what it was a few weeks ago. When I have the water feature on, I get a 15psi and the vacuum doesn't move at all (tiny vibrations in the hose). When the water feature is turned off, I get a 20psi and the vacuum begins sucking, but very little. I don't see any air bubbles in the return side.
I found a leak to my water feature and have fixed that issue. I have looked at and replaced all the o rings (vacuum leaf basket, leaf basket and pump). I also looked at the impeller and it didn't look like there were any obstructions.
Any other thoughts for helping me troubleshoot this issue? The pump is older (5+ years) and the sand in the filter hasn't been replaced in a few years either (5 years).
Thanks and sincerely!
