Just went through a battle with my pump. Couldn't get it to prime after it ran dry while I was traveling for a few days... Replaced all the seals and rubber parts and inspected the rest, now it is working.
I am having issues with my pool cleaner 4x. It is moving VERY slowly around the pool, but otherwise seems to be functioning.
I am seeing about 15 PSI on the filter. That isn't much different than I normally see.
I have played with the jandy valve that adjusts between the main drain/skimmer and the vacuum cleaner.
What I have observed, which never happens normally, is that when I adjust the jandy to put more suction on the pool vac, I see a dramatic drop in filter pressure...<5 psi. With the reduced pressure, the pool vac runs even slower (basically stops) despite allocating more pressure towards it.
Additionally, I seem to have a pretty consistent flow of air bubbles coming out of the return jets. That has been a pretty consistent thing since I bought the house 3 yrs ago... But worth noting that the seal replacements didn't fix that... I have no above ground air leaks that I have been able to find.
I am thinking it has to be some kind of leak or obstruction in the pool vac line...?
