Have an issue with my far skimmer. First, it was working fine last week. I like to run my suction-side pool vac on Saturday, which I did all day yesterday. Then this morning I switch the Jandy valves back to just skimmers and the far one won't fill and work normally. I looked at it and the water is just pouring straight over the door and into the bottom of it, like a strong waterfall. This is resulting in heavy cavitation in pump and of course the pump pressure won't steady and run normal. Right now I have close skimmer fully open and main drain fully open and all is well.
And yes, the water level is at 1/2 way up from bottom of skimmer.
What is wrong here ? Thanks so much.
