Hi all, i have two skimmers on my pool (new owner of the house). This saturday I see my pump didn't priming water and my level water is halfway up the skimmer box opening. When i check my skimmers, one is priming water ok and one is not priming water in the skimmer, but when i put some water in the not working skimmer, it did prime OK. It is look like my water is too low, so the one skimmer is not prming. My question is when i look the skimmers water level inside, i see both skimmers are not at the same level. I see the bad skimmer is about 0.5 inch higher than the good skimmer. Could someone let me know is this normal? or is there something fix for this? Now i added water to 1/2 halfway up the skimmers box.
