    What is the max water level relative to skimmers?

    We had a few heavy rain storms recently. The water level is higher than the top of the skimmer opening in the pool. As a result, water is not being skimmed. I assume we want to keep the water below the top end of that opening, right?

    Lazy-L shaped pool and a spa. 22.5k gallons. Pentair VS pump. Pentair cartridge filter CCP520. STA-Rite SR400NA heater (400K BTU). Leuder limestone coping. Pebble sheen (blue granite) Wooden deck.

    You are correct. You'll get filtering but no skimming action the way it is.

    If my water gets just before the top of the skimmer opening and especially above it, it finds some way to get between the liner and wall so I try to keep it at mid skimmer.

    recomended level is from 1/3 to 1/2 up the opening from bottom of skimmer as long as it doesn't suck air

    The floating door or weir in the skimmer rises and falls with the level of your pool. It essentially changes the height of your skimmer opening according to water level. it is also like a one way valve for debris. If the water level is too high the debris will be blocked by the top of the skimmer opening. I keep my level about an inch below the top of the opening. This is a little high, but the high water level helps my autocover to glide more easily.

    So much rain this spring has my pool level kissing the top of my skimmer opening weekly. Free backflushing but I'd like to get more CYA in my pool, not less. (A good problem to have I suppose) Good to hear what levels are best for skimming.
