    Should your main drain and skimmer valve be positioned in the middle?

    Hey everyone. This is a simple and elementary question I have about where to
    position my Main drain valve and skimmer valve? I should know this, but because it's always been in position. Until now, it looks out of position to me and I think it was in the middle position, but I'm not sure. Please help. I appreciate it.

    Welcome to TFP!!!

    The valve can be in any position you want, depending on where you want to draw water from. In the picture the skimmer is partially closed so most of the suction is from the floor. That is generally opposite of what you want. Usually you only want a little flow from the floor so as to maximize the skimming efficiency.

    Welcome to TFP!

    Yep, I am normally about 80% skimmer and 20% drain for max skimming. I never go 100% skimmer in case the skimmers get clogged with leaves so there is always water available for the pump. I only switch to 80% drain when brushing the pool so it sucks up the debris.

    My valve like this is positioned just like jblizzle and pooldv recommend, about 20% from the MD, 80% skimmers. Skimming is much more important than main drain flow.

    I don't even have a MD (check my sig) so I'm on all skimmer flow. Pool circulates just fine and does well.
