    Circular Logic

    Please explain this plumbing to me.

    The left valve controls suction. The more left the valve, the more the skimmer works.

    The right valve controls return. Turned left the whips operate, turned right the wall returns operate.

    When the left valve is turned right and the right valve is turned left, nothing works and the psi drops from 20 to 12.

    I checked to make sure the valve handles were properly attached, pointing in the right direction, they are.

    You have something figured wrong here. The only place suction and return meet is at the pump, not in a Tee in the plumbing.

    Re: Circular Logic

    What's written on top of the piping? I can't make it out in the picture.

    What does the horizontal valve control?

    It's my writing, ignore it.

    I don't know what the horizontal valve does, it was hard to move and I didn't want to break something. I will try it later

    Re: Circular Logic

    My thinking is that one side is the spa and one side is the pool.

    Can you post a pic of the pump pad?

    Re: Circular Logic

    There's only one body of water.

    The pump pad plumbing is not confusing. Suction and return. The plumbing in the picture is where it gets confusing.

    Re: Circular Logic

    I'm totally not getting that setup. I must be wrong, but it looks like your suction side water & your return side water can somehow intermingle.

    Re: Circular Logic

    The way I see it, that middle pipe can either be a suction or a return depending on how you set the valves. If you turn them both toward the center you're just recircing water from the discharge to the suction of the pump.

    Re: Circular Logic

    I believe that the middle pipe is setup so it can be either a suction or a return line.

    If I am correct, one of the two left hand pipes is skimmer and the other is pump intake. On the right, one of the two would be filter and the other returns. Than leaves the middle pipe to be "whips" whatever they are.

    They are return side cleaners. They attach to the sides of the walls.

    Pools are not built with them anymore because they don't work nearly as well as floor heads / nozzles.

    Re: Circular Logic

    I have never seen the pics of the whips before. My pool built in the 70s has the returns for them, but I use the 4 eyeball return path instead.

    Re: Circular Logic

    I discovered the reason for why the pool plumbing is the way it is.

    The whips are supposed to be retractable. The suction is supposed to suck the whips back into the plumbing.

    It does not work for me. It could be because so many of the whips are missing.

    The whips do not look like the ones in the pictures I posted earlier, they are simply smooth rubber hoses.

    Re: Circular Logic

    That sounds like a neat idea if it actually worked. I've never heard of that setup before. Thanks for the lesson.
