    bypass skimmer

    to test the theory of the skimmer being cracked, is there a way i can bypass the skimmer and use the main drain. i have jandy valves

    Depends on how your pool is plumbed. The easiest way to take the skimmer out of the equation is to put an expanding test plug or gizmo in the skimmer outlet opening. You'll still have water in the skimmer though.

    Re: bypass skimmer

    Bypassing the skimmer by changing valves will only isolate the skimmer plumbing. If there is a crack where the skimmer is installed, or in the skimmer body itself, then plugging the pipe for the skimmer or changing the valve will not stop the crack from leaking.

    Based on your other thread here: pool-leaking-t72201.html, I did not think you suspected the skimmer pipes. Can you provide more detail on what you are trying to bypass?

    i tried tip fill the pool halfway up the skimmer opening. it turns on, and then all the water seems to get sucked in, its gone, refills and during this a ton of gargling noises is happening.

    Re: bypass skimmer

    uploaded a picture of the equipment and valve settings, maybe that has something to do with this?

    Re: bypass skimmer

    The valve on the right-hand side of the picture is controlling where the water is coming from as it exits the pool and is pumped to the filter. Right now, it is drawing from 2 sources in the pool at about the same rate. It looks like one side might be throttled back just a little. You can try moving the valve all the way to block one pipe and see if you can tell what that stops. Then turn it the other way and see if you can tell what that stops. If one of the pipes is from the main drain, it will be difficult to know what happened. If one is from the skimmer, that should be easily apparent.

    All that said, the behavior you describe sounds like either the skimmer weir is stuck, or you don't have enough water in the pool. Make sure the skimmer weir (flap near the opening of the skimmer) is freely moving. If it is operating properly and water is free to flow over it, add more water to get about 2/3 up the skimmer opening.

    How long did you let the gurgling happen before turning off the pump? Did you watch it go through the cycle of filling/draining a few times?

    Re: bypass skimmer

    it was almost instant with the noise, i watched the water be sucked down and noise started. like a toilet flushing is the best way to describe it.

    on the right meaning, the right side in the picture? should i move it ?

    Re: bypass skimmer

    meant to ask, any specific way to move the handle.

    Re: bypass skimmer

    The right side meaning the one shown on the right side of the picture, yes. The one nearest to the pump. That's the one that controls the water from the pool and into the pump.

    You have a 3-port jandy valve. Here's a picture showing how it works: http://www.poolplaza.com/pool-school/pl ... tion.shtml (left-hand side of the diagram, the right-hand side is a 2-port which is not what you have). You want to turn it so that one of the pipes coming from the ground is blocked. Turn on the pump and see what happens. Then with the pump off again, switch it so that the other pipe from the ground is blocked. Turn on the pump and see what happens.

    (You probably can't physically turn it to block the pipe going into the pump; if you can, make sure you never leave it set that way.)

    Also note: it's not shown in the diagram, but the way the valve is set in your picture, it doesn't block any of the pipes, so all of the ports are open. Water is flowing from both pipes from the ground and into the pump with this setting. It looks like one pipe may be partially blocked which will slow it a little, but it won't stop it. Hopefully, this makes sense.
