I think I understand what the valve does and how to set it in general, but I'm not sure what the different uses are.
Currently I have a 3-way Jandy Valve which when set toward the direction of the pool has the suction line on with the skimmers off and the opposite side would be suction off and the skimmers on.
I have two main drains, but I don't think they are connecting because no matter which way the Jandy Valve is set there doesn't seem to be any suction at the main drain. I understand that there are two drains in order to lessen the suction...but I don't feel anything at all coming from them regardless of valve position.
So either the main drains are both completely clogged or the main drain line isn't connected to the system at all.
Anyway my question is what are the different reasons for wanting the skimmer off or the suction off. Also is an in between position doing anything? I'm wondering where the Jandy Valve should be set for general circulation and cleaning respectively.
I was going to use this picture for a demonstration of what my setup is like, but I think it answered some of my questions. The one I hadn't asked yet..being if I set the valve in between does it shutoff one side some and open up the other side more.
If I understand right putting the Jandy Valve in the middle will have both skimmers and the suction line with the same flow rate while putting the valve in between either section gives more flow to one of the sides.
If I put the Jandy Valve at a 45 degree angle toward the skimmer side that means the suction line will have 75% flow and the skimmer 25% while if I put it at an angle toward the suction line it'll be the opposite....(or it might be the exact opposite of what I said lol)
Do I have that right? Hope all that made sense....
