Generic O-Rings for Pentair Backwash Valve?

[Mark Shvitz]

Does anyone here know the specs for generic O-rings to fit a Pentair 14930 slide backwash valve? I don't want to spend $20 for $3 worth of O-rings, and I don't want to spend a week waiting for Ebay. If I have the specs, I can go to the hardware store.

Searched for a long time, gave up and posted a question, and then found the answer in a few minutes. Sorry about that. In case anyone else wants the information, I will provide it. O-rings come in different hardness grades, and I believe the correct one here is 70 Durometer.

#331 (2-1/4" ID x 3/16") -- 2

#232 (2-3/4" ID x 1/8") -- 1

#014 (1/2" ID x 1/16") -- 1

These things are dirt-cheap on Ebay, and for all I know, my local hardware store has them.

The backwash valve is a model 14930 Swimquip. Seems vastly inferior to ball valves, but I am stuck with it.
