I have some air bubbles flowing through my filter basket. I know that the valve to select between my main drain and the skimmer port has an air leak, I can clearly hear it when the pump is off sucking air into it. I'm not sold that this is the only air leak I have on the suction side, but I guess I'll fix the leak I know I have before I keep looking. I don't have any problems with the pump priming, holding pressure, or vacuuming.

Attached first is a picture I took of my valve (Hayward Dial a Flo) and the kit that I *think* I need to attempt to seal it back up.

Do you guys agree that those are the parts I need?

There seem to be a few 730-series out there. I found this one that is a "BA" suffix and looks like yours:


Not sure what the difference is between them or if those guts are interchangeable. Nothing else on the valve that shows a part number or anything?

Thank you. That should be all I need, right? No reason to buy the whole valve. It's all in good shape, aside from the hiss I hear when my pump is off.

I will study it harder for a part number or something if I need to.
