Hayward Multi Port Valve Air Leak

[mwemaxxowner]

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?

I take that back. After going to this site (below), it looks like the "BA" is the entire valve, whereas the "CA" is just the inner key and seals. Seems to be the right one.

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.

I would think that's it. That's what I would change first. Good luck!

I've done that same valve repair some years back and problem was fixed.
