I just installed a Delta Universal rough-in valve body and valve for tub-only application. Delta calls for 8" minimum drop to elbow, only have room for about 4-5". Delta customer service said this minimum distance is necessary to prevent "shower-rise".... so, no shower, no problem, right?
Well, I hear a high-pitched ringing or whistling noise coming from the valve body. I have a cap on the top outlet of the valve body (for shower connection). If I remove the cap, the ringing sound stops.
From the "shower-rise" idea, I would figure water would be coming out the top, but actually it seems to be drawing air from the top. I feel slight suction when I use my thumb to cover it, and a second later, a loud ringing.
I had CPVC run down for the tub spout originally. Replaced with 1/2" iron pipe... made no difference.
If I remove the tub diverter, no whistling sound... but, obviously I need this.
If I remove the valve body cap on the top, no whistling sound... but, I'm bit leery about sealing up access to the valve without a cap. (And I've already tried obstructing the water coming out of the spout to see that water comes out here.)
Please help!!
Is this minimum distance to the tub spout necessary to prevent this ringing/whistling sound?
Thanks, Jason
