I don't see anythng about either of them in what you said. Here is what I replied to; "I've got a 1/2" tub fill valve fed from 3/4" pipe at 70 psi. It flows 6-7 GPM, and actually fills the tub pretty quick. Subjectively, it looks like a lot of water!
Unless you have a 3/4" valve and spout I doubt you'll get more than 7 GPM at the tub."
So are you now saying your tub has one of them and assuming Deb has one too?
