O.K. Problem solved ! Thanks very much Rubicon. We bought another Phoenix bathroom faucet and looking at it in the box we just couldn't believe the shower diverter would be any different that what we had. So we tried a simple inline shutoff valve . . . nope. Tried the Oxygenics shower head . . . nope. Finally bit the bullet and installed the Phoenix replacement and voila . . . no leaks anywhere. That's not to say the original from Escape was faulty . . . we were probably pretty hard on it trying to pull & push that tiny diverter knob way too hard. AND . . . the replacement procedure turned out to be pretty easy. My husband HATES anything to do with plumbing because there's usually a leak somewhere when all is said and done. Not so today . . . we're celebrating
So nice to wash my hands in the bathroom without the shower head dripping on me
