Hi all,
I'm new here and looking for info on installing a Delta model 1424 LHP shower valve into a Sterling acrylic shower enclosure. The instructions that came with this valve are pretty slim. This would be a "thin-wall" installation as they call it, but they omit the details.
The attached plasterguard is secured to the valve with two screws at diagonal locations. There are also two empty diagonal screw locations where I assume the escutcheon cover installs.
Do I leave the plasterguard installed on the valve with the two screws and install it flush with the backside of the enclosure for support ? Then install the escutcheon using the other 2 screw locations ? Essentially this would "sandwich" the acrylic wall between the plasterguard and the escutcheon.
How large diameter hole should I drill in the enclosure ? I'm guessing maybe 4 inches in order to allow easy access to the screws securing both the plasterguard and escutcheon.
I've never drilled this acrylic stuff before so I don't know how easily it may crack. Is it best to use a hole saw and support the backside with a piece of plywood as I drill through ?
The second part of my question has to do with the shower head roughin plumbing. The wall above the enclosure has CBU and will be tiled. Should this be done with something like a drop elbow with the shower arm screwing into the drop elbow - which would put the joint several inches behind the finished wall? Or is it better to sweat on a bend and female fitting to have the shower arm threaded connection end up flush with the finished wall ?
Lastly, should the joints surrounding the valve escutcheon and shower arm cover get caulked ?
Lots of questions, I know. I hope they make sense.
Thanks for your time.
Charlie
