I'm installing a Delta R1000 rough in valve body into new construction. I'm not a plumber, but because of lack of resources here in Mexico where I'm building, I have to install it myself.

I have a question about the location of the front of the plastiguard bonnet. The instructions say it should be flush with the wall. Do they mean flush with the unfinished wall, or should it be mounted so that the front of the plastiguard will be flush with the anticipated level of the finished and tiled wall?
