I'm trying to help my son out from long distance. His shower valves are shot, he can't get them out to change stems, they've destroyed both stems with vice grips and I'm not sure what else is wrong. When I go up there in a week or so, I am thinking of changing out shower valve body since the old one is installed with union connections. My concern is that the new body female flare part and the old tailpiece (as pfister calls it) may not mate right and leak. Attached is the old assembly and the new one I have. It looks like from the old installation that they sweated maybe a copper male fitting on the ends of the water lines and connected the tailpiece in this manner. Assuming I can get them off the lines without damaging anything I would just use the new tailpieces that are threaded and all would work. Also, is anything needed between the flange and the union or is it just torqued until there is no leakage? thanks
