Plumbing back to back shower valves
I am plumbing 2 showers that share a wall (back to back). In order to get the hot and cold supplies to the proper side of each valve requires lots of twists and turns. I was advised by someone to just use ½” male threaded connectors on the supply lines (sweat fit to copper) and then simply use those braided faucet hoses to go from that connector to the valves. It sounds reasonable and much simpler than trying to sweat 20 elbows in a small area. Is this a safe (meaning leak-free) way to plumb this project or am I inviting trouble down the road? Thanks for any advice.
