What is the best way to avoid overheating Hansgrohe Thermostatic shower/tub rough-in valves while sweating the ½†supply lines? These valves only have female threads. My dilemma is how to affix threaded male-to-sweat male fittings to the incoming water supply lines while keeping the valve plumb in the wall cavity. (The piping leading to the showerhead and tub will not pose a problem.) This is new construction in that the wood-framed walls encasing the valves are accessible from both sides. There are 5 valves at stake. I’m remodeling all three bathrooms in our home and really need some good advice.
Reading threads in the Shower and Bath forum (especially thread #1846), I came up with three ideas, but I'm unsure if any are the “best way†to proceed.
The first idea is to first assemble a copper threaded male-to-sweat male, a 90 elbow, and about 15-inches of vertical piping for each supply line. Affix both assemblies to the valve with Teflon tape and adjust the entire assembly, via the amount of tape used, so the fittings are properly tightened yet still lie in the same plane. Last, sweat couplings to affix this assembly to the supply piping lower in the wall cavity.
The second idea is to disassemble each valve, remove the heat-sensitive parts, cover the valve with a damp rag, affix the threaded male fittings, and solder away.
The third idea is to use copper threaded male-to-CPVC slip fittings for the supply lines, continuing with CPVC piping to get out of harm’s way, and then transitioning back to copper at a safe distance.
Please critique these ideas and inform an anxious amateur what would work best. This is my first post. Thank you!
