need help with Hansgrohe valve
Hi all, I bought a hansgrohe thermostatic roman tub filler set. This is the rough-in valve # 04124181
My GC told me that it requires a special 2.5" diamond drill bit that he cannot find anywhere. I can't imagine that it would be this difficult to install since Hansgrohe is pretty popular. Did anyone else find this to be the case or perhaps there is a trick he doesn't know about?
Thanks for any advice!
