Is it ok to use 3/4" fixture rough in with 1/2" supply lines for a shower?
Posted by Mark on March 21, 2002 at 14:57:33:
I am remodeling my home and have existing 1/2" water supply lines. The new Hansgrohe fixtures (Thermostatic regulater, volume control and diverter)that I just bought have 3/4" inlets and outlets. Is it ok to reduce down to 1/2" at each conection without causing any reduced pressure or volume? Also would I be better off just running 3/4" piping for the rest of the shower rough in after the first conection or does it matter?

Any help would be appreciated.
