Hello everyone my first post here, came over from John Bridge Tile Forum. Will start with a THANK YOU for this site. I'm in the process of re-doing the shower I have bought the valves they are Grohe 3/4" inlet/outlet. A thermostatic for the temp and two dirverter valves also 3/4" , one for the Hansgrohe "RAIN" hand held shower head and one for the 2 Grohe body sprays also 3/4" inlet. House has galvanized plumbing that will be replaced after bathrooms are done. The hot water heater is just on the other side of the side shower wall, runs under the house with 3/4" then into 1/2" in run the length of the house with 1/2" branches to the sinks and shower (1 shower 2 Kohler toilets) the cold is 3/4" the length of the house with 1/2" branches to the needed areas. After the bathrooms are done the house will be repiped with copper
* My question is will I have better pressure with the 3/4" valves or should I have bought 1/2" valves I can return them but 15% restock fee. THANKS
