Hello, I'm remodeling a bathroom and I'm getting ready to run new water lines. I had a friend who was a plumber that told me he would run 3/4 inch lines throughout the bathroom. However, all my new fixtures have 1/2 inch rough in valves. Is there any value to the 3/4 inch lines with 1/2 inch fixtures?? It seems to me that the 3/4 inch is overkill if the water is going to be throttled by the 1/2 inchers... Help!
thanks
