My water heater was relocated a few years ago to save space and the plumber didn't really divert any of the pipes. Instead, he just extended a few which resulted in a really long run from my heater to my kitchen sink. It takes a good while to get hot water. I've thought about diverting the hot water line over to the kitchen with a copper T but I'm starting to worry that it might diminish my water pressure. It's 3/4" copper coming out of the heater and it switches to 1/2" copper just before it diverts off the main line and goes to the fixtures as you can see in the drawing. Any recommendations?
