Just replaced 1965 era DW supply from meter from 1/2 to 3/4 copper and added in a PRV. Now working on main HW line. Two questions I have.
First, I am adding a 40 gal HW heater tank being fed from existing boiler HW line. Boiler has expansion tank on cold water feed already. Do I need to add another expansion tank on boiler output HW line feeding into new HW heater tank?
Second, coming off HW heater I was thinking about using 3/4 until after 2nd floor bath feed (sort of as a 'manifold' effect) in order to minimize HW warm up time to fixtures. If both 1st and 2nd floor are using HW, the 3/4 could supply both adequately without effects of just a 1/2 HW supply throughout and potential HW 'starvation' to both.
Thanks.
