I wanted to have a tankless installed under my bar, but the plumber that was going to do the work says that it will be very expensive to do since it requires extra copper pipe to install a T&P valve. Apparently the code for the city he works in requires it. The manufacturer does NOT require one....because its not needed. I had no idea the code applied to separate cities.
Is this right or are they just being lazy?
