As part of a bathroom remodel, I'm taking the opportunity to replace rusty old galvanized throughout the whole house with copper.
I have 1" copper from the street to the meter in the house (about 30').
From the meter it's about another 70' to the furthest fixture.
The hot water heater is right smack in the middle of that.
I was thinking of running 1" from the meter to the back of the house with 3/4" branch lines for the fixtures. First, does that sound approximately correct? I've looked at the fixture unit tables (I have 30 Fixture units total) and it seems like that's basically correct.
One of the tables I read though considered the feed to the hot water heater a branch line though which would make it 3/4"? That doesn't seem intuitively correct to me though? Shouldn't the main hot supply line be the same size as the cold--so 1" into the hot water heater, and 1" out?
Thanks,
Joe
