2 Questions - Copper Pipe and Bathtub
1) If redoing a bathroom (gutting), is it necessary to replace all the copper plumbing? My drains and supply lines are all copper. The house was built in 1963. Does copper last forever, or should everything be replaced. The drains seem to be in fine shape when I look inside them, so is the toilet copper drain.
2) Is there a standard center point for a bathtub drain hole. I heard it is 15" from the wall (stud). If a joist is in the way, can it be notched out an inch or so to accomdate the drain connection on the bottom? When measuring 15" from the stud, I come next to the joist. My joists run parallel (the long way) with the tub. And can the drain run off to the side of the tub instead of straight down the middle?
