While in the middle of a 'remove old floor, install tile floor' project, i discovered a section of copper piping that is heavily corroded and pretty wet in a few spots:
I dont actually see that it is 'leaking', but it wets my fingers when i run it over a few areas... so im assuming the pipe is breaking down. The damaged section is about three feet long. It is the hot water feed to my washing machine... both the lines are laying on a concrete slab, as seen here:
Ive read a couple of articles talking about using a sweat coupling pipe (repair sleeve?), and it looks like something i could do. Would that be appropriate here? Do they make them that long?
Also wondering about how much of this i should replace. These lines are 30 years old, and there will be NO access to them once i install the tile floor. If the cold water line looks and feels good, should it be ok to not mess with it? Will replacing the corroded section of the hot water line be ok, or do i need to replace the whole thing?
Here is a pic of how the lines continue past the hole i have opened up. They basically just run up the wall about 4 feet past where i have it uncovered. They seem to look in good condition, but im no expert. I would have to remove the rest of the floor (ughhhhhhh) to access the lines.
Thanks for any help!
