Is there any benefit to using copper for drains instead of abs, pvc or cast iron?
The above all seem to have their own benefits and draw backs over eachother, except copper that I know of.
Is there any application where you need to use copper drains rather than the others? I have a large home that is all abs underground and 1st floor, then cast in the ceilings and 2nd floor for sound.....then there's a sewage ejector that uses a 2" copper drain. I don't get it, why use copper for that?
The ho wants me to replace the copper drain (crawlspace) because it developed a pinhole leak. What draw ago do I have replacing it with abs?
