Copper Drain Pipe Corrosion
Posted by Bill Edwards on September 03, 1998 at 22:27:51:
I have 3" copper drain pipe and it is corroding in several areas. Why would this occur? The pipes have been in the house for about 40 years. The corrosion is mainly located near the dryer which is not vented outdoors so there is plenty of humidity in the area. Would this be a factor? Across the basement away from the dryer the pipe is in good shape with no corrosion visible. What is the cause for this corrosion?
