Chlorine bowl cleaning tablets and your toilet

Have you ever wondered what happens to copper drain lines when you use chlorine bowl cleaning products? The picture above should scare you. The picture shows a three inch copper DWV pipe removed from a closet bend. Needless to say it was a pretty bad leak. I've seen this on commercial bar sinks also. Replacing copper DWV with plastic pipes is the best solution on them, unless it's a fire rated building in which case cast iron may be needed. On them, it's the combination of limes and lemons I believe. Terry
