Scottpat Posted February 4, 2009 Report Share Posted February 4, 2009 I found this yesterday during a 1 year warranty inspection. Home was about 10 months old. The metal hangers were reacting with the copper and had started to corrode and leak. I stopped counting the number of spots in the crawl after 15.

energy star Posted February 4, 2009 Report Share Posted February 4, 2009 I would have the builder replace them all. Quote Link to comment Share on other sites More sharing options...
Darren Posted February 4, 2009 Report Share Posted February 4, 2009 They almost look like sections of chain link fencing. Quote Link to comment Share on other sites More sharing options...
hausdok Posted February 4, 2009 Report Share Posted February 4, 2009 I see those occasionally. They're often copper-plated steel and the copper plating just sort of dissolves and rust is all that's left. OT - OF!!! M. Quote Link to comment Share on other sites More sharing options...
Richard Moore Posted February 4, 2009 Report Share Posted February 4, 2009 Had these throughout the crawl in a 1980s home. All in similar condition. Nothing actively leaking, but I recommended a plumber remove them, clean and check all pipes, and replace them with appropriate hangers. Oh, and also add insulation.

No. Quote Link to comment Share on other sites More sharing options...

No. Well, this one did not leak until by back hit the pipe and it moved the hanger. Failed under testing [:-magnify Quote Link to comment Share on other sites More sharing options...
