My wife and I just moved into a condo that has polybutalene (sp?) pipes. the second day we owned the place, one of the pipes sprung a leak. we are told that we can look forward to many such problems as these pipes are terrible. the plumber who came out to fix the leak said that he had heard that with 3 certified occurances of pipes failing, the manufacturers will replace the polybutalene pipes with copper. does anyone know anything about this and how i can look into such? thanks!
