I own an 1984 mobile home. Everywhere we have piping we have leaks. We are having to replace almost all piping and major flooring. I have two full bathrooms and the toliets are sinking. I have rotten boards under my kitchen sink. We have polybutylene plumbing. I bought my home in April of 2002, which is past the deadline.Is there anything I can do?? Any info would be appreciated.
