I was having a bathtub replaced in a rental property. The plumbing is CPVC, approximately 15 years old (put in before I bought the place). Pipe do not appear to be brittle when I touch them. I've never had any leaks at this house. I'm in Florida so the pipes don't get exposed to extreme cold here. Plumber is recommending re-piping to PEX because he says CPVC gets brittle and fails over time. Is this true? I get a different answer everywhere I turn. Is it worth the expense and headache of paying someone to repipe or am I just throwing money away if I do this? Need to decide one way or the other pretty soon. Thanks!
