Hey guys, sorry if this has already been asked, but I didn't see a lot of results for Polybutylene using the search function.
So today I had a plumber come out to make repairs on the main drain line (darn tree roots). While he was here he offered to take a look at the water heater as well, because his company was running a special on water heater maintenance/replacement. When he got the water heater he immediately stopped and said "ouch, you've got Poly". Then he went into a pitch about repiping the house now before it fails. His company would charge $4-5 thousand for the repiping, so he's hardly an unbiased resource.
Looking online it seems that these Polybutylene pipes are a pretty big problem, so I don't think my plumber was being dishonest. However, isn't this kind of what home insurance is for? I mean, sure, if I wasn't a mustcian with the resources to deal with random expenses like a water leak-- I would understand replacing working pipes. But I have a large emergency fund for this sort of thing.
Am I insane, or does "if it ain't broke..." apply here?
