My husband is freaking out because he discovered our house has polybutylene pipes for all the water pipes in the house. Technically, we knew this when we bought the house, because it was in the inspection, but neither of us knew what it meant. He was talking to our contractor who pointed it out, and the contractor said somehting like, "You have poly pipes. That suuuuucks." So now my husband thinks we need to have them replaced before we have a massive leak on our hands. Does anyone have this type of pipe in your house? Did you replace it, and if you didn't, did you have a leak? In case you don't know what the pipes are, here's a link http://www.polybutylene.com/poly.html
