Q: Tim, every time I shut off a faucet in my home, my water pipes rattle and make a dreadful sound. It seems to me that they might burst. The problem is common in many houses on my street, as I’ve asked my neighbors if they have the same problem. What’s happening? Did the builder or plumber make a mistake when installing the pipes? Is there a danger of pipes bursting and flooding? Is there an easy fix, even DIY? Help before I need a life jacket! — Pam H., Clearfield, Pa.
