Water hammer is the result of waterline pressure causing water pipe movement when flow is stopped or started. The “hammer” noise—which is actually a shock wave within the pipes that can lead to pipe collapse–may happen for a host of different reasons, such as insecure pipes.
If you ever notice your sink bursting out into song, consider having it further evaluated by a qualified plumbing contractor to learn more about your options—or perhaps signing it up for “America’s Got Talent.” Thanks for watching!
