Does your sink ever sing to you? I recently came across such a sink at a home in Oak Harbor. The song? A little ditty called “water hammer.”
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!

Water hammer is a specific plumbing noise, not a generic name for pipe clatter. It occurs when you shut off fast-moving water suddenly, bringing it to a quick halt and creating a sort of shock wave and a hammering noise. Fix “water hammer” by draining the plumbing system. Open the uppermost faucet (or the one furthest from the water meter) and the lowest (or closest to the meter) and allow the water to flow to a lower-level sink or floor drain. Draining the system restores air to air chambers. Close the lowest faucet and refill the system. For more detailed information see this article.
