From time to time, you may notice unusual noises coming from your plumbing system. In some cases, they may be the result of water hammer, and you’ll likely need a professional plumber to correct the issue. Here are some helpful questions about how water hammers develop and how to handle problems in the future.

4 FAQ About Water Hammer

What is water hammer?

When you hear loud knocking in your walls or beneath your sinks, this is a symptom of water hammer. It occurs when the flow of water to your fixtures and appliances shuts off abruptly. This creates a shock wave that causes pipes to bang against the framing materials and each other.

Does it damage pipes?

Prolonged exposure to water hammer may damage your pipes, causing them to loosen at the joints or crack. Water hammer also contributes to pipe erosion and deterioration, and it’s even possible for your pipes to burst. 

How do plumbers fix it?

To fix water hammer, your plumber may install an air chamber by placing a short piece of vertical pipe near the problem valve. This allows air into a segment of the pipe, acting as a shock absorbent that keeps water flowing in the proper direction. 

How can I troubleshoot water hammer?

The next time you notice water hammer, switch off the main water valve for the affected pipes. Open the highest faucet in the home and drain the water from the lowest pipes; these are usually found in the basement or on the first floor. Leave it open to allow air to enter and create a natural cushion. Close the faucet and switch on your water supply to restore the flow to your fixtures.
