How to Use Water Hammer Arresters to Stop Banging Water Lines

If your plumbing bangs and clangs like a truckload of scrap metal, you’ve got “water hammer.” Water develops momentum as it flows fast through pipes.

How To Stop Water Hammer | HowStuffWorks

OverviewCausesIssuesExamplePreventionPurposeWater hammer is a specific plumbing noise, not a generic name for pipe clatter. It occurs when you shut off the water suddenly and the fast-moving water rushing through the pipe is brought to a quick halt, creating a sort of shock wave and a hammering noise. Plumbing that's properly installed has air chambers, or cushions, that compress when the shock wave hits, softening the blow and preventing this hammering. The chambers can fail, though, because water under pressure gradually absorbs the air.
