Water hammer can cause serious damage to pipes and plumbing fixtures, and can be loud enough to be a nuisance.

These valves can stop the water moving through the pipes very suddenly, which sets up a shock wave through the water. This wave can cause the pipes to vibrate and ‘shudder’, which can lead to damage and noise.
