Your home plumbing system should function rather quietly in general. If you notice loud bangs and vibrations every time the flow of water is shut off, you might have an issue with water hammers. This phenomenon is not only annoying, it also calls for timely plumbing repair to prevent more serious damage. Here's what all homeowners should know about water hammers and why they occur. 

What Is a Water Hammer and What Causes It?

Referred to in the plumbing industry as hydraulic shock, water hammers occur when the flow of fluid stops suddenly in pipes. This can result from shutting off a faucet, but most often occurs when a plumbing appliance shuts off the flow of water. Appliances like washers and dishwashers use special valves to shut off water, which operate much faster than the human hand is capable of turning a faucet handle. 

When the flow of water is suddenly stopped within pipes, water will bang against the inside as it swiftly changes correction. This can result in the entire pipe shaking and vibrating, which also causes it to bang into nearby home fixtures, such as support beams. In addition to loud banging, water hammers can cause vibrations in faucets and handles. 

How Can You Avoid Water Hammers in the Future?

A plumbing repair specialist can install a device to address hydraulic shock in the home. Air chambers are simple solutions that involve adding extra piping to the supply pipe, which provides air cushioning to water as it changes direction. Water hammer arrestors work similarly, except these chambers are filled with gas instead of air and have a special device that keeps the gas and water separate. 

In the event high pressure in the plumbing system contributes to water hammering, a water-pressure regulator might be the best solution. These devices relieve pressure in pipes to maintain a range of 40 to 60 PSI, which is considered the normal range. Along with preventing bothersome noises, pressure regulation also prevents damage to plumbing fixtures and appliances, which can easily result when water pressure goes above 100 PSI.
