Plumbing concerns can be hard to diagnose, and if they are left for too long, then they can result in serious issues. If your pipes make a banging sound when appliances such as your washing machine, dishwasher, or water faucet shut off, you may have a condition known as "water hammer."  A common issue in many homes, water hammer can easily be eliminated by your plumber. Consider the frequently asked questions below to learn more.

A Guide to Water Hammer

What is water hammer? 

Hydraulic shock, more commonly known as "water hammer," occurs when the water flowing through your pipes suddenly stops or changes direction, typically when the flow is disrupted by a blockage or an abrupt valve closure. This sudden stop creates a shockwave, causing your pipes to strike against one another or the surrounding framing, leading to the familiar hammering sound.

Does it affect all pipes?

Water hammer is more common in older pipes that lack the air cushions needed to help regulate pressure. While less common, it can occur in newer pipes when these air chambers become blocked or waterlogged. While many believe water hammer is more prevalent in metal pipes, it is just as common in plastic, although the sound it makes is less noticeable.

Can it damage my pipes?

While the most common symptom of a water hammer is a loud and unpleasant sound, it is indicative of a more significant and damaging problem that should be addressed by a plumber. These issues are often blockages or failing pipes. If left untreated, the force of water hammer can rupture pipes, cause valve failures, bend internal system mechanisms, and overstress pressure gauges. 

How can I fix it?

A mild case of water hammer can be prevented by tightening loose pipe straps, or by installing foam pipe insulation to act as a shock absorber and prevent them from banging together. It can also be treated by installing an air chamber, or a short segment of vertical pipe, near the affected valves. This method provides a cushion for water to rebound into after sudden shut-offs or directional changes.
