What Is Water Hammer? Causes, Risks, and How to Fix It

Normally, water moves through pipes with consistent momentum, and when a valve or tap is shut off slowly, the water gradually comes to a stop. However, when the shut-off happens suddenly, the momentum of the water has nowhere to go. This surge of pressure bounces back and causes vibrations, which you hear as a loud thud or bang.

Why Water Hammer Is a Problem

Many homeowners dismiss the noise as a minor irritation, however ignoring water hammer can lead to costly plumbing issues. The repeated stress from hydraulic shock can damage your pipes, fittings, and valves. Over time, the constant vibration may loosen joints and lead to leaks. In extreme cases, it could even burst a pipe.

Additionally, a water hammer can shorten the lifespan of your appliances. Washing machines, dishwashers, and water heaters can all be negatively impacted by the pressure shock. If you’re noticing recurring noise after shutting off water fixtures, it’s time to contact a plumber before the problem worsens.

Common Causes of Water Hammer

Water hammer often results from fast-acting valves found in modern appliances. When these valves close suddenly, they generate the pressure surge that causes the banging noise. However, other causes include loose pipes that aren’t properly secured, high water pressure in the home, and the absence or failure of air chambers or water hammer arrestors.

In older homes, air chambers were often installed to cushion water pressure changes. These chambers can become filled with water over time and stop functioning properly. In newer plumbing systems, arrestors serve the same purpose, but if one fails or was never installed, water hammer can occur.

How a Plumber Can Help

Fixing a water hammer typically requires the expertise of a professional plumber. A licensed professional can inspect your plumbing system to identify the source of the issue and recommend the most effective solution. This might involve draining air chambers to restore their function or securing loose pipes in Fullerton, CA with straps and fasteners.

If high water pressure is contributing to the problem, your plumber may install a pressure-reducing valve (PRV) to bring the water pressure back to safe levels. This not only prevents water hammering but also reduces wear and tear on your entire plumbing system.

Professional plumbing repair services can also assess whether the piping in your home is appropriately sized and routed. In some cases, improper pipe design can make your system more susceptible to water hammer. A plumber may suggest rerouting or upgrading certain sections to eliminate the issue permanently.
