Water Hammer is Called Hydraulic Shock

Properly called hydraulic shock, water hammer is a common home plumbing problem with a simple solution. Not only does water hammer cause a loud knocking or banging noise after shutting off a faucet to quickly, but it is also known to cause the faucet and fixtures to visibly vibrate. What’s really happening to cause all of these effects? Well, water is being forced through the pipes, exerting pressures at hundreds of pounds per inch.

Why it Happens

The common cause of water hammer is mechanical. Appliances (commonly washing machines and dishwashers) or faucets shut the water flow off too fast. This defect in the plumbing mechanism is the main reason why homes experience hydraulic shock. But this is not the only possible cause; water hammer can also be from having old or outdated plumbing. Fixtures and appliances can all have older technologies that are not best for preventing sudden water flow stoppage. Namely, dishwashing and washing machines are designed with solenoid valves that are notorious for stopping water flow to suddenly.

The most common solution for hydraulic shock repair is the addition of air chambers, which are a type of pipe fittings that act as a shock absorber. For a long term solution, water hammer arrestors are usually incorporated into a plumbing system, which are a more complex version of air chambers.

What to Do About It

If you have a water hammer issue, be sure to act fast. You might believe it is just an annoying aftereffect of your plumbing pipes, but really, it can cause extensive damage if neglected overtime. If you had a water hammer repair done several years ago, they could be outdated by now. Although it is possible for homeowners to repair their own water hammer problem, it is best left to a licensed plumber who retains the proper permits, training, and professional resources to get the job done up to code.

Is your plumbing system noisy? After you shut off a faucet, do you experience a loud bang, a strong vibration, and a lingering hiss?

Continue reading to learn which options you have for repairing water hammer in your plumbing system.

What is Water Hammer?

Technically referred to as hydraulic shock, water hammer is one of the most common noisy plumbing issues; but noise is not the worst part about it. Water hammer is actually damaging to your plumbing system, and should be addressed in a timely manner to prevent costly plumbing repairs, appliance repairs, and pipe replacement. The sounds and reverberations experienced at the time water hammer occurs is a result of water traveling through your plumbing pipes at thousands of feet per second while exerting hundreds of pounds of pressure per inch. But what causes water hammer to begin with?

When water is traveling at high speeds and extreme pressure through your plumbing pipes, an abrupt halting of the water flow (shutting off the faucet or valve quickly) will cause the resulting noise and reverberations. The loud bang you hear is actually the pipes colliding with one another and against other framing components of the home. This is where the damage can happen. Homes are usually fitted with a plumbing piece called an air chamber to absorb the shock produced when water is traveling at high speeds under high pressure. Air chambers are generally fitted on the hot and cold water lines near the faucet or water intake valve. They are usually not visible, and sometimes hidden inside walls. Older homes may not have air chambers but should, and newer homes are usually equipped with them already.


If your air chamber is filled with water, you can solve this problem by draining your plumbing pipes, thus restoring the air back into the chambers and recharging your plumbing system. For a long-term solution, you could have your trusted master plumber install an engineered or mechanical water hammer arrestor. These devices are charged with air or gas, and do not fail under pressure. The best solution for preventing water hammer problems is to have your plumbing installed properly, the first time. If you are concerned about the condition of your home’s plumbing, talk to your local Indianapolis plumber for inspection, diagnostic, and repair services.
