Get Rid of Water Hammer Sound Effectively


Plumbing in San Diego Visualize yourself racing at breakneck speeds only to realize the road up ahead is closed. You slam on the brakes as hard as you can, but you know there’s no way to stop. Then, bang! Imagine water moving along your pipe at the same breakneck speeds, only to come to an abrupt halt because of a closed valve. The result: water hammer!

What is Water Hammer?

Water hammer is the sound of water slamming against the wall of the pipes as it comes to an abrupt stop. While this may seem normal to you, it’s a symptom of a bigger issue. Whether or not the valves are closed, water should still be able to flow naturally to produce an even and steady sound. This is aided by the air chamber found at the junction of the pipe and the faucet. The air chamber absorbs the shock coming from the abrupt cessation of water movement.

What You Need to Understand about Water Hammer

Because water hammer is the sound produced by water as it comes to an abrupt stop in narrow pipes, you need to understand that distance, time, and velocity can all significantly affect it.

The longer the distance water travels, the greater its forward momentum, hence the greater the force needed to stop it. The faster the valve closes, the more abrupt is the stopping of the water’s forward momentum. The faster the water goes, the greater the tendency to create water hammer.

Unless you’re backed by a San Diego plumbing company, Perry Plumbing says you should know how to best address water hammer.

How to Fix Water Hammer

The air chamber is one of the most important components of your plumbing system. Make sure it’s fully functioning so that it can absorb the impact of slamming water. You need to shut off the main water valve and open the faucet located on the highest part of your house.

Open the faucet in the lowest part of your house to help facilitate the complete draining of water from the pipes. After that, close the lowest faucet and then reopen the main water valve. This should push all of the remaining air in your pipes, but retain the air inside the air chambers.

While many homeowners don’t necessarily look at water hammer as inherently bad, over time, this can lead to pipe and valve damage. When severe enough, it can weaken the entire pipe joint. Ensure air cushion in the air chamber to help eliminate water hammer.
