What's That Banging Noise Coming From My Pipes?

The house is filled with noises of children running around and playing, the television in the living room with family members, and laundry spinning within the drying machine. The one place that isn't expected to hear to hear a loud noise is the plumbing. What happens if you notice an abrupt banging sound coming through your pipes? It could be known as the water hammer. In this article, we'll go over the meaning behind it and what it is that causes it, and the best way to fix it.

What is a water hammer?

A water hammer, technically called hydraulic shock, is when pressurized water slams against the pipe's walls or shuts off a valve (when you shut off the faucet for instance). It's a typical plumbing issue; however, it's not something that should be overlooked. In addition to being annoying, the water hammer could put additional strain on your plumbing system, which could eventually lead to the possibility of a leak.

What are the causes of water hammer?

There are many reasons that could lead to loud pipes in your home. It's crucial to identify the root of your problem so that you can make the appropriate steps to tackle the issue.

Air chambers with water

Air chambers are the vertical pipes that are incorporated into the plumbing systems. They are created to control pressure and allow water to flow easily. If there's too much water inside the air chambers, they're not able to perform their task.

The good news is that you are able to reset your air chambers simply by shutting off the main shut-off valve for water and turning on all water faucets in your home (including the outdoor hose and bibbs) and draining the water from the plumbing.

Pressure fluctuations in appliances

In the event that the water hammer is only occurring when you're running the washing machine, dishwasher, or sprinkler system, the fluctuation in water pressure caused by the appliance may be the reason. The addition of a water-hammer stopper to the appliance will be able to solve the issue.

High-pressure water

It is more likely that you will experience water hammers when your home's water pressure is excessively high. A simple way to test this is to purchase the water pressure gauge kit at a home improvement shop.

Before you run the test, ensure that you shut off the faucets, and shut off all appliances that require water. Attach the gauge to the hose of the bibb (outdoor faucet) and then slowly open the valve until it is fully opened. The gauge will provide you with an indication. If the gauge says that your pressure exceeds 80 psi, then the pressure in your water is too high and you'll need to install an air pressure regulator.

Pipes that are insecure

If pipes aren't properly secured to the structure of the home, the fluctuation in the pressure of water can cause them to shake. It is common to identify the pipes that are loose and creating the noise then fix them using support pipes as well as a plumber's tap.

There are other reasons for water hammers, however, these are the most prevalent. If you are experiencing loud pipes, call us today!
