Understanding the Effects of Water Hammer on Pumps and Pipes

June 4, 2019

Have you ever turned off your pump or faucet only to be greeted by sudden loud banging noises? When you hear your plumbing system recoil from your regular operation, you are likely being introduced to a concept known as water hammering. Water hammer is a real issue that impacts plumbing systems throughout the world. Today, we are going to explain what water hammer is, why it happens, and what you can do about the issue should it become a problem in your home.

True Impact of Water Hammer on Pipes and Pumps

While 'water hammer' doesn't sound like a real thing, it absolutely can impact your day-to-day living. Also known as hydraulic shock, water hammer problems can become quite serious. You'll notice hydraulic shock issues when you turn off your water or reverse the flow of your water. This banging noise is coming from a shock wave that is moving throughout your system. While the sound itself is incredibly annoying, the actual impact that it can have on your plumbing is even worse. Water hammer can be such a problem that your pipes can break, your plumbing joints can loosen, and your pump can end up out-of-order. Your next question is probably simple, how can you prevent water hammer from happening?

1) Install Mechanical Shock Arrestors - Also known as water hammer arrestors, these handy devices can help to put your water hammer issues in the past. Your water shock arrestor will work to absorb the shock from your water hammer problem. Inside of your arrestor, you'll find a spring as well as an air bladder that'll work in concert in order to absorb water movement.

2) Install a Regulator - If you have a water pressure problem in your plumbing, you need to install a regulator. When your water pressure is out of wack, water hammer can begin to occur. You'll notice water hammer from pressure-related problems in your laundry room, your kitchen, and even your outdoor water features. Traditionally, your home should have a water pressure level of between 30 and 55 PSI. Sometimes, that pressure level can get up to over 100. In those instances, water hammer is the likely outcome. A regulator will help you to pull the water pressure in your home down to a safe level.

3) Secure Your Pipes - Finally, you can also address your water hammer issues by securing any and all loose plumbing pipes in your home. You will likely want to call on a certified plumber to handle this portion of your work.

Water hammer can be more than just an annoying sound. Water hammer can directly damage your pipes, your pumps, and even your plumbing joints. Don't let water hammer ruin your day, address the problem today and call the experts here at Parker Pumps.
