When your plumbing system is running smoothly, the movement of water should be relatively quiet. Still, it’s common for commercial and residential plumbing repair companies to take calls from customers who hear loud banging noises coming from the walls and drains. Here’s some basic information on this phenomenon, known as water hammer, so you know how it’s treated by professionals.

Water Hammer & What Causes It

When you turn off a faucet or a water-based appliance like the dishwasher or washing machine, water intake abruptly shuts down. This hydraulic shock—the way the water suddenly changes directions—can make your metal pipes move. When the movement is significant, pipes can hit wood framing, resulting in a loud banging noise often referred to by plumbing repair professionals as water hammer.

Water hammer usually occurs when vertical air chambers used to provide cushion are filled with water and there’s nowhere for pressure to go. Other causes of water hammer include loose pipes that need to be properly secured or plumbing systems where the water pressure is too high.

How Your Plumbing Repair Team Can Help

Plumbing repair experts can evaluate your system as a whole to determine what’s causing water hammer. Based on their assessment, they can secure loose pipes, install additional air chambers, lower water pressure, or empty air chambers that have filled with water.

When the issue is related to a certain appliance, your plumber can install an inline water surge arrester to measure water intake and regulate flow that reduces hydraulic pressure changes. Once these adjustments are made, your plumbing system will return to its quiet, smooth performance.
