Simply, a water hammer is a strange banging noise that can occur after flushing the toilet, using the dishwasher or turning on the water. It’s called a water hammer because it almost sounds like someone is taking a hammer to your plumbing. Water hammer, in reality, is actually caused by the rushing of water through your pipes.

We’ve put together a brief analysis of what water hammer is, what may cause it and a few solutions on how we can fix it.


The Causes

Even though every home is different, the source for water hammer is usually the same; a sudden rush of water causing the pipes to bang up against the walls of your home. When you turn on the faucet or flush the toilet, the water rushes quickly through the pipes and after the valve closes, it causes the water to stop rushing and cause a sudden loss of momentum. As a result, the pipes hit against the walls and create a banging noise. When you hear this noise, it’s time to call a plumber.

Other Possible Causes

A water hammer is the most common cause of loud banging noises, though they may also come from loose connections between pipes and the wall studs of your home. It can also be from excess water pressure. Simply reducing your water pressure could in fact cause the noises to cease. Either way, it is best to enlist the help from a trusted plumber, like those at All Ways Drains, for a proper diagnosis.
