How to Stop Water Hammer (Before It’s Too Late!)

Water hammer is a hydraulic shock that typically occurs in old pipes after a valve is shut off suddenly. A series of loud bangs also occurs when there is an increase in water pressure in your water line.

So, if you live in an old house, you may think that it’s strange why there are banging noises inside your walls after you stop showering or using a washer. But it is not. It is normal for old pipes to get worn out at some point. And in this case, they absorb shock less from changes in the water pressure as you (or other appliances) rapidly open and shut off water supply flowing through the pipes.

For example, washers automatically control water flow from fully on to off within seconds. So, this sudden stoppage causes a hydraulic shock that makes your pipes bang against other fixtures. Over time this can lead to disastrous burst pipes and water leaks!
