Can you hear a loud banging coming from the pipes inside your walls?
You may be experiencing hydraulic shock, commonly known as a “water hammer”. Although this problem is common, it can lead to some disastrous outcomes if left unrectified. In this article, we’re explaining what a water hammer is, what causes it and how you can fix the issue.
Understanding Hydraulic Shock
Hydraulic shock is the technical term for water hammer, and this occurs when water stops or changes direction suddenly. It can happen when a tap or valve is suddenly closed, causing hydraulic shockwaves to move through the pipe and generate pressure. The pipes then strike against one another or against the wooding framing in your home.
A water hammer in pipes often arises on washing machines and kitchen taps. Sometimes, tenants in apartment blocks and single dwellings will turn these appliances on before they go to bed at night. If the water hammer isn’t resolved in a reasonable amount of time, it will get louder and louder. It may even dislodge water works as the pressure grows.
