What is Water Hammer and How Can It Be Fixed?

Have you heard water hammer of pipes during the night even when you have turned off all taps and faucets? If the hammering & banging noises in your home’s plumbing are annoying, you have a problem that needs to be fixed as soon as possible. It’s important to call a licensed plumber in Sydney like the ones at SPS Plumbers without delay, to get the problem addressed. However, here is some information that will help you understand what water hammer is.
What causes hammer in water pipes?
There are two main causes of noises in your plumbing:
• Air trapped in water pipes results in these noises. They happen when you turn on any valves or faucets.
• Water hammer also happens when you shut off the water suddenly. This often starts out with a big “bang” after which you will hear diminishing hammering sounds.
• When you turn on valves/ faucets and there is air trapped in pockets somewhere in the pipes, it becomes compressed. Turning on faucets releases this pressure and results in the loud sounds you hear.
But water hammers are a little different. The main reason why this sound occurs whenever you turn off a faucet or valve is that the water’s momentum causes it to crash straight into the valve, causing this initial hammering sound. The vacuum formed in the air cavity further down the pipe results in a repeated surge of water until the air pressure slowly diminishes.
Water hammer- diagnosis and solutions
You might be able to stop the problem, by turning off the water at your house mains, draining the water from your pipes & then turning it on again. This may work well on water hammer as well. However, if it doesn’t, the only other method to prevent it from occurring is to turn off the faucets slowly to prevent the sudden rush of water against the faucet’s valve.
All modern plumbing installations have special air chambers installed in them; these prevent the water hammer problem from surfacing. If your home’s plumbing system has these particular air chambers, mineral deposits clogs in them may be causing the problem. Our plumber would be able clean them thoroughly, and you won’t have to worry about closing the taps slowly in areas where the water hammer occurs.
If you live on an older property, you have two options. You can reduce the water pressure and check if that fixes the problem, or call us for getting an air chamber fitted into the system. In most instances, this becomes the best solution. If left unchecked, water hammer can result in pipe bursts; these can prove to be a more severe issue and more expensive to fix.
