You’re annoyed with your plumbing system’s banging and hammering noises and need it fixed immediately. Should you call a plumber? Or is this something you can fix?
What are the Causes?
Two leading causes for the annoying noises you have heard are Air Hammer & Water Hammer.
An Air Hammer refers to a hammer-like sound that gets released as you turn on your faucet or valve due to the compressed air that is trapped in the pockets of your water pipes.
On the other hand, a Water Hammer happens as an open valve suddenly closes, causing the momentum of the water to slam into it. An air cavity and a vacuum form further down the pipe, and water repeatedly surges until the air pressure gradually diminishes.
How do I Stop these Noises?
To stop an air hammer, you can try turning off the water at the mains, draining all the water from your pipes and then turning it back on.
This method might also work on a water hammer; if it doesn’t, you can try to slowly turn off your faucet to avoid the sudden surge of water against the valve. Though temporary, this could prevent that loud-banging noise from occurring.
Fix the Problem Before it’s too Late:
If you live in a relatively new building, air chambers are likely installed in your plumbing system to prevent any water/air hammers from occurring. Over time, these air chambers may get clogged as mineral deposits build up from constant usage. In this case, we recommend that you seek the help of a plumber to get it professionally cleaned as if left untreated, it may lead to severe and permanent damage to your plumbing.
Similarly, if you have an older plumbing system, while you can reduce the amount of water pressure to minimise the issue, hiring a professional plumber to install an air chamber would be the best solution. The longer you take to address the issue, you risk the chances of bursting your water pipes, which is a bigger and far more expensive problem.
It is better to address these issues before the problem escalates. If you notice loud banging and hammer-like sounds, we recommend that you seek the help of a professional immediately to save you both time and money.
