Why do my pipes make a rattling noise?
This banging or rattling noise is often referred to as “water hammer”, and it’s caused by a blocked vent pipe in your plumbing. Water moving through your pipes can create a vacuum, which is normally dispelled by a vent that pokes out through the roof near your faucet or plumbing fixture.
How do I fix my rattling pipes in my house?
Here’s how:
- Shut off the water to your home at the main.
- Open the highest faucet in your home.
- Open the lowest faucet (it’s usually outside or in the basement) and let all the water drain out.
- Turn the lowest faucet off (the one you opened in step #3) and turn the water main back on.
Are noisy water pipes dangerous?
When water is running and is then suddenly turned off, the rushing liquid has no place to go and slams against the shut-off valve. The loud, thudding sound that follows is known as a water hammer. Besides being alarming, water hammer can potentially damage joints and connections in the water pipe itself.
What should I do if my pipes are rattling in my house?
Turn on the highest faucet in your house (one that’s the farthest upstairs and furthest away from your main water supply). Turn on the lowest faucet in the house (one in the basement, outside, or located on the first floor closest to your main sewer line).
What’s the best way to get rid of a noisy water pipe?
Shut off your home’s main water supply valve. Open the highest faucet inside your house. Find the lowest faucet on the property — it’s usually on the first floor somewhere outside or in the basement — and turn it on to completely drain all water from the pipes.
What to do when your hot water faucet rattles?
Test both the hot and cold water from the faucet. When you locate the banging pipe, hopefully it will be exposed (like in the basement or crawlspace). Secure the pipe by adding a small piece of foam or rubber pipe insulation to the pipe and re-strap it.
What to do when your water pipes stop working?
Eventually, the water will drain out and stop flowing, allowing air into your pipes. Turn off the low faucet, turn on your main valve, and allow water to re-fill your plumbing until it’s freely flowing through your high faucet again.
