Water Pipe Noise When Water Is Not Running? (Possible Causes & Fixes)

Random unwanted sounds can really take away from an otherwise relaxing afternoon at home. Sometimes these unwanted sounds can even come from our houses themselves. Water pipes can make a variety of unwanted sounds when they are not operating properly. These pipes can even make noise when the water is not running.

Water hammers occur when water pressure tries to escape pipes but makes a banging sound in the pipe instead. Loose pipes and excessively high water pressure are also common reasons your pipes make noise when the water is not running. Make sure your ballcock assembly and main shut-off valve are working properly. If you can not find the source of the noise you should call a professional.

When you hear a loud banging sound in your pies this could be a phenomenon known as “water hammers.” Water hammers often occur when high-pressure water is shut off too quickly. When the high pressure has nowhere to go after the faucet shuts off the pressure needs to find a place to go.

This pressure with nowhere to go results in loud banging sounds within the pipes, which are also known as water hammers. Normally there is an air duct chamber within the pipes where the water can go. Sometimes this vertical chamber dissipates over time and leaves the high-pressure water with nowhere to go.

Another potential reason for your water pipes making noise when that water is not turned on is excessive water pressure. When the water pressure is high (above 75 psi) the pressure is considered dangerously high. This high pressure can cause your pipes to vibrate and make noises even when the water is not running.

A threaded water gauge is the best and easiest way to confirm if the water pressure is too high. You can screw in the threaded water gauge to a faucet. If the gauge reads about 75 psi you know your pressure needs to be lowered.

If the water pipe noise seems to happen at random times, you may have a problem with sediment in the water heater. The banging noise occurs when bubbles of steam break through the deposit on the bottom.

If this is the source of the noise, you may have a problem with the water heater. If the problem with your water heater persists it may be time to purchase a new one. You can help prevent this issue by regularly flushing your water heater.

It is possible to test many problems yourself. There are several simple things you can listen for or check for to diagnose why your pipes are making noise and the water is not running. When it comes to repairing the problem however, it is often best to consult the professionals.

Sometimes when you hear a water pipe sound when there is no water running it is a sign of a larger problem. When you call a plumber they can investigate the inner-workings of your pipes. You may need new pipes, or need a leak fixed. Identifying these problems early will save you a great deal of money and headache in the long run.

Water pipes can make a variety of sounds for several different reasons. The one thing they have in common is that they are irritating and should be silenced as soon as possible. The sound you hear in the walls or in a water-connected appliance may be the first sign of a bigger issue.

One of the most common water pipe sounds is known as a “water hammer.” These can usually be fixed easily. Your home may suffer from loose or old pipes or washers. The problem may not even be the pipes themselves.

Sometimes your appliances like a water heater or toilet are the source of these annoying sounds. On occasion you can fix these issues yourself. If anything seems more involved than you are comfortable with you should contact a professional. Regardless of how you fix the problem, just make sure you do not ignore it.
