Reasons Why Water Pipes Are Noisy (And How to Shut Them Up)

Getting unwanted noise from your plumbing pipes can be a major annoyance and can even affect your quality of sleep. Common causes of noisy pipes include water pressure that is too high, improper installation, and air in the pipes. Fortunately, there are a few simple steps you can take to silence your pipes and make your home a quieter place.

Water Hammering

Water hammering is a phenomenon that occurs when a high-velocity fluid, usually water, impacts a closed valve or other obstruction in a pipe. It is a destructive force that can damage pipes, valves, fittings, and other components of a plumbing system. In extreme cases, it can even cause structural damage to buildings.

Water hammering occurs when a sudden change in pressure causes water to move through a pipe at an increased velocity. This can happen when a valve is closed too quickly, or when a pump is shut off suddenly. As the water accelerates, it builds up kinetic energy, which can cause a shockwave when the water reaches a closed valve or other obstruction. This shockwave is what causes the damage.

To prevent water hammering, it is important to maintain the pressure of the water within the pipe system. This can be done by regulating the flow rate of the water, and by installing pressure-relief valves. Pressure-relief valves are designed to open when the pressure in the pipe reaches a certain level, allowing the kinetic energy to be released without causing damage.

It is also important to make sure that the pipe system is properly designed and installed. This means using pipes with the correct diameter, and ensuring that the valves and fittings are installed properly and in the correct locations.

Loose Piping

Loose piping occurs when pipes are not securely held in place, allowing them to move and vibrate. This can cause damage to the pipes and the surrounding structure.

In order to prevent loose piping, it is important to make sure that all pipes are securely attached to the supporting structure. This can be done by using clamps, brackets, or other fastening devices. It is also important to periodically inspect the piping system to make sure that it is properly secured.

Leaking Pipes

Leaking pipes can be caused by a variety of factors, including poor installation, corrosion, and wear and tear. Leaks can be dangerous, as they can lead to water damage, mould, and other issues.

Worn-Out Washers

Worn-out washers can be a major cause of leaking pipes. Washers are small rubber or plastic ring that fits between the two pipes and helps to create a tight seal. If a washer is worn out, it will not be able to create an effective seal, leading to water leakage. 

Worn Out Ballcock Assembly

A ballcock assembly is part of a toilet tank that controls the flow of water into the bowl. If the assembly is worn out, it can cause leaking in the pipes behind the toilet. This is a common problem in older toilets and should be replaced as soon as possible.


Corrosion can occur in pipes when they are exposed to water or other elements, such as oxygen and chlorine. This can cause the pipes to weaken and eventually lead to a leak. Corrosion can be prevented by using corrosion-resistant pipes or by using a corrosion inhibitor.

What to Do about Noisy Water Pipes

Noisy water pipes can be caused by a number of factors, including loose connections, water pressure, and temperature changes. To reduce the noise, try tightening any loose connections and check the water pressure. Additionally, you can insulate the pipes to reduce the effects of temperature changes. If the problem persists, you may need to call a plumber.


It is important to understand what is causing your water pipes to be noisy and address the issue promptly. If you hear any banging or clanging noises coming from your pipes, the most likely culprit is air in the pipes or a water pressure issue. To fix the issue, you should check your water pressure regulator, make sure the pipes are properly sealed, and make sure there is no air trapped in the pipes. If the noise persists, you should contact a professional plumber to assess the situation and make any necessary repairs. With the proper understanding and care, you can ensure your water pipes will remain quiet.
