5 Common Causes and Simple Solutions to Noisy Pipes

Noisy pipes can undoubtedly be a nuisance. From subtle trickling sounds to aggressive hammering, these disruptions can cause sleepless nights and constant irritation for homeowners. However, it is essential to note that noisy pipes can also indicate underlying issues in your plumbing system that require attention. This article will explore the common causes of noisy pipes and discuss common-sense solutions to restore peace and tranquillity to your home.

Water Hammer 

A water hammer is a common plumbing problem when water suddenly changes direction or comes to a halt, causing a loud banging or hammering noise in the pipes. It can be caused by quickly turning off a faucet or appliance, such as a washing machine or dishwasher. The sudden water flow stop creates a shockwave in the pipes, resulting in the familiar hammering sound.

Solution: Installing water hammer arrestors or pressure-reducing valves can help mitigate the impact of the water hammer. These devices absorb the shockwave created by the sudden stop of water flow, thereby reducing the noise. Properly securing loose pipes to wall studs or floor joists can also help prevent water hammer.

High Water Pressure

High water pressure can cause noisy pipes, as the force of the water moving through the pipes can lead to vibrations and stress on the pipe joints. Over time, this can cause damage to your plumbing system and lead to leaks or other issues.

Solution: A water pressure regulator can be installed on your main water line to reduce the pressure to a safe and acceptable level. Most residential homes should maintain a water pressure between 40 to 60 psi (pounds per square inch). You can also consult a plumber to assess the water pressure in your home and recommend appropriate solutions.

Thermal Expansion

As the water heats up, it expands, leading to creaking or cracking noises in your pipes. It is common in homes with hot water heating systems or water heaters. The expanding water causes the lines to move and rub against each other or surrounding materials, resulting in noise.

Solution: Installing pipe insulation can help reduce the noise caused by thermal expansion. Additionally, installing expansion tanks in your hot water heating system or near your water heater can alleviate the pressure caused by thermal expansion, reducing the likelihood of noisy pipes.

Loose Pipes

Loose pipes can vibrate and knock against each other or surrounding materials, leading to various noises. It is often the result of improper installation or missing pipe brackets and hangers.


  1. Inspect your plumbing system for loose or improperly secured pipes.
  2. Use pipe brackets or hangers to secure them in place if you find any.
  3. Use the appropriate type and size of brackets or hangers for your specific pipe material to ensure a secure fit.

Air in Pipes

Air trapped in pipes can cause a range of noises, including gurgling, whistling, or clicking sounds. It is often due to air being introduced into the system through a leak or a faulty valve.

Solution: To remove air from your pipes, try turning off your main water supply and opening all the faucets in your home. Once the water has drained from the lines, turn the water supply back on and allow the faucets to run until all air has been expelled. If the problem persists, you may need to call a plumber to identify and address any potential leaks or valve issues.


While noisy pipes can be an annoyance, they can also serve as a helpful warning sign of potential plumbing issues. By understanding the common causes of noisy pipes and implementing the simple solutions discussed in this blog section, you can effectively silence your pipes and ensure your plumbing system’s health and longevity. If you continue to experience noisy pipes after trying these solutions, consult a professional plumber for further assessment and assistance.
