Noisy pipes in a building’s plumbing system can be a frustrating issue that can spoil the peace and comfort of a home. When they are working properly, there’s no need to pay them much attention, but as they have to withstand frequent fluctuations in temperature and pressure, water pipes can malfunction, resulting in noisy pipework. There are several potential causes of noisy pipes, which vary depending on the plumbing system, the age and condition of the pipes, and where the noise is coming from. Understanding the cause of noisy pipes can help homeowners to identify and address the issue effectively.
This is a common cause of noisy pipes and occurs when the water flow is stopped abruptly. This causes a sudden change in pressure and a loud hammering noise. There are many factors that can cause water hammer, such as badly secured pipes, high water pressure or fast-closing valves. You can read about water hammer in more detail here: If water hammer is not addressed, it can damage pipes over time. It can be resolved by adjusting the water pressure or installing water hammer arrestors.
Loose pipes cause rattling noises in the plumbing system. Pipes can become loose due to normal wear and tear, improper installation, or movement of the foundations. Loose pipes bang against floors, walls, or other pipes. You can reduce the noise by securing the pipes with pipe straps or clips.
Metal pipework warms up and expands as hot water is transported throughout it to supply home radiators, causing noise. If you install copper pipe in your house, it is worth lowering the temperature of your water heater slightly as this can eradicate the issue so you don’t need to disrupt the entire supply pipe system.
A build-up of sediment can also cause noisy pipes. Minerals and sediment can settle at the bottom of pipes, leading to restricted water flow and increased water pressure, and this results in noisy pipes. You can help prevent sediment build-up by flushing the pipes periodically or by installing filters or water softeners.
