What is PEX piping, and how does it work?
PEX (Cross-Linked Polyethylene) piping is a type of flexible plastic piping used for plumbing and hydronic heating systems. It is made from a network of polyethylene molecules that are cross-linked to create a strong and durable material. PEX piping works by allowing water to flow through its flexible tubes, which can be bent and shaped to fit around corners and obstacles. This flexibility makes PEX piping easier to install and more resistant to freezing and corrosion than traditional copper piping.
PEX piping is also designed to be quieter than traditional piping systems. The flexible material helps to reduce the noise of water flowing through the pipes, making it a popular choice for residential and commercial plumbing applications. Additionally, PEX piping is resistant to scaling and corrosion, which can help to reduce the risk of leaks and other plumbing problems.
Does PEX piping make noise, and if so, why?
While PEX piping is designed to be quieter than traditional piping systems, it is not completely noise-free. Some homeowners may experience noise from their PEX piping, particularly when the system is first turned on or when the water is flowing at high pressure. This noise is usually caused by the water flowing through the pipes and can be described as a hissing, gurgling, or banging sound.
There are several reasons why PEX piping may make noise. One common cause is the expansion and contraction of the pipes as the water flows through them. This expansion and contraction can cause the pipes to vibrate and make noise. Another cause of noise is the presence of air in the pipes, which can cause the water to flow unevenly and create noise. In some cases, the noise may be caused by a problem with the piping system, such as a blockage or a leak.
What are the common types of noise associated with PEX piping?
There are several types of noise that can be associated with PEX piping. One common type of noise is a hissing or whistling sound, which is usually caused by the water flowing through a narrow or restricted section of pipe. Another type of noise is a gurgling or bubbling sound, which is usually caused by the presence of air in the pipes. In some cases, the noise may be a banging or clanging sound, which is usually caused by the pipes expanding and contracting as the water flows through them.
It’s worth noting that not all noise associated with PEX piping is a cause for concern. In many cases, the noise is simply a result of the normal operation of the piping system. However, if the noise is loud or persistent, it may be worth investigating to determine the cause and ensure that the piping system is functioning properly.
How can I reduce the noise associated with PEX piping?
