PEX, or cross-linked polyethylene, is an increasingly popular choice for plumbing projects in both residential and commercial buildings. This versatile material is strong, durable, and corrosion-resistant, making it an ideal choice for underground water supply and drainage lines.
PEX is also easier to install than traditional copper or galvanized steel pipes, making it a great option for DIY projects. In this article, we’ll discuss the benefits of using underground insulated pex, the proper installation techniques for this type of pipe, and the types of PEX available.
Benefits of PEX
One of the main benefits of using PEX for underground water lines is its durability. PEX is made of a strong cross-linked polyethylene material that is resistant to cracking, rust, corrosion, and freezing. This makes it ideal for underground water lines, as it can withstand the pressure of the earth and other elements. Additionally, PEX is flexible, which makes it easier to install than traditional rigid water pipes. This means less time and money spent on labor, making it a cost-effective option.
Installation
When installing PEX for underground water lines, it’s important to use the proper techniques to ensure the pipe is secure and will last for years. The first step is to prepare the area where the pipe will be installed. This means clearing away any rocks, roots, or debris that could interfere with the installation. Once the area is cleared, the pipe should be laid out in the desired pattern and secured in place with stakes. The pipe should then be connected using PEX fittings and clamps.
Types of PEX
PEX is available in a variety of sizes and types. The most common type is PEX-A, which is made from high-density polyethylene and is the most flexible of all PEX types. PEX-B is also available, but it is not as flexible as PEX-A. PEX-C is the least flexible of the three types, but it is more resistant to corrosion. No matter which type is chosen, all PEX should have a minimum pressure rating of 200 psi to ensure the pipe is strong enough to withstand the pressure from underground water lines.
