If you plan on remodeling your home, doing new construction, upgrading your existing plumbing system, or installing a radiant heat floor, you will want to check on the possibility of using PEX tubing for your project. It should not be hard to find. PEX plumbing materials are rapidly replacing other materials like lead, copper, iron, and PVC pipes. This is because it has many advantages over the products traditionally used in plumbing.
It is manufactured from a high-density polymer, which is incredibly strong and flexible. This is why it is so popular for use with radiant heat flooring. It can be bent at right angles without needing a elbow connector. It also resists crushing and crimping. You can see how this flexibility would make it preferable to rigid pipes for almost any application.
There are other advantages to its flexible nature. Because it can be make in a continuous roll, it costs less to produce, store and ship. The installation job itself also will cost less because there are few connections. This means less labor and less time to get it installed.
PEX tubing has several environmental advantages. It conserves energy by minimizing heat lost through the material. Plus, other types of plumbing requires the use of solder and flux to make the necessary connections. This leaches lead and acids into the water and and surrounding soil. The fact that PEX pipe requires no flux or solder means there are no dangerous chemicals introduced into the environment.
Another money-saving aspect of PEX plumbing is that it prevents expensive repairs later on. Any time you have to add a connection to a plumbing system, you introduce the possibility of a leak. The cost of repairs to both the plumbing and the secondary damage to floors, walls and the foundation can be huge. The minimal connections required with PEX means lower probability of these problems down the line.
If you are considering radiant heat flooring there is something to note. You will need a special kind of PEX that has an oxygen barrier property. Some materials in flooring can corrode with exposure to oxygen, so a variation of tubing was created to eliminate this problem. Be sure your contractor is using an oxygen-barrier PEX for any walkway or floor applications.
So for your next construction project, definitely look into the advantages of PEX tubing. Chances are it will be less expensive, both to purchase and install, than rigid pipes. You will also greatly reduce the risk of costly problems later on.
