PEX tubing is rapidly beginning to replace all other types of plumbing materials in new construction. This is because it has many huge advantages over traditional materials. If you are planning to build or remodel, install radiant heat floors, or upgrade your current plumbing, you will probably come across this type of tubing.
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.
The incredible flexibility of this product has many advantages. It takes far less time and effort to install, which means your project will get done more quickly and cost less than if you used traditional plumbing pipes. It can also be made in a long, continuous roll, much like a hose. This makes it less expensive to produce and ship. The savings will be passed on to the consumer.
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 make sure to check on the possibility of using PEX tubing for your next project. It will most likely be less expensive in the short term. It will definitely less expensive in the long run!
