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.
Because it is made of a high-density polymer, it is very flexible. This means you can bend it around corners without needing an elbow connector. It is strong also, so there is no need to worry about the tubing crushing or crimping. This flexibility is one of the main reasons it is such a popular choice for radiant heat floor installations.
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.
There is also an environmental advantage to using this type of tubing. Other types of plumbing require acidic flux and lead solder to make the connections. PEX pipe does not require any flux or solder, so there is no toxic chemicals or lead leached into the water or soil. There is also minimal heat loss with this tubing, which conserves energy.
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.
