PEX tubing has many advantages over copper, lead, PVC plastic, and iron pipes. It is quickly starting to replace other piping in plumbing applications. If you are installing radiant heat flooring, building or remodeling your home, or upgrading your current plumbing, you will probably see this type of tubing used.
It is made from a high-density polymer. This makes it very flexible. This flexibility means that it can be bent around corners without crushing it, and without the need for for a right angle connection. Its ability to bend without needing connectors is what makes it a top choice for radiant heat flooring.
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.
As you can see, this tubing is something worth investigating. The chances are very good that PEX tubing will be less expensive than traditional rigid piping, both in initial costs and installation costs. Plus, you will avoid costly repairs years later. It is definitely worth considering for your next construction project!
