Why You Should Select PEX Tubing


February 18, 2010

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 is also better for the environment than traditional options. Rigid plumbing requires acidic materials or lead solder to make necessary connections. This introduces dangerous chemicals into the soil and water. PEX pipe requires no chemicals to create connections. Another advantage is that there is reduced heat loss with this type of tubing. Reduced heat loss translates into less energy consumption.

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.

Because polymer tubing like this allows a small amount of oxygen to escape through the material, you will need a special kind of tubing for radiant heat floors. This is because the flooring material can react with the oxygen and cause corrosion of the floor. There are a couple oxygen-barrier types of PEX plumbing materials on the market. Be sure your contractor is using one of these types for any flooring or walkways.

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.
