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.
Its flexibility has other advantages. It can be produced, rolled, and shipped in long lengths. This means it costs less to ship. Because it comes in a long, continuous tube, it does not require a lot of connections to get it to the required length. It takes less time and work to install. The job can get done faster and cost less than using other types of plumbing materials.
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 positive thing about PEX plumbing is that fewer connections means fewer places where the plumbing can develop leaks. This can save the homeowner a lot of hassle and expense down the line. Money is saved on both plumbing repairs, and possible costly repairs of the damage caused by any leaks within the walls or foundation.
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!
