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.
PEX plumbing is also a money-saving option. Every time you introduce a connection into a plumbing system, it creates the chances of a leak. Fewer connections means lower risk of leaks later on. This will save you repair costs to the plumbing and also costs to repair any secondary damaged caused by those leaks.
If you plan to use PEX for radiant heat flooring applications, there is something to be aware of. Materials in the flooring can begin to corrode when exposed to oxygen. For this reason there is a special kind of oxygen-barrier PEX that is recommended for use with flooring. Check with your contractor to be sure they are using the correct type.
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.
