PEX Plumbing is the future of the plumbing industry. PEX Plumbing involves PEX tubing, PEX fittings, PEX manifolds or Plumbing Manifolds, and the PEX Tools that accompany these parts

Now you're probably wondering what PEX piping is. Well, it is cross-linked polyethylene pipe. After going through several processes, the material becomes durable for extreme temperatures (hot or cold), creep deformation which happens from long-term exposure to stress, and chemical attack from acids, alkalies and the like.

All of this makes PEX an excellent piping substance for hot and cold water systems, especially since PEX is flexible and well adapted for temperatures below freezing all the way up to 200 degrees Fahrenheit. 

The same PEX is also used for radiant in-floor heating using your tankless hot water heater to heat your house.  You can save money and use the same water heater you use for hot water and get double duty out of it. New high-efficiency water heaters are available that are powerful enough to provide both space heat and domestic hot water.  Go one step further in saving on your utility bills with connecting solar hot water tubes to your in heating system.

This Design Guide Residential PEX Water Supply Plumbing Systems provides the information and resources necessary to design and install cross-linked polyethylene (PEX) water supply systems in residential buildings. It includes comprehensive design concepts and installation guidelines to increase the acceptance and proper use of PEX.
