Which PEX pipe is the best?

PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures. PEX-B is slightly less flexible and less freeze-resistant. Both types of tubing come in three colors—red, white, and blue—in diameters ranging from 1/4-inch to 3 inches.

Then, are there different grades of PEX pipe?

There are three different types of PEX tubing: PEX-a, PEX-b and PEX-c. Uponor manufactures PEX-a tubing, which is considered the superior type of PEX in the industry because the crosslinking is done during the manufacturing process when polyethylene is in its amorphic state (above the crystalline melting point).

Also Know, which is better PVC or PEX? When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won't corrode. When you compare the material costs of PEX vs PVC, PEX comes out more expensive. (However, balance this factor against the lower labor cost to install PEX.)

One may also ask, should I use PEX A or PEX B?

PEX-A is the most flexible of all PEX tubing types, has little or no coil memory and gives installer an ability to repair kinks with a heat gun. First and foremost is a high rate of chemical leaching – from 50% to over 200% higher than PEX-B (2), which is a major concern for plumbing applications.

Why is PEX plumbing bad?

PEX plumbing system has been used for more years and therefore its failures has been observed and known. Its major failures is linked to piping and fitting. Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation.
