What Is The Difference Between Red And Blue Pex Tubing?

Color-coding: Red PEX pipes may be used for hot water supply lines, blue PEX pipes can be used for cold water supply lines, and white PEX pipes can be used for either hot or cold water supply lines. These colors are just for the purpose of convenience. The plumbing code does not require that the color of the pipe correspond to the kind of water supply.

The varying colors of PEX do not denote any distinctions between the three varieties of PEX (see Label Lingo, below); rather, they just make it easier for the installer to distinguish which lines carry hot water and which lines carry cold water while installing the system. The hot water is delivered by red PEX tubing. Cold water is delivered through blue PEX pipe.

What color is blue PEX pipe used for?

Cold water is delivered through blue PEX pipe. White PEX pipe may be used for either hot or cold water, depending on the application. Gray PEX pipe, like white PEX tubing, may be used for both hot and cold water applications (although not all DIY centers carry gray). With this in mind, what do the different colors of PEX pipe indicate?

Which is better PEX A or PEX B?

Overall, PEX A is more resistant to burst pressure than PEX B, which is a good thing. As a result of PEX A’s expansive substance, it can withstand pressures of up to 500 PSI, making it dependable even in extremely low conditions. Due to the fact that PEX B is a more stiff polymer, it will not perform as well in similar scenarios.

Which PEX is best?

It is perfect for use with kitchen and bath fixtures since PEX-A is the most flexible tubing available and has the highest freeze- and kink resistance. PEX-B is somewhat less flexible than PEX-A and is less freeze-resistant than PEX-A.

Will PEX pipe freeze and burst?

PEX pipes, like any other type of plumbing, may and will freeze if the temperature becomes sufficiently cold. PEX, on the other hand, may be less susceptible to rupture as a result of freezing. Manufacturers, on the other hand, will not issue a warranty against rupture due to freezing.

How long does PEX pipe last?

What is wrong with PEX plumbing?

Incorrect installation can result in stress on PEX piping due to its maximum bend radius, which can lead to failure of the pipe. Aside from that, excessive bends and kinks create a tremendous amount of local stress on the pipe’s wall, making it more prone to oxidative deterioration as time passes.

Which is better PEX crimp or clamp?

If you want a connection that is both fast and secure, as well as one that will last for a long time, crimp tools are your best options. However, if you want more flexibility without having to work more, PEX clamps are the way to go.
