Do plumbers use PEX?

3 plumbers! Cross-linked polyethylene flexible tubing — commonly called PEX — has grown in popularity for residential plumbing over the past decade as an alternative to traditional copper and chlorinated polyvinyl chloride (CPVC) piping.

Is PEX better than PVC?

When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won’t corrode. … It’s resistant to freezing (once again, due to its flexibility, which allows the PEX piping’s diameter to expand as the water pressure changes).

What is the lifespan of PEX pipe?

40-50 years

Should I use PEX-A or PEX B?

Flexibility – PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEXB pipe. Kink-Resistance – PEX-A has the greatest resistance, PEXB the lowest.

Is PEX OK to run underground?

PEX tubing is approved for direct burial outdoors, a practice most often necessary when running a water supply line to a house. PEX, since it can expand, resists freezing more effectively than rigid pipe, but PEX can still burst if water freezes in a line. … Embedding PEX in sand protects it from any rocks in the soil.

Is PEX as good as copper?

Copper Pipe Lifespan. PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping.

Does PEX plumbing cause cancer?

They found that each type caused odors exceeding the Environmental Protection Agency’s guidelines, and leached chemicals such as toluene, which is neurotoxic, and MTBE, a carcinogen that’s been banned as a gasoline additive, but is a byproduct produced during PEX pipe manufacture.

Is PEX crimp or clamp better?

Crimping and clamping create equally reliable seals that will not leak when performed properly. … Stainless steel clamp rings resist corrosion more effectively than copper crimp rings, which can be a major benefit in direct-burial applications. PEX clamps also tend to be easier to remove.

What is the difference between Type A and Type C PEX?

PEX-A tubing is produced using Peroxide (or, “Engel”) method, named after the inventor Tomas Engel. … This type of PEX is probably the most common and is manufactured by a large number of companies. PEXC pipe is manufactured using “Electronic Irradiation” method of cross-linking, also known as “Cold” cross-linking.

Is a PEX manifold worth it?

PEX Plumbing Manifold Benefits Flexible PEX piping is a better insulator than copper and is not susceptible to rust. Manifold systems cut energy losses as hot water arrives faster at the tap, especially when a loop or ring is added to the system.
