What is PEX?

PEX piping (shorthand for cross-linked polyethylene) fees much less than half of the charge of copper and installs a whole lot faster. And when you consider that it’s flexible, PEX makes redesigning jobs easier. PEX has a sturdy “memory;” it usually needs to spring again to its authentic shape. So working with a coil of PEX is like wrestling with a massive Slinky. For most jobs, you’re higher off shopping for 10-ft. “sticks” instead. You may additionally have to pay a few cents greater per foot and set up a coupler or two, however you’ll keep away from frustration and kinks. Even plumbers who run miles of PEX each yr regularly purchase sticks than coils.

Types of Pex Pipe

Find out how PEX-A, -B and -C are comparable and how they evaluate when it comes to their software uses, reputation and man or woman advantages.

The three sorts of PEX all share a integral similarity, however they are not precisely the same. Discover the variations amongst PEX-A, -B and -C, inclusive of which functions every one works nice in, how extensively used they are and what their special blessings are.

1. PEX-A

PEX-a is bendy and has if truth be told no coil memory, making it the most in many instances used tubing kind with growth fittings. It can additionally be used with push, crimp, clamp and press fashion fitting; alternatively it is generally the highest-priced PEX pipe type.

2. PEX-B

PEX-B is a clear winner in phrases of charge vs. each different types. It has been in use for over forty years with no regarded issues, given that a common assurance for any kind of PEX is solely 20-25 years. It additionally has a greater bursting stress than PEX-A and a comparable or higher resistance to oxidation - a very necessary thing for plumbing installations.

The important draw back of PEX-B is its’ stiffness and coil reminiscence (tendency to return to the authentic structure of coil). While there’s little distinction in smaller sizes such as 1/2", large pipe diameters, specifically 1", can be especially more difficult to bend. Any kinks (which are very uncommon in our experience, however nevertheless occur) made for the duration of the set up can only be repaired by means of putting in a coupling and can't be repaired with a warmness gun like PEX-A.

3. PEX-C

PEX-C is the stiffest of the three kinds of PEX, making it the most tough to work with. It is inclined to kinking and prone to cracks in freezing conditions. PEX-C is the most inexpensive option, and ought to solely be used for small repairs that don’t require a good deal bending. PEX-C is manufactured by using an irradiation method.

It is one of the most luxurious kinds of PEX tubing and is oftentimes recognised as the PEX with an aluminum barrier. The special issue of this high-end PEX tubing is the introduced aluminum barrier that helps this PEX pipe hold its unique shape.

With this class of PEX pipes, you can have the tubes preserve the structure that you bend them into. PEX AL PEX additionally affords an environment friendly oxygen barrier which skill it can be a wonderful preference to be used in heating systems.

PEX Pipe Advantages

There are many advantages of PEX piping, including:

• Lower fee to install. PEX prices roughly the 1/3 of the charge that copper piping costs. And if you’re searching for whole-home piping in new construction, the price financial savings can truely add up. Also, the fee of copper varies in exceptional markets whilst PEX is much less susceptible to rate changes.
• Corrosion resistance. Unlike galvanized metal pipes and copper piping, PEX is resistant to corrosion, mineral buildup, and erosion.
• Ease of installation. For many minor DIY projects, it doesn’t require a plumbing license to do your very own PEX pipe set up (although there are distinctive tools). For example, one can change historical pipes in a leaky sink. Since PEX is flexible, it lets in for effortless set up in challenging to attain places.

PEX Pipe Disadvantages

• Installation errors. While some humans may also discover PEX set up to be easy, others might also be in over their heads. We advocate leaving pipe set up up to the professionals, in particular if it includes greater shifting parts, strolling traces from different rooms, or in company new construction.
• Heat damage. PEX is inclined to failure in high-heat conditions so it can't be set up without delay to water heaters (although there are connection substances to workaround). It additionally can't be positioned close to recessed lighting.
• UV light. PEX is very touchy to UV light, so it’s vital that all PEX piping be hidden from direct daylight and UV lightbulbs. Many producers suggest complete darkness for PEX pipes so this limits the place it can be installed.
