PEX plumbing and chlorine do not mix well, which is ironic. Chlorination badly affects the durability of the PEX plumbing system and shortens its lifespan. The chlorine in the water inside PEX pipes speed-up the brittle oxidative failure of cross-linked polyethylene. This failure leads to sudden leakage and sometimes even bursting of the pipes.
To combat this failure, manufacturers began to add antioxidants into the PEX piping. However, it only ended up delaying the oxidation to a slight degree. Now, the chlorine degrades the antioxidants first but eventually ends up reaching the pipe and causing failure. PEX plumbing lacks versatility because of its sensitivity to light. PEX cannot be taken anywhere outside the house where it is directly exposed to UV for a long period.
The synthetic material of the pipes can slowly disintegrate due to the light of the sun. Even light bulbs have been known to affect the lifespan of PEX water lines. While this is a rare failure, it still happens. Under unique circumstances, PEX water lines become highly susceptible to bacteria.
This mostly happens when PEX pipes are installed deep under the ground and vulnerable to moisture. In extreme cases, the bacteria caused by moisture can penetrate inside the PEX pipes and contaminate the water. As is the case with most plastics, PEX pipes are also non-recyclable. Wirsbo is the best IMO.
The fiitings are the same ID as the tubing tubing is expanded to recieve fittings so pressure loss is minimal. A manifold system will out perform the old trunk and branch system and remote manifold with recirc line works great in the sq ft, 6 bath homes. Tub and shower valve body supplis are usally fabbed in copper to make a more solid instal.
The freeze resistant qualities of pex are a bonus up here. Pex is far superior to Poly B. The big problem with Poly b was incompetent installers. I installed s of systems including radiant heating using poly B and had not one failure, most systems are still in use today.
Funny how you guys in the USA had s of failures and lawsuits? All were related to improper installation procedures rather than the materials. Unconfirmed estimates are that about , homes in Alberta have Poly-B water systems. You will never expand your mind, if you do not challenge your beliefs.

And of course dezincification in some aspects. As much as I dislike anything new until and I won't buy the EU UK theory that it works there, it should work here buy line, They don't have chlorine levels like we do it has a proven track history, especially from the service perspective.
I can see a bundle wrap of home runs in chicken bracketed soffett that a carpenter shot a nail through the wood You've got limited space to cut out and replace the section, the piping is hard as a freaking rock and won't conform to the barbs of the fittings you're installing and the instant use of heat on plastic ages it considerably causing the piping to be almost like glass in physical properties when its old. Use PB, Blue-Max, CPVC for reference to the aging process of plastic products when consistently subjected to temperature variances over the life span of the product, short few years, just a year in most cases.
Never had a problem with copper pipe growing 2" over '. Never had a underground water service in copper constantly snap because it was stretched from end to end and not snaked in the ditch to allow such movement. Not all applications will require this method but I'm considering the option since all is exposed and suits the need on a entirely different level not implicating plumbing and its design. Rodent are a problem for sure not only pex but for all types of piping in he cieling.
Had them eat ABS drain piping too. LOL bad luck for the owner, but i think its time to call the xterminator. Jones Mechanicals. This results in blockage within the fitting, reduced water flow, and leaks. When the zinc leaches from the fitting, the resulting copper becomes porous and weak, which leads to fitting leaks and damage.
Most water in the U. It has been found that chlorine can cause oxidation on the inner wall of PEX piping, eventually resulting in failure. As with any plastic pipe, ultraviolet UV light can break down the stabilizers in PEX, causing the pipe to become brittle and eventually fail.
Overexposure to sunlight prior to installation can result in pipe failure. Most PEX manufacturers allow no more than 60 days of sunlight exposure for normal PEX piping and no more than six months for PEX piping with ultraviolet stabilizers added during manufacturing. Studies have shown a dramatic reduction of chlorine resistance after even one week of direct sun exposure. PEX should not be used in exterior settings or in locations exposed to sunlight.
Exposing PEX to certain petroleum products and oxygen increases the permeability of the piping.
