PEX; short for cross-linked polyethylene has developed into an affordable product of preference for a number of general contractors and plumbers. It has been used in the USA since 1980?s for a lot of installations which include basic plumbing and hydronic floor heating systems.
PEX will never be freeze resistant, but is undoubtedly unlikely to burst especially during unusually cold temperature compared to almost every other type of plumbing. Because of overall flexibility PEX is often installed with a number of configurations as well as having a manifold and plumbing with a continuous home run for the cold and hot lines to each appliance. With this type of application there aren’t any plumbing connectors present to develop into water leaks inside crawl spaces, inside of walls or under cement slabs.
PEX can even be installed by using couplings which can be attached with specific fittings. It can be used as the main service line from your road but it really should be protected inside a sleeve where it is going through your foundation structure directly into the house.
