What the Heck is Pex

February 5th, 2011 · No Comments

Dear Mr. Home Inspector

 We intend to begin construction with a brand-new home this year and my builder told me he installed PEX inside the past 5 houses he constructed and advised we use it. Would you give us some information when it comes to plumbing the new house with PEX?

Dear Donna and Jim

PEX; short for cross-linked polyethylene has turned into an affordable product of choice for many building contractors and plumbers. This has been used in the United States since the 1980’s for a lot of purposes such as basic plumbing and even hydronic floor heating systems.

 PEX isn’t freeze proof, but is undoubtedly less likely to break especially during unusually cold weather when compared with almost every other type of plumbing. Because of its overall flexibility PEX might be installed in quite a few configurations as well as having a manifold and plumbing a continuing home run for the cold and hot lines to each and every appliance. Using this type of application there aren’t any plumbing connectors present to lead to leaks inside crawl spaces, within walls or beneath concrete foundations.

 PEX can certainly be installed with couplings which can be interconnected with unique fittings. You can use it as the main service line from your street but it should be shielded inside of a sleeve where it is going through your foundation structure into the house.

PEX is distributed in most basic plumbing measurements and you can purchase it color coded; red plumbing for any of the hot lines in addition to blue for the cold water lines. There are numerous positive attributes however there are a few items you need to understand involving installation.

You should not put it in direct sunlight also, you should think about thermal expansion which is seen as sagging anywhere between plumbing hangers which require installation of more hangers.

There are not many build-it-yourself home-owners working with PEX considering that it requires some different tools pertaining to installation; however it is growing to be very popular in remodels as well as upgrades of existing homes.

Being a professional home inspector we don’t see many problems concerning this particular product. We’re finding a large amount of home owners are experiencing very good results and would recommend it to anybody building a brand new house.
