You’ve probably seen rolls of blue and red PEX pipe in your local home improvement store, but did you know that it is rapidly replacing copper and galvanized steel as water supply lines in new construction homes? In fact, this flexible plastic tubing is making it easier for enthusiastic DIYers to replace their own leaky water lines than ever before.
When installing PEX, there are a few important things to keep in mind. One is that although it is more flexible than copper or CPVC, it must be supported properly to prevent failure due to sagging or twisting. Another is that while it can be connected using push fit fittings, it is best to use crimp rings and pinch clamps for new installations. While there are power tools available to make crimp ring connections, these can be difficult to work with in tight spaces.
Lastly, it is crucial that PEX be insulated to protect it from freezing temperatures, especially outdoors. If it is not adequately protected, ice may form inside the tubing which can crack or burst it.
It is also necessary to make sure that any water supply valves within the home are properly insulated. If not, the PEX will expand when the shut off valve is closed which can cause a loud banging sound called water hammer. This can cause damage to the plumbing system and should be addressed as soon as possible. Also, rodents are known to chew through PEX, so it is important to keep an eye out for them around your Los Angeles home and take steps to deter their activity. pex pipe
