How Do You Work With PEX Tubing?
PEX, or crosslinked polyethylene, is a water supply piping system that is becoming more and more common in new construction and remodels. It is being used in lieu of PVC, CPVC, copper or galvanized iron pipe. It doesn’t corrode or develop pinholes and is faster to install with fewer connections and fittings. PEX has no aftermarket and is not attractive to thieves the way copper is. PEX has been in use in Europe since 1970, but only has been in use in the United States since 1980. PEX requires special tools to make the connections, but other than that it is easy to work with PEX tubing. Purchase the three main PEX tools from your local PEX supplier: the PEX pipe cutter, the crimping tool, and the de-crimping tool. Measure the length of PEX tubing you need. Check the allowances of any fittings you will be using to allow for enough overlap to slide the PEX tubing on. Cut the PEX at the adjusted length with the PEX pipe cutter. Make sure the end is cut squarely. Slide the copper crimp ring
