PEX is a leading contender for use in plumbing and heating projects, proving to be more affordable and more versatile than copper pipe. However, when PEX is used in outdoor applications, keep in mind that it cannot be used for outdoor aboveground purposes. In fact, the tubing should always be kept out of sunlight. Prior to installation, store PEX indoors or in the original packaging. Exposure lasting as little as 30 days will cause the PEX to degrade in quality and lose its effectiveness.
