Purple PEX for reclaimed water
March 1, 2016
PEX tubing for reclaimed water has high rating for chlorine and is available in ½”, ¾” and 1” sizes. PEX tubing for reclaimed water can aid a home in receiving LEED or National Green Building Standard points. Installation of the new tubing alongside other PureFlow solutions is seamless with system-matched tools and jaws. The process of water reclamation varies often after collection water is run through an in-home filtration system, and then is then reused in other areas of the home such as laundry, toilets and irrigation systems. Purple is the standard color of tubing for reclaimed water lines.
