After a six-week summer vacation, PEX is back in the California Plumbing Code. The flexible plastic water-supply tubing earned code approval in 2009, after years of resistance from the pipe trades, but a subsequent challenge from The Center for Environmental Health culminated in a court order withdrawing that earlier approval as of July. In mid-August, a revised environmental-impact report was approved by the California Building Standards Commission (CBSC), and code approval was restored. At the same time, a settlement agreement was reached between the CBSC, the Center for Environmental Health, and the Plastic Pipe and Fittings Association, in which the parties agreed to refrain from further legal action.
