PEX tubing is back in the California Plumbing Code after the California Building Standards Commission repealed the inclusion of PEX in thestate code, effective Jul. 1 to comply with a court order. 
   The reinstatement removes the state’s amendment that excluded the use of PEX for water piping systems from the 2007 CPC and amends the 2010 CPC.

   The regulations include mitigation measures identified in the commission’s Second Revised Draft Environmental Impact Report and additional conditions and restrictions on the use of PEX.

   The commission’s action allows the use of PEX in all occupancies, including commercial, residential and institutional building construction, rehabilitation and repair under the jurisdiction of the CBSC and responsible agencies in all areas of California.

   The effective date of the action was Aug. 18 for the 2007 CPC and Jan. 1, 2011, for the 2010 CPC.
