The California Department of Housing and Community Development has incorporated a major change in the California building standard.

The California Department of Housing and Community Development (HCD) has incorporated a major change in the California building standard that now approves postchlorinated polyvinyl chloride (CPVC) plastic pipes for the California Plumbing Code.

According to the HCD's findings, CPVC will give new home construction and existing homeowners a permanent solution to end premature failed metallic pipe by allowing CPVC installation. Its Draft Environmental Impact Report of 1998 said the alternative of requiring the use of CPVC would be "environmentally preferable," since all conditions related to corrosion of potable water piping, including contributions to environmental contamination, would be avoided.

CPVC offers California corrosion resistance for homes, condominiums, buildings and hotels where aggressive water, earthquakes and soil conditions have led to pitting, scaling and breakdowns in other piping materials, causing leaks, water damage and water contamination.
