Multi-Port Drain Adapters

This Standard covers plumbing waste fittings of sizes NPS-2 and smaller, not including plumbing supply fittings, other devices, or flexible water connectors under continuous pressure, all of which are covered by separate Standards.

This specification refers to the requirements and test methods associated with the virgin polyvinyl chloride (PVC) construction of plastic drain, waste, and vent pipe and fittings. Covered fittings are subjected to hydrostatic burst pressure and impact-resistance testing.

This specification establishes requirements for dimensions and gaging of taper pipe threads used on threaded plastic pipe and fittings.

This Canadian Standard (harmonized with ASME A112.18.2) has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

NSF/ANSI 61 addresses the human health effects of drinking water system components. This performance-based standard evaluates the amount of contaminants that leach from the products into potable drinking water. The origin for this standard was lead reduction/ removal. Any lead that elutes into the water at over 0.25% fails this standard.

NSF/ANSI 372 establishes a standardized methodology for the determination and verification of product compliance to minimize lead contaminants. This standard is consistent with the United States Safe Drinking Water Act (SDWA) and its lead-free plumbing requirements, as well as the requirements of individual U.S. states such as California.
