Performance and endurance
ANSI/ASME A112.18.3M, A112.18.1M
CSA B125

ANSI/ASME A112.18.3M (Performance Requirements for Backflow Protection Devices and Systems in Plumbing Fixture Fittings) is applicable to plumbing fixture fittings with outlets not protected by an air gap. Included in the possible range of applications are fittings with hose connected outlets, fittings with pull-out spout, hand held showers, shampoo fittings and deck-mounted fittings.

The Standard addresses functional performance (water tightness in various backpressure and backsiphonage conditions), mechanical wear (endurance testing of 200,000 cycles) and mineral deposits (hot and cold water tests with a water hardness of 200 to 270 ppm CaCO3).

Check valves listed to ASME A112.18.3M provide a higher degree of reliability throughout the useful life of the fitting and offer an alternative to non-certified vacuum breaker components.

ASME A112.18.3M is now referenced in ASME A112.18.1M (Plumbing Fixture Fittings) and CSA B125 . NEOPERL check valves are listed to both standards with the Canadian Standards Association, IAPMO and UL.

Compatibility with drinking water
ANSI/NSF61

ANSI/NSF61 (Drinking Water System Components - Health Effects) was developed to establish minimum requirements for the control of potential adverse human health effects from products in contact with drinking water. The tests include level of lead and other regulated metals, organic contaminants and solvents.

NEOPERL’ s plants are monitored by UL. NEOPERL^® products are listed and are continually audited and periodically re-tested.

NEOPERL’ s product listing to ANSI/NSF61 is available at www.ul.com.
