Watts LFN9-CD 3/4" GHT Double Check Backflow Preventer Field Testable

More About the LFN9-CD:
Watts LFN9-CD Specs
Watts Series LFN9-CD is designed to prevent high hazard back-siphonage back-flow and low-head back pressure (10ft. or less) from contaminating the potable water supply. The LFN9-CD is ideally suited to prevent backflow associated with hose connections and may be screwed directly to the sill cock, yard hydrant or wall hydrant. Typical installations include service sinks, chemical dispensers, sill cocks and frost proof hydrants. Maximum Working Pressure: 125psi (8.6 bar).
Watts LFN9-CD features include two independently operating rubber and stainless steel check valves with an atmospheric vent located between the check valves. In the event of fouling of the downstream check valve, leakage would be vented to atmosphere, thereby, providing a visual indication of failure. The integrity of the check valves can also be verified by performing the field test procedure included with the LFN9-CD. The LFN9- CD features Lead Free* construction to comply with the Lead Free installation requirements.
