Groco PNC Series Pipe Nipples with Check Valve

PNC Series is offered to simplify plumbing assembly, reduce cost and save space. PNC Series Check Valves can be used to keep a pump primed that is not self priming, on bilge pumps to keep the pump from cycling on and off from water draining back into the sump from the discharge line after the pump shuts off, and are sometimes used in hot water heaters to prevent the heated water from draining back to the tank.
