3/4" Brass Dual Check Valve

Dual Check Valve with Vacuum Breaker Vent (3/4" only).
Basepump faded with enhanced DCV VB

Installation of the dual check valve with vacuum breaker vent does the same job as the standard dual check valve, but has the added feature of a vacuum breaker, downstream vent.
This type of Dual Check Valve also contains two internal check valves that only allow water to flow through it in one direction.
Downstream vented vacuum breaker gives added protection as required in some jurisdictions.
Depending on the water pressure, the use of this check valve may reduce the pumping volume slightly
