Designed for installation in waste discharge and bilge pumpout systems. When installed, the waste can be pumped directly into a holding tank or, when legal, diverted to an overboard discharge fitting. The valve is supplied with a stainless steel locking ring that allows the lever to be locked in the holding tank position when operating in no-discharge zones. When used for bilge pumping, two separate bilge sections can be emptied with a single pump. All polyester and stainless steel construction will withstand corrosive waste chemicals and bilge water. • Self cleaning design provides trouble free operation • Molded in flow direction indicator arrows • Valve is supplied with three 1-1/2" (38 mm) ports, and an extra 1" (25 mm) straight inlet port for connection to macerating toilets • Rotating ports allow flexibility in hose routing to the valve • Lift-away top provides for easy maintenance • Lock not included
