The smart way to handle gray water, this Sump/Pump Combo enables you to plumb all gray water hoses to one location. With eight inlet ports, each with two different dimensions permuting a variety of hose sizes to be connected, the Gulper Shower Drain Kit provides convenient versatility on your boat. This Sump/Pump Combo includes an automatic float switch that activates a Gulper 220 pump which pumps gray water to one location—either a holding tank or overboard. Now you can reduce the number of gray water thru-hull fittings to just one.
