Model 1900 Stainless Steel Pitcher Pump has an option called a Drain Back Feature. This feature allows you to drain water that is between the foot valve and the piston for winterizing purposes. The feature is an integral component of the pump’s base. It functions by depressing a pin using the handle. During routine maintenance, the O-rings around this pin feature need to be replaced. A Drain Pin Removal Tool is required to access the Drain Pin. It is a 15” long T handle tool with a special rubberized socket that can pick up the Drain Pin.
