Abstract

A sealed drain tool for a pump with a drain has a cylindrical tool housing. The housing has a mounting end for attaching the tool to the pump. The housing also has a free end and a bore extending longitudinally through the housing from the mounting end to the free end. The bore defines an inlet opening at the mounting end for communicating with the drain opening of the pump and has a free and opening at the free end. A plunger is slidably received within the bore. A stop element prevents the plunger from exiting the free end opening. A seal is provided between the plunger and bore adjacent the free end for preventing fluid from exiting the free end opening. A discharge opening in the tool housing permits fluid to pass from the drain of the pump through the inlet opening into the bore of the tool housing and to exit the tool housing through the discharge opening to a suitable container.
