ABSTRACT:
An accessory adapted to be attached to the drain opening of a sink of a parts washer including an upright tubular housing, having a plurality of drain ports at a lower end thereof. A stopper is selectively movable in said housing from a first position above the drain ports to a second position below the ports by the application of force to a shaft operatively coupled thereto. In the first position of the stopper, drainage of fluid from the sink occurs through the drainage port and the drain outlet. In the second position, fluid is blocked from egress through the drain port and the drain opening of the sink and collects in the sink to a predetermined level whereby a series of overflow drain ports drain excess fluid to maintain a constant level of solvent. The shaft is coupled to a spring urging the stopper to the first position when a force is removed from the shaft.
