ABSTRACT:
A liquid waste disposal and canister flushing system includes a cabinet with a sink for receiving the canister and a subsink for receiving a lower portion thereof. The subsink is connected to a drain line. A plunger subassembly includes a stopper which functions as a drain valve for the canister. An injection jet is connected to water and cleaning solution sources and discharges diluted cleaning solution into the canister for flushing same. The injection jet engages the plunger subassembly for ejecting the stopper from a canister drain opening. A control system includes a programmable microprocessor which can be programmed to provide drain and flush cycles of predetermined duration. A method of liquid waste disposal and canister flushing utilizes the microprocessor for delaying the flush cycle until completion of the drain cycle. The control system can provide drain and flush cycles of predetermined durations, can monitor water pressure, flow rate and temperature, cleaning solution flow rate and other system parameters.
