Liquid waste disposal and canister flushing system and method

A flush jet usable with a liquid waste disposal and canister flushing system, said flushing system including a cabinet including a subsink accommodating a canister to be flushed, the canister including an accessory port for accommodating the flush jet, said flush jet comprising:

• (a) a body with upper and lower ends;
• (b) a cleaning solution inlet port at said upper end;
• (c) a water inlet port at said upper end;
• (d) a discharge orifice at said lower end;
• (e) a jet passage extending from said water inlet port to said discharge orifice;
• and
• (f) a cleaning solution passage extending from said cleaning solution inlet port to said jet passage and forming an intersection therewith at an angle which eliminates any venturi effect on said cleaning solution passage from said jet passage.

A control system for a liquid waste disposal and canister flushing system, said flushing system including a flush jet attached to a source of water and a source of cleaning solution, said flush jet being designed for insertion in a canister to be flushed and a cabinet including a subsink for holding the canister during flushing, said system comprising:

• (a) a programmed controller programmed to control drain and flush cycles of said system;
• (b) a water flow monitor connected to said controller;
• (c) a water pressure monitor connected to said controller;
• (d) a cleaning solution flow monitor connected to said controller;
• and
• (e) flow controllers connected to said source of water and said source of cleaning fluid, and to said controller such that said controller can accurately control the relative concentrations of cleaning fluid to water based upon feedback from said water and cleaning solution flow monitors.

A liquid waste disposal and canister flushing system, said flushing system including:

• (a) a flush jet attached to a source of water and a source of cleaning solution;
• (b) a semi-rigid canister to be flushed, said canister including an upper accessory port which accommodates the insertion of said flush jet and a drain opening for draining the contents of said canister;
• (c) a cabinet including a sink with a floor;
• and
• (d) a subsink which is sized to hold the canister during flushing, said subsink including a basin with a bottom surface which extends below the floor of said cabinet with a subsink drain opening in said basin bottom surface connecting with a sewer system for draining the contents of said subsink, said subsink also including an upwardly extending perimeter wall which extends above the floor of said sink to support said semi-rigid canister.
