Disclosed are various embodiments for an anti-reflux enema bucket system that is leakproof, easy to disassemble and clean, prevents reflux, has components that can be independently cleaned and sanitized, and controls a rate at which water is expelled from a nozzle outlet. In various embodiments, the enema bucket system includes an enema bucket having an opening at a top for filling the enema bucket with solution, a nozzle comprising a nozzle outlet, an anti-reflux coupler positioned between the enema bucket and the nozzle through which the solution passes from the enema bucket to the nozzle outlet； and tubing fluidly coupling the enema bucket, the anti-reflux coupler, and the nozzle. A pulley restrictor may selectively control a speed at which the solution is introduced into the nozzle and expelled from the nozzle outlet.
