Order an additional enema stopper. It depends on the stopper with what force and pressure the enema fluid will penetrate the colon. The enema stopper has 5 levels of operation. When closed, it serves as a barrier to the liquid and it cannot continue to flow. When open to the middle, the liquid enters with normal force and pressure. When the stopper is in the middle position, the enema fluid does not enter too strongly and quickly, or too weakly and slowly. When the stopper is open - the liquid from the irrigator enters with the greatest force and pressure.
