Enema Check Flow Valves are inserted into any 1/4" or 5/16" enema tubing. It is an optional item enema users buy to protect their tubing from being re-contaminated if there is ever a back flow suction effect in the enema tubing. The back flow is caused by changing the height in the bucket or gravity pull. The check flow valve will prevent any enema solution going back up from the rectum into the tubing. This will keep your tubing clean and hygienic.
