Question

I have a great big water bag with a tube that would make a great enema bag. I cut the mouthpiece end off but when I fill the bag with water and insert it into my bottom the water cannot move. I assume this is because of the air. If I cut I tiny air hole in both ends (meaning the end in my bottom and the one on the outside) will this fix it? If not, please let me know how. Thanks

If the bag is flexible, there should not be any need for a vent hole. If the bag is above the nozzle, the water should flow unless the tube is blocked. Check that the tube is open from bag to nozzle.

How high above the rectum is it when you do this?

3ft is a good height to start out!

A common issue is the end of the tube being blocked by the rectal wall or fecal material. This is one reason why many rectal catheters have side holes on them, you might want to try to put one or two in.

Also make sure that the cut edges are smooth, as a sharp edge can cause damage. If it's vinyl you can sand it or carefully heat it over a small flame to round it off.

Simple test. Does the water run out the tube when it is not inserted in your rectum? If so, the tube is being blocked like Moliere said from poop or maybe the tube gets kinked inside your rectum. Cutting side exit holes in the tube is a good idea; many colon tubes are designed this way. I have three colon tubes and they all have side exit holes.

You might also try adding a Higginson style inline force bulb to get the Enema running. I buy mine at The Toy Store (Harbor Freight) when they are on sale for only a few dollars.
