How it Works


The Angel of Water® (Surround) Colon Irrigation System is a very simple, safe, comfortable, and hygienic way to irrigate the colon for endoscopic, radiological, or other medical purposes. The following sequence of events briefly describes the colon irrigation procedure.

The Process


1. Hydration
2. Activation
3. Evacuation

The tank is filled with hot and cold water controlled by a water mixing valve on the basin right topside. The proper temperature of the water falls between 99 -103 degrees F and is monitored by the temperature gauge visible on the front of the tower cabinet. If at any time the water rises above 103 degrees Fahrenheit, the temperature sensor will trigger the flow valve to shut off, stopping water flow to the client.

After the client has comfortably positioned themselves on the basin (with the pillow and cushioned backrest in place) and inserted the nozzle into the rectum, water flow can be activated by turning ON the FLOW switch. Water flow can be stopped at any time by simply turning the FLOW switch OFF. The tank line to the basin nipple has a backflow prevention valve as a permanent plumbing safety feature. It is located underneath the fiberglass basin and is connected directly to the basin nipple through an opening in the basin wall. It prevents water from flowing back into the line once it has passed through the basin nipple into the nozzle and into the client’s rectum.

The system utilizes the controlled pressure created by gravity as water exits the elevated tank in the tower cabinet as activated by the FLOW switch. The procedure can be stopped at any time by simply turning off the FLOW switch to stop the gravity-fed stream of water or by the person simply sliding back off the nozzle and resting on the basin.

A typical colon irrigation session lasts approximately 30-40 minutes and uses approximately 8 gallons of water, which is the total volume capacity of the main tank. Usually, only one tank full of water is needed. At the end of the session, all three switches (U.V., CYCLE, FLOW) are turned OFF and the client slides back off the nozzle so that it naturally drops away from the body. The client can now drain comfortably on the ergonomic basin, sitting up erect or leaning back in a lounge position to fully drain the colon. After this is done, the client can rinse off using the basin sprayer and its control valve located on the basin left topside. Tempered water is delivered to the sprayer by the same water mixing valve on the right topside of the basin that also sends water to the system tank. The client can then towel dry before dressing and leaving the privacy of the colon irrigation room.
