A trans-anal irrigation (TAI) device has a pump base unit, an irrigation fluid reservoir, a wireless electronic controller, fluid tubing, and a disposable rectal catheter in fluid communication with the tubing. The rectal catheter has a retention balloon and a waste control valve. The fluid tubing contains two or three separate lumens for irrigation fluid and retention balloon inflation/deflation and optionally for waste control valve actuation. None of the lumens ever communicates with any other lumen. A hydraulic control circuit has a pump that pumps in one direction only but, with suitable control valves, is able to pump water to and from the retention balloon and to and from an optional waste control valve. A water temperature sensor is mounted in the pump base unit at a thin-wall section. The temperature sensor sends a signal to a controller which provides an indication of whether the water temperature is suitable for use.
