I have found too that luke warm water can stimulate them to poop. My first BP and my new baby poop just about every time they are put in luke warm water. I have also found that luke warm water can stimulate feeding also. This can be helpful but at the same time you have to be cautious too. I used to feed a Redtail Boa in a dentist's office and he was a picky eater so sometimes I had to take him to a sink in the back, put a little luke warm water in it, then after a few minutes drop the mouse in and every time he would immediately take the mouse. So far, and I guess I'm lucky, I have not been pooped on or peed on by a snake.
