You are one lucky person. My husband tried that extension thing and I raised hell as I didn't want the water that high up the bank. I told him to wait until water was down to take the pipe off but no, he too, took the 18" pipe off (from the bank). I was so worried he would try what you did and people forget just how powerful water force can be. I'm glad you listed this in the thread...people need to know, it is very, very dangerous.
