I can't stop the water because the J pipe is jammed under the lid of the tank. Now after about five gallons of water has shot out of the tank, I finally get the lid lifted and pick up the J pipe to stop the siphon. Water is everywhere, and to make things even better the electrical strips start to short out and smoke. So I start whacking the wall outlet with a small towel and my hand, to try and get the power strips unplugged. Needless to say I got jolted a few times before the plug came lose.
Lets just say it was quite an interesting experience.
When all is said and done the only casualties were a few ceiling tiles and my pride. For the next week I played with the sump every day until 1 in the morning. I finally gave up and removed the sump. Oh well, live and learn.
