we had a house with a sink in the basement that "flushed" up. I thought it was pretty neat until the day I discovered my kid pouring turpentine down it. nothing catastrophic happened, [I suppose modern electric motors are real safe and all, but something didn't quite feel right about pouring that kind of flammable liquid down on an electric motor. my rule became no flammables down the drain. hope yours doesn't use any electricity don, or - hope you have no gas. My Congrats, too. We should start a string about ambisish projects done with PD [I'm still thinking..............]
