During our October 2021 seminar in Stockport, New York we came across a couple of spring clamps being used to hold a dump tank drain in place during a water supply drill. Nothing fancy to see here....just a simple use of a couple of simple clamps to address a somewhat common issue with dump tank drains. The clamps worked quite well...especially with the drain sleeve on the inside of the tank. The water pressure kept the sleeve against the tank wall and the clamps kept the edge of the drain sleeve draped over the tank frame.
