We came up with a new way to clean water tanks. We put an old propane tank on a buggy to hold the water. We attached a used surge vacuum pump that is run by a Honda motor. The pump builds up vacuum in the tank, so we can just open a valve and suck everything out of the waterer into the tank. Once it is full, we have a valve at the bottom of the tank that we open so the water runs out. Instead of taking us a whole day to clean all the water tanks, it now takes us about an hour.
