Citation Gray Tank
My gray tank does not drain out all the way. I was completely level when I emptied it last and when I got to my storage facility and just happened to hook up to flush the system I noticed a good amount of water came out of the gray tank. Probably at least a few gallons. The rig was tilted a bit towards the drain pipe. Could the tank be installed not level and when tilted the right way it completely emptied? The gray tank already fills up too quickly. It might help if it was completely empty.
