Make sure you let lots of water build up before draining the tank. It will help keep this sort of thing from happening. When I go out on a one/two night trip I add 12- 15 gallons of water to the waste tank before I leave. That way I'm sure there is enough water in there to get everything to break up and flush out easily.
Great advice. You would be surprised how many people leave the dump valve open when connected to hookups. All the liquid drains out while the solids keep piling up. When the tank is full, it is really full (of?)LOL
