Waste Water Dumping Tip
Never leave your black tank valve open when you are hooked up
to a sewer equipped RV site. If left open, the liquids will
drain off and leave the solid material behind to build up in the tank.
Always dump your black tank first and always when it is at least
2/3rd full. Add water if necessary. This will ensure adequate flow
to dump all the contents.
Dump the gray water tank last to help rinse out the valves and sewer
hose.
