I may have this wrong, but if you leave your gray water tank drain valve open, hooked up to the sewer hub and therefore empty, you are inviting the fumes from the park sewer system to back up into your tank & sink drain if you do not have a trap in it, if the trap is not filled with water or if it is working improperly. I leave all drains closed and dump intermittently. Gray water is a good flush of the sewer hose after dumping black water.
