Why do my gray tanks smell worse than my black tank sometimes?

For one thing, no current RV manufacturer includes an in-tank rinsing system for their gray tanks like there is in the black tank. This lack of a rinsing process means that waste only leaves the tank when it is emptied. Many RV owners leave gray tank valves open all the time, further promoting the lack of complete tank emptying (waste mounds up or is left behind and begins the process of decomposition).

Additionally, a lot of RV owners do not add any sort of tank additive to their gray tanks, thinking incorrectly that they are only intended for black tanks. Adding to the problem is the likelihood that RV owners are not using enough water in their tanks (either before emptying or a part of a “priming the system” action after they have been emptied and before using them again).
