It's my understanding that the gray tank valve should also remain closed to prevent sewer gas from escaping through the grey tank and out of the roof vent. I was told that this is a source of bad campground odor. In addition, aren't there things like grease and other solids that can build up in the gray tank if it isn't allowed to fill? Another reason to let the gray tank fill is that it provides a nice way to rinse the waste line after dumping and cleaning the black tank.

See, I am learning!

He stated that he was in a permanent site. We also have our motor home parked for months at a time (we use our truck camper for trips).

I see your point about grease and scraps being a problem in the gray tank. It's a housekeeping issue. All of my dishwater is strained before it goes down the drain. I always use a dishpan so I can pour it down the black tank or toss outside, just for this reason.

I have two strainers that nest... one coarse, one very very fine. (Fine enough to catch chopped/pureed blueberry seeds that have gone through my food processor/blender.)

From time to time, I'll close the gray valve and let it fill up as I do a load or two of laundry and then drain it (always pull it before shower time the next morning).

I have never heard about leaving the gray valve closed so that venting odors don't become a problem in between dumps. That's a new one.

Wait until someone asks him what kind of TP he's been using.... things will really get moving then.(and just to add more... I don't put tp down the black tank. It goes into a bag inside an air tight container...and gets tossed outside with the garbage. :B
