How often to Empty tanks

Wondering how often most of you empty your black and gray tanks? The wife wants them emptied every time, before we get home. However, I say, if it's only a third full (especially the black), then I don't need or want to dump. I say it can stay in the tank until the next trip.

What's say ya'll?

We always empty the black/grey tanks before we get home. We'd rather start our next trip with empty tanks. On the road we empty when it shows 2/3 on the gauge.

Conventional wisdom is to empty every time. The tanks on RVs are holding tanks, not septic tanks. There is nothing good going on down there over time. At least for the black tank, it should be emptied and flushed every time. Gray should be dumped after black to clean the hose.

Every time we get back. Why would you want that crap (no pun intended) festering in there?! *head scratch*

Sure it can stay in the tank, but the black tank will build up "pyramids" right below the bowl and if not flushed and emptied can (and do) get solidified. Then it's harder and harder to get it cleaned. Lots of water is needed to flush out all the debris. So if your tank is 1/3 full, what's the harm in filling it up and dumping it out? Like Evereddie mentions, they are'nt septic tanks and the little bits of enzyme chemicals you may add don't really do much to digest the goop.

In addition, even the gray tank with soap scum and food particles will splash and adhere to the walls above the water line and very well may dry there and not be redissolved.

Sorry, I'm in agreement with your wife on this one.

If you are under, fill the black and gray tanks with water to reach the 2/3 level and dump away. Nothing good will come from leaving the ugly stuff in your tanks.


After, do your normal rinsing and leave some water in the tanks

My wife and l unless it's a emergency will not put any solids or paper in the black tank. Only liquids only. Mostly liquids only find there way into the black tank at night.
The black tank is always dumped 1st then the gray tank gets dumped. The gray water acts as a rinse. It is best to have more liquids in the tanks, rather than less because the more intense evacuation you can get when dumping the tanks the better job it will do to keep your black/gray tanks cleaner. But l would never leave my tanks with stuff in them just because there is only a small amount in them. Anyway most chemicals for the black tank are only good for a week or 2, after that let the Science experiments begin😳..

I dump all tanks, If hooked to a sewer I will run the black flush for 20 mins or so. The gray tank will start to smell in heat after a week or so, so I also dump that. If I'm traveling that's different I won't dump for 3 days or so.

As most here have said...we all side with your wife.....key point to take from this thread is that there is no sense hauling it home, but if it's only 1/3 full when leaving, just fill it with more water....and like gljurczyk said...if your are travelling then you could wait till the next stop...the swooshing action may actually be beneficial.
