In my 17 years with this trailer I have never even considered adding water. My bathroom sink does empty into black however. I do use an internal on board sprinkler type sprayer when I dump where available. Maybe that helps?


I am now 9 years+ full time and I NEVER add water after a dump. I do boondock a couple of weeks a year and really want full black tank capacity when I start. If you are going to be using it why start out with extra water in the tank?

You might also check to make sure she isn’t leaving the black tank valve open all the time. That will cause problems for sure.

Bingo! When hooked up at a park, leave your tank valve closed and don't open it till you dump it prior to leaving. Leaving the valve open allows liquids to flow through and the solids to sit. You need all the liquids in it to move the solids.

Couple of full bowls, and generous water when flushing, never any additives. We are full-time though, so it is always being used.

black tank flush after dumping & closing the black valve 3-4 minutes, yes minutes. I drive to the next RV Park and dump as needed. When leaving, dump flush and add as stated. Repeat, not a chance it will clog and the clean water driving helps breakup & clean for the next stop. I have a 57 gallon black and it takes weeks to fill with the added water.

(1 minute = 3-5 gallons depending on flow rate)

I just hold the toilet plunge open for a minute or so. No problems.

Like you, I put about 4 gallons of fresh water in the black tank after emptying - but I've never used any additives. I've also not had any issues in over four years of full-timing. Several times a year I will use the "Geo method" to clean the tanks: about 1/3 tank of clean water with some dish detergent and borax crystals before hitting the road. The agitation and solution help clean off the level sensors and get residual "stuff" off the sides of the tank(s).

I adopted the Geo Method a number of years ago. After I dump the Black tank, I like to put in a 1/2 bottle of Calgon and a good bit of dish soap. I top it off with 3-4 gallons of water. The ride to my home cleanses the tank. I do he same with my Grey Tank. BTW: It never hurts to put some in your sink traps. No odors...

Correct answer (and a couple others). Use granular laundry soap once in while too, before traveling (said prior). That stuuf they sell to breakdown solid waste is useless....It's just deoderizer.

We don’t pre-add water. We go to the bathroom a lot though so it never really dries out.
