When to Dump??

I'm going this weekend for a short trip and will dump the GREY but not the BLACK. Figure the drive home will really liquefy the solids and then next weekend is a 4 day trip which will be our final one for the year, at which time I'll dump and REALLY flush the black tank. Generally if my black tank is 1/3 or less at the end of a weekend I DON"T dump it, it won't hurt anything setting in the tank and like I said driving with it in the tank will help liquefy the solids.

Seriously, as stated, add some fresh water, then dump away.

I was going to say after my first cup of coffee and a cigarette.

Hi,

I tend to dump once every two weeks. I add water to the black tank and use the built in rinser.

In the situation that you are describing, I would add enough fresh water to bring the black tank to about two-thirds full and dump prior to putting the RV into storage. I would also add about 4 or 5 gallons of fresh water to the black tank .

Hey Fellow Ag here. Class of '75. No storage -- I live in Houston. But general consensus seems to be just add water-- LOTS of water-- and dump.

with a black tank flush mounted in the side of the black tank opposite the drain, you can dump at your leisure and not have to fill up the black tank. I used to stop at a full hookup site every third night and dump my tanks, etc.

Yep, it's the water.

We seldom dump when full. If we are ready to move on, we will dump. It's the water to solid ratio that is important to me.
