Not Dumping?

Can I just pour anitfreeze into the black tank instead of having to drive the TT across town to a dump site? The tank doesn't even read 1/4 full.

I have been giving a similar problem some thought. Should I keep some antifreeze in the tanks during winter use, and how much? If I were storing it over the winter howerver, I would drain it for sure. If it aint in the tank it cant freeze there, and a freeze could turn into a nasty scenerio.

I drain & rinse my black tank when the fresh water lines are winterized.

For occaisional Airstreaming after that, we use the modern-day equivalent of a chamber pot purchased from Wal-Mart for around $20.

FWIW, although antifreeze can be added to the tank to protect it, I worry more about the dump valve - all that crap suspended in a variety of liquids does not strike me as good for the valve's rubber parts in freezing conditions.

I don't know if that is a good idea, not just because of the freeze. The breakdown of material in a black tank generates ammonia and other things that work in the deterioration the seals in the valves.

Thanks!

Well thanks for the advice all. The weather unexpectedly cleared this afternoon from the freezing fog and snow we had this morning, so I hooked up quick and dumped across town. Now I don't have to worry about it all winter.

Good advice...I never thought of the residual antifreeze in my grey tank after winterizing. I know I can do a rinse to the black tank but what about the grey? I don't think there is any way around rinsing it out now that I have anitfreeze in the traps except to drain what might be in there from the dump valve. I did put window wash in the toilet...I'm wondering if it would be beneficial to pour the rest of the gallon in the back tank to protect and lubricate the seals. What do you think and is it really something to worry about??

Ah, keep in mind that RV antifreeze, if diluted (even with black water), will lose much of its protective capacity. Read the label carefully; you may wind up having to put a LOT of antifreeze in there in order to keep it from freezing.

I drain both tanks before I winterize. Water freezes and you don't want it anywhere in your system. After I winterize, I drain the gray tank one last time to get rid of the last bit of water dislodged from the traps when I pour AF in them.

If you drink enough alcohol, you theoretically won't need antifreeze in your black tank...

Terry,
Are you willing to test that theory?

I would, but I live too far South for any tests to be meaningful. I will have to let someone in a more Northern clime perform the test... If anyone tries this, make sure you use copious amounts of Bacardi 151 rum-- Then even if it doesn't work, you won't care.
