Blue water in black tank - does it freeze?

If I couldn't dump I would just add some antifreeze - just in case.

I know what black water is, I know gray water... I know what is meant by "pink stuff." I have used blue windshield wiper fluid in my black tank and cassette reservoir (but I don't think that is what we are talking 'bout here.)

Is blue water just another term for regular potable water in the domestic pluming?

Blue water probably = tank deodorizer in the water. He’ll be fine...

I’m afraid I’m just as ignorant. It’s been so long since I’d used the blue holding tank chemical that I forgot that the most widely used one is blue :S

Thanks for the tips. It is water with deodorizer I am sure based on the scent in the bathroom. For now, I put some RV anti freeze in it until I get home from an elk trip for a few days. After that, I'll drive it somewhere and drain it properly and winterize with RV antifreeze.

Dump the tanks, winterize the water system with pink RV antifreeze and don’t forget to winterize/flush the toilet.

Blue water. The stuff the chit sucker puts back in the tank in the blue room after he removes the baby Ruth’s and corn!

Blue water makes me think its got whatever the base water quantity plus the standard Tank stink solution (which is generally blue) in it. If the tank is predominately, empty, it won't cause damage, but it will freeze.

Years ago when I bought a 33ft travel trailer from Nelson's RV,there was work that had to be done with it before I took ownership and we lived 100 miles away in McCall Idaho..So they let us stay in it on the lot while they took acre of mostly outside minor problems...

The guy took a 3# coffee can full of rock salt and poured it down the toilet..The black never froze there in the lot or the long trip back home in freezing temps..

Simple and cheap as well as RV anti-freeze..If in doubt,put something in it and be safe..They will crack and break..

Unless the tank is right full where the water has nowhere to go when it expands it won't cause a problem when it freezes.

The freezing temperature of blue water is lower than regular water but nowhere near as low as the pink stuff.

You may find your dump valves frozen solid and will not move till thawed if water is in your waste tanks. This is not a problem if you plan to wait till Spring to use the camper again or you have access to the valves with a hair drier.
