De-winterizing checklist

Thank you. Having heard the PINK anti-freeze that should be used was not toxic, but never hurts to check and check again

According to my sources, if the antifreeze is propylene glycol (not the ethylene glycol that is used in automotives), it is much less likely to be attractive and toxic to animals.   I would not test this theory by feeding it to anyone but it should be less toxic.    Personally, I would not let the animals drink the water that I would drain out but once the area is dry, it should be acceptable to allow access to it. 

Shouldn't hurt your grass, if that is what you are asking.

Should be ok, it is a food-grade chemical which won't hurt wildlife if they drink it.

Originally posted by mountain mist   I had been wondering just how to de-winterize, this being my first time. First, have I heard correctly that the anti-freeze is ok to put in a dump station?   Yes, it's OK.   Now, when you have flushed the lines, which holding tank does this go into?   The toilet will go into the black tank, all else will go into the grey water tank.   Asking since adding the chemicals to the black tank will have you just dumping them when you go to the dump station.   Personally, I think you would probably be OK without them - if only camping a day or two.  But, the chemical would help control odor and break down the waste.  I'd splurge and add chemical.
