Well, they use propylene glycol in ice cream, so best worry about your heart valves.
When eating ice cream, which I do a lot, the last thing I think about is the ingredients. I'd rather focus on the toppings!

Reading previous threads on this forum, I thought that using RV antifreeze left an unpleasant taste in the pipes for months afterwards, which put me down the path of considering the compressed air method. I've subsequently learned that there are many types of RV antifreeze though, and I'm not sure if propylene glycol based antifreezes leave as much aftertaste. Perhaps this would be a good point for me to re-examine those earlier assumptions.
The Viair works because it has adequate pressure and he did one line at a time (indicative of low cfm). Trailer winterizing methods with compressed air generally recommend 30-40 psi. You might not need that much but I am sure you need more than 0.25.
Don't use the compressed air from a gas station. It has too much pressure! The high pressure can blow a a pipe or seal. When using compressed air, it should be set to 30lbs.

I started out using an air compressor and eventually changed over to using antifreeze. I never felt 100% sure that all the water was out of the system - especially the toilet. With the antifreeze (& 3 way valve) I can see the pink flowing out and know that I have protection. The cost of having the toilet valve crack just isn't worth the chance to me. I can have the system winterized in less than five minutes and won't hesitate to use the trailer due to having to rewinterize.

In my 19 I was fortunate to have the low-point drain, which did a great job just using gravity.
Both methods take about the same time to do, with the exception of not having to go pick up antifreeze if using air. Both methods work just as effectively.![]()
Jim, aren't you still putting some antifreeze down the drains to protect the traps and some in the black tank? I would think you still need at least a gallon.
Okay, you caught me there. I do put some into the P-traps, usually just a cup or so.Nothing in the black tank though, as I drain it off before winter.
I have a few jugs of antifreeze my mom gave me years ago that I still have not used up.
...One ice cream cone will supply you with more propylene glycol than you could get from hundreds of years in a well maintained RV water system.
One colonoscopy...
"Four liters of polyethylene glycol 3350 with balanced electrolytes for colonoscopy preparation..."
That's about 100 lifetimes in my opinion. (So looking forward to mine next month.)

If you forgo the drip, you are allowed to drive home after. Just a minor discomfort is all.LOL - I was going to make that same point Alan, but figured someone would point out that polyethylene glycol and propylene gylcol are the precisely the same chemical. Good luck - the only good thing about it is the afterglow after the conscious sedation. ;D
