So, it appears that not all non-toxic RV antifreeze products (the so-called "pink stuff") are the same. Some brands are ethanol based (like the WalMart's SuperTech brand) and some are propylene glycol based (not poisonous ethylene glycol). The Escape Owner's Manual says in one place (page 54) to pour RV antifreeze in the drain traps and toilet to winterize, but in another place (page 55), it says don't put alcohol in the toilet or drains. But nowhere in the manual is there a distinction made between ethanol vs propylene glycol based types. So what's up with that? Also, some web sites (so take it for what it's worth) caution that alcohol-based RV antifreeze can damage rubber components in the water systems. Has anyone who has winterized using the "pink stuff" for multiple years encountered problems with deteriorating rubber gaskets, seals, etc.? For the record, we've previously always used the air blow-out method and had good luck except for one year when apparently enough water re-pooled in the shower faucet that it froze and cracked (easy replacement). We're trying the "pink stuff" (ethanol based) for the first time this winter and hope we haven't made a long-term mistake in doing so. Maybe I'll go back now and use the air method to blow out the "pink stuff". Further insight, anyone?
