RV Antifreeze
I just came from an RV repair place and the owner warned me not to use RV antifreeze containing alcohol because it deteriorates the rubber seals. He then went into a sales pitch for his own rv antifr...

1. RV antifreeze is REQUIRED if you have a AquaHot type system. Blowing out is not enough per Aqua Hot.
2. RV antifreeze is NOT a good idea for Icemaker molds. Kind of leaves a slime and takes a good flush and cleaning out to remove it.
3. RV antifreeze is REQUIRED to be installed in P traps. You have to have something in there to prevent freezing
4. propylene based or regular RV antifreeze--- makes no difference.
5. Gravity draining is NOT a good way to drain. I like it tho. It makes me good money in the spring when the people that gravity drain have those frozen broken parts.
6. Gravity draining will NOT get rid of the water in the Black Tank Flush Check valve
7. Gravity draining will NOT get rid of the water in the Water solenoids of Icemakers(RV or Residential) and Water thru the door solenoids.
8. Gravity draining will not get rid of the water in various types of onboard water filters and their housings.
9. AS others have noted, Gravity does not get rid of water in a standard RV toilet water valve
10. Gravity draining will NOT get rid of water in the solenoid of a Macerator toilet or its Macerator Pump
11. Gravity draining will not get rid of the water in an external Macerator drain pump.
LAST, do what you want. If you do not do it correctly, you either pay for new parts or pay ME to replace the parts with Labor and cost of parts. Doug
Well, I will continue to gravity drain, as except for the toilet (which I learned the hard way), I had no issues gravity draining. Probably because except for the toilet I have none of the things you say gravity draining won't get rid of water. :D (and the main water filter, but you have to remove that even if doing an anti-freeze flush, so it doesn't really count)
Suppose it wouldn't be hard to do a compressed air flush though, especially as I already own a compressor so I'd just need some adapters. That would ensure everything was good, and if I remember the toilet manual correctly you can do a compressed air flush and not have to disconnect the line or run antifreeze. I'll double check that before winter gets here. I'm certainly not going to do an anti-freeze flush as we plan on camping at least once a month through the winter, with water. Not going to put anti-freeze in the water system and flush it out every month for 5 months!
