RP177 antifreeze intake hose

There's a shutoff on the main water supply side and an auxiliary hose connected on the other side of the pump that you dip into the antifreeze bottle. This is  found under the kitchen sink lower panel. There are great directions all prepared in this forum. Search or wait a few minutes and someone will give you the link.

Thanks for the help, ours is a 2012 and your answer is exactly the situation for the quick disconnect. The vendor we bought it from forgot to leave the antifreeze line in the rig, so I'll get one.

Instead of using antifreeze and giving your water tank a nasty aftertaste will will be a bit problematic to remove you may want to use an air compressor to blow out your lines instead.  We have done this the past 2 winters with no problems and it only takes a couple of minutes to do the whole thing.  I will use about 24 oz. of antifreeze for the 3 traps in our 177 however.

Mark, thanks for the update.  I wasn't aware of this option, must be on the 2012 models or newer as we don't have this on our 2011 unit.

JGF, we have a 2012 177, ours has a 3way valve with hose (my rv place had it hooked up when we bought the pod) and as has been stated just turn the valve inline so the pump sucks from the antifreeze and Bob's your uncle.... No antifreeze gets into your fresh water tank this way. I do both when winterizing, I blow out my lines, with taps open, then using pump pull RV antifreeze until I see pink coming out of all taps (turning one tap on at a time.) Maybe overkill but only takes 30 minutes tops, likely less never timed it.. Every spring sanatize your fresh water tank as the manual says and you have no problem with your fresh water.
