No one reads instructions….. and everyone has a better way of doing it anyway.I have always read all the different ways people winterize and wondered why they don’t put directions in the manual on how to do it right.
My RV owners manuals have detailed instructions on how to winterize and mostly all RVs are plumbed the same for winterizing. Hot water heater bypass and freshwater tank bypass is accomplished with a turn of a knob too keep pink out of those tanks, it has no business being in there. The instructions also tell you to leave the drain plug out of the hot water heater so it can breathe. Mine even came with a replacement plug with a screen to keep bugs out while in storage. RVs all have “winterizing ports” to hook your pink bottle directly to. Couldn’t be easier. Also tells you how to sanitize the system when returning to service by adding 1/4 cup of household disinfecting bleach in a 1 gallon jug of water for each 15 gallon increment of freshwater tank capacity, pour it in the tank, fill the tank with water, return the bypass knobs to normal so that the bleach solution goes in the hot water heater, run all of the fixtures. Leave it set at least 4 hours, not more than 24 hours and rinse. I’ve never had smells or any other problem. It just takes a lot longer to do the boat than the RV, like an hour and a half vs 15 minutes, because nothing is easy on a boat, sometimes by design.
Just look above …this group can’t even agree on what % vinegar to use ….. and for the record I’ve never used vinegar….. I’m 100% behind Trump ….. bleach the bitch !
