I know...I know... yet another newby winterizing question. I understand about emptying the fresh water, blowing out the lines & pump and adding antifreeze to the sink traps, but what (if anything) do you do to the holding tanks (other than empty them)?

I dump antifreeze down the sinks and put some in the toilet. I consider it cheap protection at a few $/gallon.

Likewise any pink added to the sinks & shower is going to fill the traps, any excess will drain into the grey water tank and work it's way over to that waste gate, a good thing in both cases. Fresh water holding tank - just empty it as best you can and forgetaboutit. ;)

For me....Fill then empty.... Repeat. End up with an empty tank that is as clean as possible.I then add pink stuff to all the traps (knowing, as others have said, that some of the pink stuff will end up in tank). I add a little extra down the toilet into the black water tank. Kinda like you would during normal use with water (maybe blue stuff) but I use anti-freeze (no blue stuff) to keep the bottom of the tank from drying out......just in case there is some "accumalation" in there.

A little water in the bottom of a large tank will not hurt anything. I pump antifreeze thru my lines and some goes down the drains into the emptied tanks. It will be somewhat diluted but will not cause problems in freezing temps due to the small amount.

The winterizing is to prevent water freezing, expanding, and rupturing pipes and fittings. An empty tank won't freeze.

I almost forgot the toilet myself last week.

Thanks gang. This is about what I thought, but since this is our first TT and we bought it used with no instructions, I wanted to double check. You guys are the greatest!
