Quick Winterizing Question

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)?

    In the course of adding pink to the toilet some of it is inevitably going to end up in the black water tank and work it's way down to the waste gate. 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. ;)
  • I dump antifreeze down the sinks and put some in the toilet. I consider it cheap protection at a few $/gallon.
