RV antifreeze is cheap, but I've always wondered if you diluted the antifreeze with 25% or 30% water, at what temp would it begin to freeze, and fail to protect RV plumbing? Walmart's SuperTech RV ...

So, after all this - is there something I can use in the grey/black tanks that will take some amount of water/dilution and not freeze? I'm thinking, leving northern NY in 0-20 deg. weather and heading south. Just beable to use the bathroom for washing, etc. till we get a day to the south.
BTW - I winterize by draining everything and adding pink stuff to the system.
I've figured that a small amount in the black & gray tanks will not hurt the tank if it freezes.
We have left Michigan in January & February, headed to Florida, used highway rest stops mostly the first day and night. Then after that not worried about the tanks.

Yup, my plan, was just looking to not needing to use rest stop facilities in the current state of things. We will manage.
Water will freeze. When it does it expands. Less than full in a fresh/grey/black tank can freeze but it has room to expand. BUT!!!!! It will freeze first closest to the dump valves and then you cannot open and dump. Fresh tank drain tubing/valves will freeze and crack. When the freeze water cannot expand it cracks piping and valves and especially elbows/T's of fresh pressure lines. Use a 1/2 gallon in each dump tank until you get to warm weather. Doug
