Using toilet in winter
« on: September 01, 2012, 04:54:32 AM »
First time owner, and would like to know if it's possible to use the toilet in the winter if the blackwater holding tank is fill and flush with antifreeze? I can't see a problem, except the possibilities of diluting the antifreeze with bodily fluids which might raise the freezing point of the antifreeze.

For decades in the past we always used our RV's in all seasons here in Colorado. Our current RV is heated so that we have no problem with holding tanks freezing when managed as designed.

In the previous 5 RV's, over the decades, with non-heated tanks, we just put antifreeze in the drains to each holding tank prior to a winter trip. Years ago we also used salt in the holding tanks, the kind sold for defrosting sidwalks.

With antifreeze in the holding tanks prior to use you shouold have no problem freezing before draining the tanks. We never had any problem doing this system.

We've used ours in the winter while traveling to warmer climes. With no water in the water tank, we would carry gallon bottles of water for flushing, cooking, etc.
