Water in fresh water tank this time of year.

Hi,

The more water there is in the tank the less likely it is to freeze. I'd go for 9/10ths full so it can slosh around a bit.

It does depend on where the fresh water tank is. My is under the dinette--so it is in a heated area.

When we leave during the winter for warmer weather, we normally wait and springerize once we get there.

We have also waited until we are in a warmer area before de-winterizing the coach, even though my plumbing bay is heated and the tanks are enclosed. It is just easier to take a few gallon jugs of fresh water to use than take a chance. We can still use the toilet, just not the shower.

The only place I place the pink antifreeze is the drain traps. I drain and blow all the water lines with compressed air. Many of the SP we go to don't have full hook ups, most have water and power. This way I don't have to run gallons of water through the system to flush out the lines.

I also don't worry unless the temp is expected to get below about 28 degrees overnight, the water in the lines and tanks will not freeze that fast.

We flush the toilet with antifreeze. The Black Tank already as a gallon or so of the pink stuff.

Don't forget that many RVs have drain lines extending below the enclosed area.

We generally don't un-winterize ("springerize" - that's a good word!) until we see night temps in the high 30's. We just use bottled water; and antifreeze to flush the toilet in normal cold weather.

I have to admit, that as we came home from FL in late January and the temps were in the single-digits, we adopted a "no liquids down the drain" policy, after I read that urine can freeze around 28 degrees. A bucket, a trash bag, and some kitty litter handled those middle-of-the-night trips...... not elegant, but it works.

A few years ago in Jan. we had to return home from Arizona because of my father-in-law's health. It was 9 degrees there and we did not winterize the trailer. Kept the furnace on and everything was fine. Only problem was dumping. There was a little water behind the sewer cap and it froze. Had to run water on the cap to thaw it. It made a ice covered spot on the ground but nothing else was frozen.

I wouldn't do it where I live, temp this AM -6F. If you are sure the temps will stay above freezing - no problem. Depends a lot on how your RV is plumbed.
