Winterizing water system?
Anyone put RV antifreeze into fresh water tank to pump and circulate into lines. Do not have bypass hose from pump to connect to antifreeze bottle.

No need to worry about your water tank catching fire or dying if you ingest trace amounts (we are talking RV antifreeze not automotive engine antifreeze which is a whole different ball game).
The main reason you don't want to simply put it in your tank is you need far more antifreeze to do your system and you need to flush the tank multiple times to get the taste out.
The issue is most tank pickups are an inch or so above the bottom, so in order to get enough in the tank that the pump will pick it up, requires a few gallons. Then it leaves a layer an inch or two deep on the bottom of the tank. The first tank you use in the spring will have 2-3 gal of antifreeze mixed in. Then when you drain and refill, it probably still has 1/2 gal mixed in the water at the bottom. It takes 3-4 fills before you get it thinned out enough that the taste isn't objectionable. It won't hurt you but it makes it unpleasant to drink.
