Winterizing water system?

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.

So while it's basically safe normanly the pickup tube in your freshwater tank cannot get the last few gallons out of the tank. It would require several gallons just to get the antifreeze into your water lines

Why not add a winterizing kit that lets you pump straight from the jug.
Inexpensive, easy and permanent.

Winterizing Kit....here.

Isn't it same concept? Will look at getting kit seems like easy install. Thanks

Not really the pink stuff is both flammable and not to be ingested - so you have a major problem getting it all out of the tank
