Yep yep pep. Plumbing antifreeze or RV. Same stuff. Pink in color. Totally non toxic. When I winterize my fifth it goes into all the traps, the toilet and ALL the water lines. Been doing it since 1993, and we're not dead yet. No harm will come to the well or septic system. PS we do use water to flush the lines in the spring and run it for about 2 minutes. Don't ever worry about the stuff in the traps. Rick

 

Yea, but you put that extra letter in a lot of your words, eh??????

MnTom, I'm disappointed in you. In my post I even spelled colour as color so you Americans would recognize it.
