I would not dilute the antifreeze. Keep in mind that unlike automotive antifreeze the plumbing stuff does actually turn solid. It just doesn't expand when frozen. So adding water could give you a pocket that actually expands. Unlike a car antifreeze where you would bring the strength down (up?) to -30 from -50, you could destroy it. Spend $20 on the adapter and do it right.

(Most RV places sell the same thing for around $20.)

And Nufy- I've said it before... a buddy of mine used to do what you do. And for 3 winters in a row he had no issues. Then the 4th winter he found that water had settled in a way that caused him a burst pipe. The worst thing was he found it as he was selling his trailer, and the buyer wanted to see how everything worked.

Spend $20 upfront on the kit and $10 per year after that on antifreeze, and that's it.
