Interesting... looking at the Scamp
manual (on line) it doesn't really talk about blowing stuff out. What it DOES do is talk about gravity-draining the water, closing up drain valves, pouring in anti-freeze (into the back fill hole??), and using the on-board pressurizer to pump goop thru the system until all the faucets run pink. Does that sound like enough? DO I have to use a pressure hose to blow stuff out?
