Yep. It works great with compressed air hooked to the city water connection to blow out the lines for winterization. I use a water regulator with an air chuck threaded on it to keep from over pressurizing the system with air. Alot of people don't know that it works for air the same it does for water...
I'm thinking about hooking up a short hose to the hot side drain for outdoor hot water access. I like to cook over the fire and don't like to take the nasty cast iron into the sink inside.
