I've always cleared my water lines in the fall by blowing compressed air through the city water inlet. No problems in eight or nine years.
However, after seeing this diagram:

I realized I was never blowing air through the water pump to clear it because of the one way valve.
After letting the fresh waer tank drain, has anyone turned on the water pump briefly and blown a little air through the system to clear the water pump?
To do that, I'd need to close the main drain, close the fill cap and pump air into the overflow tube.
Make sense? Dumb idea?
Thanks
