Valves and Hot Water Bypass

[Jody5280]

Hi - need some basic help. We bought a 1999 Bambi last year and had it winterized. I was supposed to pay attention while the guy winterized so I could de-winterize it. I should have taken notes (sigh). Can folks help me understand the valves on the attached photo?

Hopefully the colors come through on the photo....

There are 5 valves in the photo. The ones circled in yellow are drain valves. I sort of understand that the one circled with green is the hot water bypass so if we use antifreeze the hot water heater doesn’t uptake.

Is the one circled with red taking water (in theory once hot) out of the hot water tank? Is the one circled in blue taking water to the hot water tank?

Assume to de-winterize, I flush then shut the drain valves (obvious) and shut the bypass (circled in green) and open the ones circled in red and blue?

Any description or details about the water lines shown is greatly appreciated!

Thanks much! Jody.

You paid better attention than you thought. You are correct in your description of all the valves, and what to do to dewinterize.
