I am winterizing for the first time. I have drained everything and am ready to start sucking the pink stuff. When I pulled the panel and found two valves (see the pic below). It looks like one is to prevent the hot water heater from getting anti-freeze in it and the other is to prevent water from entering the hot water pipes after the hot water heater.
Do I need to turn off both to not fill the HWater heater with the pink stuff?
My guess to just turn off the one controlling the water to the heater so the hot water pipes get the pink stuff too. This of course assumes there is some sort of backflow valve on the hot water outlet from the heater.
thanks,
Mark

Mike,
I was just doing a search on RV.net to remind myself how to de-winterize and came across a post you made referencing your reply to me in this post. It reminded me that I never followed up on this post with a thank you so... Thanks!
Mark

Mark,
In your photo above, the bottom valve(cold water inlet) is OPEN. The other valve(in the Blue by-pass line to the left) is CLOSED.
To winterize, CLOSE the bottom valve and OPEN the by-pass valve.
NOTE: The HOT water outlet(at the top) has a built-in (one-way)check valve to prevent Anti-Freeze from intering the water heater tank.
Don't forget to drain the water heater by removing the Anode Rod.
