Water Heater Winterization
New FR3 owner, trying to nail down the winterization process specifically for the water heater part of it. I live in Georgia and I'm going to blow the lines clear of water with air compressor. I think I understand that part fairly well.
With regards to draining the water heater. I have some questions on how to set the valves in the lines.
My understanding is that the red and blue lines should be open, meaning the valves run parallel with the lines, and the bypass would be closed and perpendicular to the line. To drain and winterize, you turn them opposite their active positions.
That brings me to my question...
Oddly, my hot water (red line) valve only delivers hot water when it's in the OFF position (running perpendicular to the line).
I'm totally lost on what to do with the bypass and how to turn off my hot/cold lines. I have an educated guess what to do, but would like to see SIMPLY just a diagram.
Can anyone post some pics or point me to a diagram of the on positions for the water line valves?
