Newbie trying to winterize

[Wbreagy]

Have a 2011 Georgetown 320 DS. Finally found the drain for the hot water heater, but not sure I found the bypass . In the cabinet under the kitchen sink there is a panel marked "not for storage". After removing this panel I found the water pump and some water lines. There are three valves on the various lines. Are these the HW bypass valves? If so, do I turn all three 90 degrees to bypass the HW heater? For some reason, I thought there were only two bypass valves.

Not for sure...you need to find the valves that are directly behind the water heater.

3 valves are normal.
You should have one on a line going to the bottom of your water heater tank. This will be the cold water inlet.
Then there will be one on a line coming out towards the top of your water heater tank. This is the hot water outlet.
Then one valve on a line connecting the two lines. This is your bypass valve.
The valves are in the closed position when perpendicular to the water line and open when parallel.
To winterize, drain the hot water tank, close the cold inlet and hot outlet valves and open the bypass valve.

I hope this helps.

Thank you, Grhodes50. You described my configuration perfectly. I guess I'm in business. I've never seen an industry that gets away with so little documentation for such a complex product as a motorhome.

Most manuals are generic and offer very little detailed instructions.
That's why a thorough PDI is important, but i think I knew as much about the tt as the service tech on the last one I had. Most of my questions were answered with "I don't know" or "I'm not sure."
I eventually figured everything out and I'm quite comfortable with the tt now.
