Don't have pictures, but it's pretty easy once you get used to clawing your way around the guts of your coach!
The quarter-turn valves are nice. In-line with the piping is open. 90 degrees to the piping is closed. Now, as for where the right valves are, that's another story!
In our 2014 24.1
There are three on the back of the water-heater. Access is had by removing the louvered panel under the closet. Replace the 2-inch screws holding the louver with 3/4" while you're in there to keep your water pipes and heater tubes puncture-free.
To winterize: close the inlet and outlet valves (top and bottom of the WH) and open the bypass valve. It's the one that connects the inlet and outlet pipes. Reverse for use.
Under the curb-side bed near the water tank - there are two more. One that connects the anti-freeze inlet tube. Open to suck anti-freeze into the pump. Closed for normal use.
And a fourth that was really hard to see in ours, cause it was hidden under heater tubes. It's on the tank outlet tube. Close it to winterize or the antifreeze draw tube won't... Open for normal use.
Have fun.
