Anyone have a labeled picture or schematic that shows what each valve on the red and blue water lines does? Seems the owners books lack a great bit of details.
Typically fresh water or low point drains. Picture?

Looking straight down from under the bed there is a blue line that runs forward and aft, inboard of the Furnace , has a valve, closed from factory. No clue where it goes.
So, I got the water heater, pretty simple, so I guess it it the fresh tank dump valve, which is different than the low point in the service bay? Again, thanks forum peeps.:-)
