I have not yet used the water system from my 2008 "new to me" 1207, but would like to understand it all prior to actually needing it.
Please let me know if my assumptions are correct. First photo:
Valve A: from fresh water tank. Valve appears closed.
Valve B: Antifreeze siphon valve? Valve appears closed.
Valve C: Hot water low point drain? Probably open?
Valve D: Cold water low point drain? Open?
Second photo, Hot water heater:
Valve A: Cold water supply in. Valve closed.
Valve B: Hot water out. Valve open.
Valve C: Hot water heater bypass. Valve closed.
Please let me know if my assumptions for these valves, and their open/closed positions is correct or not. Thanks!
