Water heater question
Hey everyone, im trying to de winterize a camper I just bought (first timer) and want to make sure I have the valves right before kicking on the water heater. The valve on the vertical was closed when I opened the panel. Previous owner didn't use antifreeze - just blew out the lines somehow with air.
Does this look right? See attached photo. Cold water (because I haven't kicked the heater on) comes out the hot faucet.
Thanks for any advice! Just don't want to mess anything up by running the water heater if it's dry in there.
