What’s the orange knob? Obviously the red and blue are hot and cold water for the washing machine. The orange knob is extremely hard to turn and I don’t want to force it without knowing what it is. Any ideas?

Is there now, or was there previously a gas dryer? May be a natural gas valve.
Seems like a good guess.
Not that I know of. None of our other appliances are gas, everything is electric.
Outdoor spiggot on that wall? Might be a cutoff if you’re in a cold climate
Pacific Northwest, so not too cold. I was hoping it was a whole house shut off but I don’t want to break it either.
I’ve seen them on the “security group” for boilers in Europe as a pressure release valve. There’s a thick spring inside which is what makes it hard to turn. The instructions say to open that valve once a month and verify that water discharges. If no water discharges, then it means the pressure relief will not function when something else goes wrong and the pressure gets out of control.
I’ve not seen orange nobs anywhere else, but different regions may differ. Orange is just one color by one maker. I’ve noticed sometimes they are green, red, or yellow.
