loose part found down by freshwater drain - anyone recognize it???

[SNY SD UP]

It is a brass angle stop knob.  Because it is brass, I believe it may have something to do with a "Gas valve".  It was on the (curb-side/under bed) floor next to the fresh water drain valve.

I looked/felt around the WH and the HTR but did not see where it might go.

Has anyone seen this before and do you know where it should be located?

Thank You,  B Out

It’s the lever from your hot water heater bypass valve. Normally located on the back side of the hot water heater.

Torque the set screw as tightly as you can.  Mine was not properly torqued at the factory, and so came off during our 2000+ mile drive home to Idaho a couple of weeks ago.
