I presume winterizing? It is white, about a foot and a half, has a plug (looks like something you'd stick into somewhere, not threaded) the other end is just cut.

I asked the same question - maybe on this forum. It is for winterizing.
The hose attaches to the suction or intake side of the water pump using the fitting and the other end goes into the jug of RV antifreeze

Yup, that's the pump. Intake is on the right. Disconnect it and hook up the winterizing hose.
I dont't see a valve, usually is none. The line you would disconnect is connected to the FW tank. Any maybe 40 gallons of water or more. Make sure to drain that first!
