2020 21FBRS: Valve under Bathroom Sink

[rrosson67]

Went to de-winterize our 2020 21FBRS and when reviewing the steps in the forest river manual I see no step that includes the valve underneath the bathroom sink. In opening the access panel on the left side of the bed I was able to locate the two valves for bypass of the water heater. Underneath the bathroom sink there is no storage due to this is home to the water pump, all the water connections and this one valve. For reference this valve sits just left of the pump.

Getting the itch to be ready to get away once the all clear is given so any help would be appreciated.

TIA

A valve to ingest antifreeze using the pump during winterization possibly?

A photo would have helped.

I don't have your model but here is how mine works...

The lever on the valve is inline with the hose that goes to the antifreeze suction line/port for winterization... and inline with the fresh tank suction hose during normal use.

Sorry ditto 5picker

Now the position it is in for normal use for filling for winter?

I have 2019 21FBRS and all of this stuff is in the basement storage behind the hot water heater on mine.

We can't see where the hoses go that are attached to the valve but I'd be 99.9% sure it is in the normal position. If the hose that goes vertically heads towards the sidewall and the outside connection for the antifreeze port, then it is in the normal position to draw water from the fresh tank as shown in your photo.

To winterize, you move the lever so it is inline with that vertical hose, to suck antifreeze from the outside port.

As I said in my earlier post, the valve lever is parallel with the hose it is drawing from.

This is correct. I have this trailer, and that valve goes straight to the sidewall and the winterizing outlet on the outside.
