Unknown Hose

[SwensonBarrettBunch]

I have a new Sierra 302BHD. Under the trailer I can see the fresh water tank drain, but right beside it is another hose that does not have a plug in it. The problem is when I back the trailer up hill water comes out of this hose. Does anyone know what the hose is for? I really don't want to take the panels off the belly to find out. Thanks

Overflow/water tank vent?

[SwensonBarrettBunch]

That is what I thought. I know the tank is vented through a small hole next to the fill port. I will probably plug this line because we do alot of dry camping and need as much water in the tank as possible not leaking out of this hose. Thanks again.

Probably an overflow. Try filling up a sink or tub until it gets to the overflow hole. See if water comes out from that hose.

Is it possible that it's the tank vent hose, and disconnected from the screened vent in the fill port area? Before plugging it I'd add some water to the fresh tank and feel for air out of the vent screen and also that hose just to be sure. If it is the fresh tank vent, plugging it will cause refilling problems.

It will be the tank vent hose...........our Wildcat is the same way.

The screen hole above the fill is actually caulked shut on ours, since there is nothing connected to it from behind.

My salem has an overflow in the same place and vent on the fill port is caulked shut.

If you are losing too much water out of the overflow while traveling, you can install a shut off valve so as to close the hose while traveling, but will need to open it when filling to let air out of the tank.
