Black Tank valve

[wjohnson101a]

I have a 2018 Eagle 336FBOK, this model has two black tanks, I am able to drain one of them but the one for the half bath toilet is full and will not drain, is there a separate valve for this tank? If so where is it located. Thanks

I’m not familiar with your unit but -

1 - check your manual, or
2 - Jayco labels the valve locations along the outside of their units: check for these, or
3 - If you still cannot locate the label look under the unit for the valve location.

Sorry, but that’s the best I can do for you.

There has to be a second valve, probably underneath somewhere. Have to get underneath and take a look. If slides are out, that makes it a little more difficult to get under the correct location. But it has to be there.

Yes, there is another valve pull under the belly below the control center where the other valves are located. The one under the belly is for the 1/2 bath. There is also a tank flush on the side of the RV above and to the rear of the control center for the 1/2 bath black tank.
