Where is the black water valve

just purchased a 2005 thor grand junction 31 tgs. The black water valve is leaking and will the handle does not push in all the way. I believe previous owner left tank open all the time when hooked up to a septic system. Nice present he left me. I have now filled and emptied the tank about 10 times and water is running very clear. Ive tried adding a valve at discharge and keeping black open hoping to wet out what may be stuck in valve. No luck.

The trailer has winter package and valves are under insulation package and i do not see any obvious access areas. Wondering how difficult it will be to get to it, and where i should start taking off insulation package. Anyone have pics to show where to look???

The valve is replaceable and should be no more the 3 or 4 feet form the outside. You can cut a large 3 sided square out of the plastic leaving the forward side intact to act as a hinge. Pull it down and you should find the valve. I'm assuming here that yours are cable pulls since you cant see them. It may be just inches away from the pull handles. The valve is held in place with 4 screws. Amazon is your friend. Be very sure the tank is empty first unless you are in possession of a hazmat suit! Put the plastic back in place with Gorrila tape.

If that sound like a lot of work then just leave the one you have open and install a twist on gate valve where you place you sewer hose. Put a screw in it to keep it inplace.

All the sewer parts you will ever need.

He's got you pointed in the right direction.
So I'll just say, "Welcome to the Forum"!
... and post a pic of what to avoid...
