Looking for sewer valve

[ROY UNDERWOOD]

I have a 2019 Alpine 3650RL. When I pull the valve to empty the black water tank it does not drain. I am looking for the location of the valve off the tank to be sure cable is still attached. Currently I have full underbody foam sprayed under RV so I don't want to dig out to much of it looking for the drain valve. Unable to find drawing of valve location.

Black tank is most often directly underneath the toilet. Look for the 3” pipe and then just take out enough screws on the edge to see.

Never seen or heard of any rv having "the full underbody foam sprayed", must be something you or the previous owner did. This could create an entirely different repair process.

Not sure about the full foam, I can see the insulation benefits and sealing holes to restrict critters but man if you ever have a pipe leak or wire loose....anyways I would just get a thin wire and probe back from the outlet, like mentioned before most of the time the tank is directly below the toilet, valve to the back.

Welcome from northern MN. Let us know if you find the valve.

Probably found what he was looking for. A Q&A user. Hopefully he'll return and let us know if he was successful.
