Our black tank is FULL & won't drain.

My husband thinks that the rod that goes into the valve has detached from the drain plate. So the rod goes back & forth but the valve doesn't seem to be opening.

Is there another way to get the black tank drain valve to open??

ANY ideas to solve this problem will be much appreciated!

We have a 2009 Mobile Suites 38RSSB3.
