Tank vent

[KWDAILYD]

I have a 2012 Eagle 321rlts. Our first trip out this season and the toilet is burping. Log would tell me the vent is clogged. Went on the roof and there are two vents. Ran water down each vent. One seems to be for one grey tank ant the other for the second grey tank. I started by emptying all tanks. I can run water down each vent and only get water out of the grey tanks. Nothing goes into the black tank. I am baffled how the black tank vents.

The vent pipe might have slid down and is sitting on/near the bottom of the black tank. Happened to us. With the cap off try lifting the pipe up and see if that helps.

Had both vent caps off yesterday. Ran water down both. One seems to go to one grey tank, the other vent seems to go to the other grey tank. Both vents take water without it backing up onto the vent pipe. I would think if one didn't down water would back up in the pipe.
