Can’t expel my dark/brown water tank.

Not sure why I can’t expel my waste tank. I’m currently on the hard, have checked my valves to ensure they’re opened. Has anyone had issues with this? Could it be blockage at the throughhull? Could I use a coat hanger to unblock (of course being careful not to puncture the line. Any suggestions appreciated.

Are you dumping it into a garbage can or something? If you are talking about a thru hull, I assume the system is designed to allow overboard discharge? Is there any other “equipment” in line ( as Don asked).

If it was me, I would try the coat hanger thru the thru hull, or a drain snake may work better.
