Clogged Black Tank

I think my black tank is clogged....pretty gross! Only a small tickle is coming out when the valve is open....Wondering if anyone has any tips on how to unclog this ??? Not looking forward to fixing this issue!

  • Did you verify that the tank valve is actually opening and not just opening a crack?
  • If you are in a class A the first thing I would do is take a drive. It may slosh around and break things loose.
  • try dumping WARM to HOT water directly into the toilet.... depending on how your plumbing runs, you MAY be able to use the "wand" but some drains make a quick bend and are not accessible with those..
