Blackwater disposal problem
I have a travel trailer and bought the external large capacity portable tank. Problem is I went to drain the black water and was unable to tell how full the tank was. Ended up filling it all the way...

Get 4 friends to pick up the tote higher than the black tank. Let waste flow back into tank. Shut valve. Lower tote to drain hose.
x2. Nothing has to leave the closed system this way. If you can’t find enough people, lift it up one end at a time onto whatever you can find like chairs, a tailgate, etc. Stand it on one end to gain more height.
Or drill a SMALL hole in the top and blow compressed air into the tote and see if anything moves back into the tank. Plug with a screw.
