I take it CG Septic truck hooks up to drain line.opens dump valve and then SUCKS tank contents out.
2 issues....
Drain valve not opening. Otherwise vacuum from truck would suck it dry
High vacuum being used can damage tank....sucks contents out faster then vent line can allow air back in (waste tanks do NOT hold up very well under a vacuum)
Did 'honey wagon get anything out of grey tank?
Grey YES.Black NO---black tank drain valve NOT opening
Will need to open up underbelly and visual inspect drain valve....open it using pliers etc.
