I've read everything anyone's posted on where this is supposed to be, but can't find it anywhere. Reading left to right, the grey tank #1 is empty and #2 is 2/3 full. I can see the entire run of black PVC from where it exits the belly cover to the main sewer line and there's no valve. There's no handle anywhere else I can see either, including under the sink or behind the inside access panel to the back of the water heater & vac. Any suggestions?
