When you see water standing below toilet valve, it is time to dump black tank. No sensors needed just eyes.
Exactly.... Who cares if the sensor works or not.If you can see you know when it needs to be dumped.Our sensor stopped working on second outing and I really dont care.I guess some people get some kind of satisfaction by looking at the red dot next to empty or full even when its prolly wrong.And who care how clean your******tank is inside.Its a holding tank for crap.Just add alot of water and be done with it.No need to obsess over a******tank.
