Black & Grey water sensor accuracy
Just got back from the shakedown trip and came across a little issue I wasn't expecting. Cleaning dishes in the sink and it wasn't draining, thought to check the panel above the fridge with all the sensor buttons (Black/Grey/Fresh/etc) and while the black was still on empty the grey showed 2/3. So I went out and pulled the grey open to drain which quickly emptied the sink.
My question to everyone here is this, when your grey tank fills up is the kitchen sink your first place yours backs up? In my parents trailer their shower is where it backs up first as its the lowest point, I can't think of any logical reason the kitchen sink would have backed up and not the shower first as it's also the lowest point in the RV.
Secondly, do you find that while your sensor may be showing 2/3 that it's possibly full? I was expecting to see that sensor be at "Full" when the sink backed up, but it wasn't.
Starting to wonder if I have a clog somewhere...
