I'm a firm believer in a tank wand. Before I knew you could buy one I made my own.

Actually, if you get a wet butt, it's really full...lol

Toilet 'Burps'....time to dump
Sink/shower draining slower....time to dump
Pump goes 'Burrrrrrrp'...should have added more water earlier

Best way and most foolproof way to check your BW level is look... right down the tirlet. OEM level gauges are useless. If the black gets too full, your tirlet won't flush and if the grey is too full, you shower won't drain.

The only indicator that works reliably is for fresh water.

Stuff stuck to the sensors in the black tank. In our last trailer I could dump, run the tank flush and the sensor read F and E, how could that be? Guess only the top of the tank was full and the bottom 2/3 was empty.
