Your friend obviously had the black tank COMPLETELY full when his poor wife stepped in the pedal.
First thing to remember/realize is NEVER rely on the sensors, they are notorious for being so inaccurate that they are typically useless. You can spend time, $$ on miracle products & lots of effort trying to keep them working then the tank fills again & they'll quit.
Your toilet will have a distinctive "burp/gurgle" when you flush it that will be an indication it's "time".
The bath grey tank will back up into the shower when full, usually in the middle of the wife's shower.
The kitchen tank, if separate, should be good til you dump the others & often smells as bad or worse than the black.
