Resolved Black tank yellow light coming on way too early

[Rich W.]

I just use lots of water. Just got back from a month with perfect black tank system performance on “wet bowl”. Put it on dry bowl for the ride home, and once again, the amber light was still on after dumping tanks. One flushing with a full tank of mostly water and it will be back to normal. Doesn't really matter though because the toilet will keep flushing until the full sensor is activated and the red LED is on, and the premature amber wont make that happen any earlier.

The 23 DS now uses pressure sensors

This seems like a much better system.
