Black tank gauge shows 2/3 when empty
Recently, my black tank gauge on the control panel is showing 2/3 full immediately after I dump. And then it goes to full after just a day or so of use. The last time I emptied was with a pump truck here in the Keys since the park does not have sewer hookups.
Are these gauges in the tanks capacitance or float types? If it was a float showing 2/3 full when empty, I would think it was just a float stuck. But then it increases to full fairly quickly, something a float probably wouldn't do until the tank contents caught up t it's stuck position and lifted it further.
Any ideas for how to troubleshoot, clear or reset the false reading is appreciated.
