I can drain the black tank one day and the gauge will show 2/3 to full the next day. I also noticed that the water level in the commode is lower than it used to be after flushing. Have any of you experienced this because I was wondering if my valve isn't shutting off completely and letting water slowly fill the black tank? I am thinking about cleaning it real good and then taking a paper towel and running it around the inside to see if it gets wet. Thanks Tom
