Hope someone can set my mind at ease. I have a 2014 Arctic Fox 5'er and have had it out a couple of times. When I use the Black Tank Flush I'm not sure if it's working. I can hear the water running...
Do your draining and flushing then open the potty flush valve and smell. If it stinks... flush some more. I always leave the contents in the tanks til I get home so the waste can break down as much as possible. I have a clear connector on the drain pipe and I drain and flush til the water is clear plus about one more minute. My tank has NO smell when I'm done. Craig
