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...
I've found the sprayer on my 5'er works as designed but the design is poor! It sprays the tank but does not do a very good job of getting things clean. I let the sprayer run for quite awhile until I can see water draining is clear (clear tube attachment on outlet). I then use a King Flush or simply close the valve and run the sprayer filling the tank then draining. Takes 3 or 4 times to finally get everything clean. Sprayer is of little use.
