black tank flush
was just willed a 2003 Montana 5er 3280. This unit has a black tank flush system with it. The Question is how does system work and how can I tell if it did it job.

I have one on my new 5'er but find while it helps it does not do a complete job. I still back flush with a Flush King. With the sprayer I don't have to back flush as many times as I did on my older trailer that lacked a built in sprayer.
