My wife and I have a new Momentum 351m toy hauler. We are getting ready to take it camping on its' maiden voyage. It has a black tank for the front bathroom and a separate black tank for the half bath in the garage area. I have read and re-read the manual. With the primary black tank, when cleaning, you empty the tank, leave it open and then connect a hose from a spigot to the BLACK RINSE opening on the Nautilus system. You run it until the water coming from the black tank looks relatively clear. I am GOOD with those instructions but what do you do with the REAR black tank? How do you rinse that tank out? Am I missing something? Thank you in advance.

The Momentum 351 drawings show that there is a flush system for the rear black tank. They do not show where this flush attachment is located. Perhaps another Momentum 351 owner will chime in here with more information. If you can find the vacuum break in this usually black braided hose (perhaps under a sink or in a closet near the rear bath?) you might be able to trace that hose to the flush attachment point.

Thank you everyone for your assistance. The flush valve was right there on the side towards the back. We've been a little overwhelmed with all the new features with this camper and that just slipped through my looking for it. We head out today for Misty Mountain Campground in VA for our first trip and are very excited. Thanks again!Jay

Thnkas Guys, but in my old age and eyes I'm just not seeing it. I have a handle just forward of the wheels that when pulled I believe dumps fresh water. But can't figure out the waste water.Ron and Patti Featherston

https://www.youtube.com/watch?v=p9cyrZTXzFA 11:15 mark it appears there should be a white handle to the left and a black handle to the right of the rear jack. These would be the dumps. One possibly for fresh water, the other for the rear holding tank.
Looks like a shadow but I think it might be the handle in the closed position. Capture is from the 11:17 mark.Joseph
