Okay, so this is mostly my fault. The dealership that we bought our fifth wheel Montana from said that they would do a walk-through during delivery and expect it to take about two hours. That walk-through lasted all of 15 minutes. Obviously, having never owned an RV and that was not a sufficient walk-through. I did complain and somebody came out and did another week walk-through. This is one of those situations where you don’t know what you don’t know. I had no idea what questions to ask. I’ve taken it out once and it wasn’t a pleasant experience because we had one of the worst storms in a while that lasted for three days, so I basically just sat in the RV and watched TV.
Since then I have educated myself about a lot of things but the one thing that I haven’t done yet (please stop laughing) is flushed the gray and black tanks. Where I took it to did not have sewage at the sites. No I’m getting ready to take it out again and I know I need to flush those tanks, and where I’m going to flush them is not an issue.
I am reading through the 2019 manual (which infuriatingly gives very little information and just tells you to go to the vendor site of the device you are wondering about)
There is a section about the no fuss flush option and where it supposed to be and how it supposed to be labeled. I have a hose hook up that says “tank flush“ with a caution above it it says “do not use unless the full Way termination valve is in the open position“.
I have no idea what this connection and functionality is for.
I’m also looking for information on this a switch that says “tank fill power flush“ and has a switch that says either “normal flow“ or “Fill”.
I'm ashamed to admit I know nothing about flushing my tanks
