2018 fuzion 371 rear dump issues

Russo · 07-15-2021, 03:45 AM

Purchased a used 2017 371 and cannot get the rear bath to dump. It had 2 bars when we bought it but I thought it was just paper on the sensor. We used it a few time and it went to 3 bars. I have pulled the handle in the convenience center up front with no luck. I have been under the unit and do not see a valve handle for that back tank. The manual did not say anything specific. Does anyone have any suggestions? We are about 4" from the toilet pipe and looking for solutions. I tried to take the belly cover off but snapper every self tapping screw so need to buy a box so I can take that off if needed. Any suggestions? Is there something in the bathroom or a hidden handle someplace?

Look near left rear tire, in the wheel well and there should be a black tank dump for the rear tank.

Been under there I see the pipe that runs over the axle to the Y from the front pipes but no valve body or handle.

The handle may have fallen off. Look for a hole, often with expanded foam around it.

Thanks, I'll double check again after work and see if I notice anything like that. If anyone has a photo of theirs it would be helpful on where to look exactly.

Not the same model, but I doubt they changed too much. This is along the frame rail, effectively out of sight to the casual look. If the handle is gone it would be hard to see.

Thank you I will look at that location tonight. That is helpful. I was tracing the pipe,never thought to look IN the wheel well for the handle.

Ya, that one is ahead of the wheels, behind the slide. If the slide is in you can reach it ( if you know where it is). If the slide is out, you are on hands and knees crawling around. I carry a foam garden kneeling pad.

Thanks again, hoping that is it. Dealer made no mention of this during the walk through, just showed the 2 handles in the convenience center . I'll just say I was hot when I could not dump my tanks the other day. I have put a bunch of enzymes in thinking that was the problem. Cannot wait to get this emptied.

Just FYI! Those enzymes in a rv tank don't help much, they typically take 30+ days to do the job. Granted they won't hurt anything & the septic/sewer system you're dumping into could probably benefit from them.
As for the sensors, in 40+ years of rving I've never owned one that the sensors were anywhere near accurate past the 1st tank full, never paid them any attention. Dawn dish soap & fabric softener are about as good a tank cleaners out there, but don't expect anything to help the sensors too much.

I have a 371 the back bath dump valve is behind the middle Jack.

We purchased a new 365MB in May. They didn't tell us about the handle for the kitchen sink. It's hard to reach, I can barely get it without getting on my knees. So wish they would have told us. but we went looking for it. Plan on trying to find a work around in the fall after we're done camping for the winter.

Good Luck!!
