How to flush 2nd black holding tank

[Xmatney]

I have a 2017 High Country 362RD. I need to figure out how to flush the
second black holding tank? I have racked my brain and can't figure it out. I have 2 bathrooms so I have 2 black and 2 gray tanks. I can't figure out how to flush the second tank. TIA

Do you have 2 separate tank flush connections? If not I think only the MAIN bathroom would have the flush out.

You can install a tank flush aftermarket on your own. I haven't done it but know some that have and they work good too.

Or you can stick a hose down the toilet.

If I have a second one I don't know where it is.

I flush both black tanks with a hose down the toilet, every other dump and when the rig is stored.

If you only have one flush connection in the service center the you need to use a hose or you can buy a flush wand and go right down the toilet. You could install another tank flusher there not hard to do it yourself.

Just install one of these. https://www.amazon.com/Camco-40126-T...tank+flush+kit

I just use a back flush gadget like this** or the back flusher on the macerator, depending on how my sewer hook is at a campground. I've found the macerator version works much better then the built in arrangement or the Valterra/CAMCO

I also made up a flusher to shove down the toilet from an old hose cut down to a manageable length with a l90 degree awn sprinkler head clamped on the end. That one works well too.


If it's a straight shot, no angle to the holding tank, both Valterra and CAMCO make a wand to shove down the tank. Unforunately our HC has a 45* tank run, which is why I made the one noted above
