Natures head with urine diversion install: 310 motorhome

[Magnet18]

Posting up my install in pictures here

Guess I didn't get a good "before" picture that I can find, first picture is the old toilet and false floor/wall removed, showing the black tank (it sits half above and half below the floor)

Second picture is the black tank after modification

Third picture is a close up of the plug, I drilled a hole sized so the pipe fitting would thread in, then sealed with 3m marine epoxy (I am not a plumber, open to suggestions)

And the new false floor

More marine epoxy (I am not a plumber)

Mostly finished with the construction, still finishing work to do. Need to spend a day with the sheet metal tools, and a flooring install if the whole airstream is planned

The vent pipe for the black tank needs extended, will be doing that plumbing as part of the washer dryer install

I also replaced my dump valves and plumbing when doing this. A third twist-on dump valve at the outlet allows the tanks to be shared, since urine volume is small, effectively adding grey tank space

Another finishing touch, a support bracket to help stabilize things now that the front bucket is gone
Highly recommended, as without the bucket it was a bit wobbly

I'm going to be doing something very similar to your set up.


Your pictures were very helpful.

Glad it was helpful, that was my hope!

Nice install. Another option for bracing if you want a facia covering the diverter tubing is to reverse the urine bin. A little more tricky to reach the lever valve if using one although there is a gap you can see to reach underneath. I used a furniture leg under the upside down urine holder for additional front support.

Simple and it looks good!
I still plan to install the bucket upside down for looks, though I wasn't sure how well it would support so i went with the total overkill bracket

You'll have a very secure setup for sure!

A much overdue update, just some finishing panels, finally moving the project from "half done" to "done!"
