No more black tank

Hi I just removed my black tank from my 72 safari and was wondering how do you cap off the top of the valve or do I just remove the dump valve entirely cut the drain pipe and put a cap at the end of the pipe with a hose fitting for my grey water dump into my blue boy? I'll be adding a permanent grey tank under my airstream this summer. I'm trying to get my safari ready for my first trip with my wife out to Sedona, Arizona next month. Any suggestions would be appreciated.

Pretty hard questions to answer without seeing the setup IMO. Is the toilet still in place?

"Just button things up in a neat and workmanlike manner, as a professional plumber would do?"

Now . . .

May we ask what you plan to do with the solid waste material from your human bodies? Seems as if there is no holding tank for your trip?

Maybe I missed something . . .

Did you install a composting toilet?

Composting toilet :)

I'm planning to buy a natures head or airhead composting toilet. No need for a conventional toilet or black tank anymore. I only have the dump valve connected to my shower and sink drain pipes. There's a gaping hole on top of the waste dump valve where the black tank use to connect to.

I have friends with the Natures Head in their tiny house on wheels. Bit of a learning curve but they seem happy with it.

I've spent hours researching the two toilets and they seem pretty amazing to me. Can't wait to try one out. They are a bit pricey though.

Thanks for the clarification!



There should be some kind of mechanical patch/plug to seal that hole in the top of the black tank IMO, available from a plumbing or RV supply house. Because the hole is on the top of the tank, which will be empty, you really only need an air seal, not a watertight seal for liquid under pressure IMO. I would not advise trying to glue/bond a patch in place unless you really know what you are doing with the specific plastic/material of the tank top. BTW -- would removing the black tank gain you more height for the base of the new composting toilet? In the 20-footer thread, someone recently had to do this, as the FC20 black tank height bumps the toilet base up above the main bath floor. [edit -- will find this if you need it]

"Wasteful" Black Tank

If you do not intend to use it and you do not intend to re-sell your Safari, remove it to reduce your weight.

Hey Steve the tank is already removed. The composting toilets are little taller than the normal flush toilets so now the toilet will be flush with my new floor I'll be installing. Now to figure out my bathroom layout.

The black tank is light, maybe 15 pounds.

The black tank supports the dump valve, which supports the drain line so whatever you do you may need to support you may have to support that area.

BTW/ I do have a blue boy but in most situations I still drain grey water on the ground (except National Parks)

I also pulled the black tank out of my '67 Caravel and will be installing a waterless toilet (Dryflush).

Yeah I was planning on capping it somehow and then screwing it into the bottom of the floor with 4 screws.

We also pulled the black water tank out of our 68 Sovereign (31'), and replaced it with a grey water tank since it didn't have one to begin with. Replaced the toilet with a Nature's Head and couldn't be happier. Of course, when "fixing up" the rotted floor in the rear bath of our trailer, it was "rather easy" to replace to pull out and replace the black water tank with a new grey water tank (from Vintage Trailer Supply) since the entire bathroom floor had to be removed and replaced. We made the decision because we simply did not want to deal with all of the "adventures" a black water tank seems to throw your way!!

Gray onto the ground is illegal in any place I have camped. Don't know about out west.

You might also consider a Dometic "Curve" toilet. It is very light and only costs about $125. We only pea in it but it works well for us. If this doesn't work well for you then go to the composting toilet.
