Combination Grey and Black Tank Idea!

[A-Merry-Can]

I'm still a little ways out on making a final decision on this, but I thought I'd put it out there for opinions. On our little 1959 18 footer, I have dropped the idea of a wet bath and a shower all together. there's just not enough room, and with wood panels on the walls, I thought it too risky.

So, that got me thinking about simplifying the plumbing as well. Instead of a grey tank AND a black tank, I think I'm going to combind them into one larger tank. I have a 27 gallon tank that I had originally planned on using as the grey only. The plumbing requirements are now 1 sink, and 1 toilet. In looking at our potential use of this trailer, we don't plan on "soiling the throne" unless it's an absolute emergency, and the lack of a shower greatly cuts down on grey water. When I get to the actual plumbing part, I thought i might install a valve that would divert the sink water straight to the ground (for when we're at home or whatever, then divert it into the extra large grey/black tank when at campgrounds.

It seems like the perfect solution for a shortie with no shower. On my Globe Trotter Project however, we'll definitely have separate tanks, due to the shower and extra sink in the rear.

Thoughts?

Cheers!

Huh? What? You mean there's a choice?? I only got a combined tank in my '84. As it didn't come with a shower I'm sure that's why AS did mine this way. I vote for a combined tank without the diverter to the ground. KISS.

Here is a picture of a gray and a black tank on a 1957 bubble, thinking about going this way. Black & Gray Tanks Discharge. View of left tire, leaf spring, grey tank to the left, black tank to the right.

Did your coach have a shower? I can't remember seeing one at the rally a few weeks ago. loosing the diverter isn't a bad idea. I just don't see the benefit in putting 2 tanks in a unit with one sink and one throne. On a positive note, the black tank would always be hosed out! ha!

Does your bubble have a shower? i can't remember if they crammed one in those little guys or not. what would the total capacity be of both tanks?

Why not get rid of the toilet and use a Porta-Potty? This way, no black tank would be needed. "Mac"

hi jp- your idea sounds like a good one to me. I did what you're talking about on my '72 re-model: I have no bathroom sink, just a toilet and shower pan. The shower drains directly out, but for the kitchen sink there is the option to let it also drain directly out or divert it into the black tank. I thought this might come in handy for wal-mart overnighting, or just to add water to the black tank to help in flushing it out. Anyway- good luck with your project, hope these ideas help and will enclose a pic of the diverter arrangement. -tim

We rented a new 4 winds class C in Alaska two years ago. Much to my surprise, both sinks drained into the black water tank. I found out when I pulled the plug on the bathroom sink and it didn't drain properly. I stepped on the toilet flush and up it came. Fortunately, our site had sewer, so were able to dump immediately. Only the shower across the hall drained into the gray tank. From then on, we dumped every two days.

If I were looking at buying something like this, it would be a show stopper.
