Grey Tank Troubles

[Robin97396]

Sounds like a good plan.

I also plan on using 2 grey tanks as I don't have the room underneath for a single large tank under my E350 van bus.

My tanks would be the same size and mounted at the same level, connected together and both vented, so they basically will fill evenly. Sink would drain into one and the shower would drain into the other, but they would even out on there own.

2 different size tanks could be tricky if the large one is mounted higher it would fill the smaller tank and back up into the drain and any sink connected to it won't drain.

How would you go about connecting them?

That sounds like a pain while draining them, waiting for the tanks to equalize.

I wish I had tanks.

I was looking at 30 gallon tanks on Ebay they have two, 1 1/2" openings, and two 1/2" openings.

I would connect the bottom 1 1/2" drains together into one drain using pvc pipe.

The drain pipe I might make larger, But I want to have a valve on the end with an electric solenoid (like a inground sprinkler system)
I am also considering having valves to isolate the tanks, as one will be hooked up to a sink & composting toilet for urine only.

Still working out the plan in my head.

In theory they should equalize on there own, but if one drains before the other it really does not make it any harder.

When I had my other Rv's (travel trailer, a class A & a class C), Draining the tanks were a task;
---Drain the black, partially refill and spray to rinse & re-drain the black, drain the gray, then clean the drain hose, also when I arrived home sometimes the black would need further cleaning.

With two grey tanks, I can just leave them open at a campground, or on my own land, & also drain them on my gravel driveway, The compost toilet will handle the solids.

In my mind this is easier, simpler & better & faster.

You know, if you save all your urine for a year you can make gunpowder! Well, actually you can make saltpeter which you could use to make gunpowder.

That thought makes it pretty disgusting that the army supposedly used to put saltpeter in the chow to make guys less... rambunctious. I can only hope they mined that saltpeter.

I would prefer to piss out the back door, but some people might get offended by that.
I don't like saving urine, every other animal pisses where they want, but if humans do that, we would get in trouble

In a bus if you piss out the back door, you really can't see what you're doing unless you're really short. The front door is a different story, and comes in very handy when it's raining really hard. You ever been going down the highway and suddenly had to pee and you know you can't make it to the next town. Pull onto the shoulder of the road, open those front entry doors and let er rip. You don't even need bushes as long as you don't step out of the bus. Not for dribblers.

Obviously I don't have a bathroom, or a jug. Never saved my pee or had any use for saltpeter. Who knows when we might need to make our own gunpowder?

In my bus I can see out the back door whilst relieving myself. That ten inch raise made all the difference!

If I can't figure out how to make the grey tank system work with the 55 gallon tank, I could probably do it with 3 30 gallon plastic barrels. I could definitely fit them all (with slight body modification), and we have a million barrels laying around. It'd be more plumbing but it's still way cheaper than buying a $500+ grey tank. I think that would solve the uneven filling problem and give me 5 more gallon capacity. I dunno, maybe I'm just thinking about it too much

[Robin97396]

Grey tanks are offered all the time by motorhome dismantlers on Craigslist, but you've probably already gone there. These plastic barrels are great, and they're so cheap.

Get the steel cage that goes around it also. Mine is held in place by six bolts.
