well, I don't know. could be easier to rinse out the 3" one. Considering that many dump stations have intentionally limited the ability to connect to the water supply, and leave a stub of hose with no fittings on it. Its hard to get water directed through a 3/4 hose without being able to "connect" it to something. not hard to get a stream of water from a non-threaded tap or bare hose to thoroughly rinse a 3" hose.

the point being that in any case, with watever transfer method you're using, you need to be able to clean out your hoses, and the water with which you do this must go directly to a sanitary collection facility...Which means that you either have to be AT the collection facility, or near it. And you'll also need some form of running water.

Chuck:

Check the geometry with hooking a 30-gal tow-behind tote to the discharge on a 2000 30' Excella! You have to discharge into the top opening on the tote and with most slinkys that involves a failrly high loop from the vertical discharge. The "invert" (---bottom of pipe) of the trailer discharge connection - and the top of a 30-gal tote are fairly close to the same elevation - with the tote winning out in most cases. By the time you configure a 90 deg elbow you're about back to where you started. That said, the discharge height remains the big problem. I've considered discharging into the "discharge" of the tote - but unless you tilt the tote onto its' side (---after carefully disconnecting from the trailer) and bleed the line into the tote, it's still a problem.

C'mon people - help me out!!! I can't be the only one that is "dumping challenged!"

yeah, I'm hip. I've got a 25g tote, and sometimes that's a tight fit to get under my trailer....and my "exhaust pipe" is probably considerably higher than most, because its right at belly-pan level. The black tank is on the floor of the trailer; pipe comes straight down vertically, with only the bayonet-lugs protruding out the bottom of the pan. I've seen the way the plumbing hangs down precariously on the new units, and I can't help but think that you're all just one pot hole away from a catasrophe!

But this goes back to my earlier point, that the blue tanks really weren't meant for this. Sure, you can do it in a pinch, but I wouldn't as a matter of routine. there's just no way to fill it without having to deal with some sort of "residual". residual soapy-water is no big deal; the other stuff...not so much.

So my general rule is that the size of my black tank limits the length of my stay in one particular spot. I can get about 3-4 days comfortably with my tiny 13g tank; Longer stays require a full hookup site.

Mr. Hanky Strikes Again

You know something that just confuses the heck out of me is the design of the gray tank system. Why the heck doesn't the gray tank serve as the crapper's supply tank? The only thing more efficient than recycling is REUSING resources.
Adding "the captain's log" to gray water makes more sense than polluting completely pristine water with it. The gray tank could be smaller too because much of it's water could progress to become black water.

As I see it you'd need to add a small pump that would sump water from the gray tank to the toilet and have a T fitting with backflow protection on the freshwater side and some kind of pressure sensor that would use fresh water if the gray tank was empty.

I'd be afraid that it would clog often with the debris you still can have in the grey water tank. You'd have to filter it, and have a place where you could easily clean such a filter. Otherwise, an interesting idea!

Paula it can and has been done...

Thetford makes a recirculating electric toilet...I haven't quite figured out the reciruclation part and not sure I want too

I have actually help build a house where the gray water water was used to flush toilets and water lawns. It basically had a holding tank with a pool skimmer type filter on it. Worked great and kept the guy's well from going dry in the drought season. When he was forced to hookup to city water it really PO'ed the local utilities, because he was running the fool out of his sprinklers...and his meter wasn't moving...they must have replaced that meter 4 or 5 times one summer It is very doable but the cost and inconvience of such as system probably would out weigh the benifits...and believe me I am considering it...the gray tank on my 31' is only 10 gallons...and the racoons can only drink so much gray water after dark

Reusing wash water would work well if only the shower and bath sink went into the wash tank and not the kitchen. Alot less flilter changing especially if a sump filter is on the input line in the wash tank. I wouldn't connect into the fresh water side. Why take the chance of contaminating the system with bacteria that swim up stream when you can just run the shower to charge the wash tank if empty. In considering this the tank sizes switch from a larger wash tank and smaller black tank to using a larger black tank and smaller wash tank. I'm looking at two 35 gallon tanks or a 35 and a 55. Now 55 gallon is alot of black water and you don't want to screw up. A wye value to enable direct transfer from the wash to the black should it fill and for rinsing the black when dumping is also include in the current design. Electric mascerator head and mascerator pump for emptying the black tank with a one inch hose. Finding the one inch hose and hardware is presenting a challenge.

we've installed a macerator on Vintage Thunder in the past two weeks. I'm doing some testing now to see what it's good for, and how well it works. I'll post updates on the blog in a while. http://www.airstreamlife.com/vintage...underblog.html

RE the Sewer Solutions - Is there an issue with connecting to our famous (infamous) Thetford - or is it Valterra - connections? Anyway, whatever our non-standard fitting is - can the Sewer Solutions rig work out of the box, or do we need to find an adapter?

Thanks - Pat.

you need an adapter. I believe it is the "valterra universal adapter".

Sewer Solution caveot (sp?)

Paula - I LOVE my SS, however, be aware that many dump stations do not have a screw on male adapter on the water spigot - not allowing one to hook up the hose that makes the sewer solution work with the black tank (I can dump my grey tank fine).

I get around this at campgrounds by leaving late, and backing into a full hookup site with water to use my SS. None of the campgrounds that I've visited have minded. However, this summer when we travel to CA, I will get my own stinky slinky to use at CA SP's. Arnold has apparently turned off all utilities at the state campgrounds (boondock only).
I really like my SS (I got one of the "blems" too - no problem's!).

Marc,
We carry a little gadget called a Water Thief they work on just about any type of faucet and with a hose clamp will even work on a short cut off piece of hose So far if there is water running out of the spigot...I will get what I need

Sewer Solution

Got the sewer solution and am using it. Love it! It really does drain on the level or uphill!

I did get an unpleasant surprise at a campground where I was staying when they said it was illegal to hook a hose into any white water and then use it - even with a backflow preventer - to rinse the system. I did think that could be a bit unasthetic myself, so I had already rigged up a plastic bucket with a drain that is a female hose connector and added three feet of hose terminating with the Sewer Solution's quick connect valve. Works fine to rinse the hose. I just hang up my bucket, fill it with a waste basket full of water and let it clean out the hose, etc.

The key with this system is that you can leave the gray water open all the time, but you only drain the black water every two or three days (no lumps, no clumps). I've found that while camping I can just drain the black tank, then fill the toilet bowl and flush a couple of times and the hose will be running clean without even hooking up my little flush bucket. I'll use the flush bucket when I'm breaking camp, and possibly even put a bit of bleach in the line to make sure I have a pristine hose. This will store in the rear bumper in a fraction of the space a slinky takes. I'm just going to find a plastic box to keep it separated from the electrical cable. (Can anyone tell me why it is ALWAYS raining when I have to break camp?)

Ordering it was great timing, especially since my slinky sprang two pinhole leaks. How did that happen with a slinky that's less than six months old?
