1961 Safari Waste Valve Adapter

I need to replace the old style waste valve in my 1961 Safari. It will need an adapter in order to mount a modern Valterra valve to the existing BW tank.

I also potentially need a collector to accommodate the gray water lines coming in at 90 degrees. I don't have a gray water tank and the original setup has a drain line from the sinks coming in from street-side and a smaller drain from the shower coming in from the front. I don't see that sort of collector available so I'm thinking I may need to tie the shower drain into the sink drain line.

VTS offers an aluminum plate solution for the adapter but the only "review" I've seen is from Frank at FranksTrailerWorks. He believes the acidic tank juice eats the aluminum and will lead to an eventual nasty failure. I'm inclined to trust his experience but I don't intend to leave the tank full. I would only close it while the trailer is in use. But I don't want to have a nasty mess on my hands either.

Also, it looks like the adapter requires the valve handle to be on an angle but I would need it to go straight backward to provide access through the existing hole in the bumper.

Photos are on the attached link to my blog.

Anyone have an alternative, experience or advice for this situation?

Here are a couple of photos...

This is with the old valve installed, notice the valve handle going straight backward to the rear bumper.



And here's the view with it removed.

On my '58 Traveler I am installing new valves but have had the black water tank out. I now have 2 fittings for the discharge hose. Inside I have a way to let the gray water out by itself or divert it to the black water tank with a discharge valve on the tank. Bummer is that the tank is only 12 gallons but I didn't want to add any weight.
Valterra makes an adapter to go from the Thetford discharge fitting to their hose. Here is a link, sure there are more suppliers but this came up on google;

Thanks for the reply. That adapter won't work for the 1960-1964 dump valves. They are "special" and the fittings are not the same as post 1964 Thetford valves.

Plus, my current valve is stuck in the open position (which is better than stuck closed) and needs to be replaced.

I think if I can get an adapter plate made of brass or even stainless, then I should be home free. But I wonder how concerned I should be of using aluminum?

I built an adapter plate of aluminum for my '61 Safari about 10 years ago. It is still working fine, but I must admit I have not inspected it for corrosion since. Considering the condition of the original brass fitting (no corrosion) if you are concerned about aluminum corroding then I would think that brass would be a very good material to use.

Forget the adapter - too much headache.

Instead, engineer your upgrade with modern (easy to get) plumbing. When you look back with 20/20 hindsight, you'll be glad you did.

You lost me on that one Tom. I still need a dump valve, right?

Everything above the floor is original. I've debated getting rid of the toilet and BW tank, and that has it's merits. Then I'd just have to tie the sinks and shower into a common line,

On the other hand, everything appears to work fine as is. However, without a waste valve, if I connect to the sewer I can get sewer gases coming up into the trailer through the toilet. (I've countered that by putting a dip in the waste line like a trap).

Anyone ever tackle this project before?

I have repaired my FRP black water holding tank to accept new fittings. The work was done with polyester resin and a 12:1 scarf. This was allot more work than using an adapter but the ground clearance has to be concerned as well

Here is a link to that portion of the restoration;

Not sure that I would want aluminum in there.

I made my own adaptor, it's been working great for several years and tens of thousands of miles.

Correct!!

If I were doing this project, I'd start with a Valtera dump valve and work backwards with modern ABS plumbing.

For ease of installation, you might need a short hose or two to splice old plumbing to new plumbing. The hose will add "flexibility" when traveling. To obtain large diameter hose, visit your local industrial supplier (hose shop).

Keep in mind, so-called "adapters," if available, don't always work as intended.

Success!

It took quite a bit of "figuring" but I was able to get an adapter made by a friend of mine and install a new Valterra valve, collector and tie in the two gray water drains.





You can check all the details on my blog.

Nice work!

HandyDan:

I tried to post the below reply on your Blogspot but could not figure out which "select profile" I had to use to get it to post there, so I'm posting it here instead.

Your Blog shows, with a greater number of photos than here, a wonderfully imaginative solution with a clear, straight-forward well-illustrated explanation of it. Nice job adopting a brand new dump Valterra valve to the original black water holding tank in your 1961 Sarari. Dump on!
