I didn't buy the T50A, but assembled my valve out of 3 separate Valterra parts I found at an RV store:

The back end - Valterra T1005 3" slip hub with valve flange, the Valterra T1003VP Bladex valve, and the Valterra T1009 3" bayonet (that the hose attaches to.)

Perfect! Thank you and Kudos to you, Dave.

Dave thanks! Understood.. i have been back flushing with just the 2.

Can I just put the 3rd valve on the existing connection?

Yes you can, as I intend to do. I first looked at a permanent 3rd valve, but the 3" line is sloping downward and I just did not have the 1/2" of room for it to fit above the bay floor inboard. Not wanting to rebuild my pipe system changed my plan to a removable 3rd valve solution further outboard.

I just ordered the 3 parts to make my valve from Amazon! I'll just carefully make sure it will all fit in, and at the right angle, to allow the door to be closed and the handle fully extended. I got the T1003VPM with a metal handle. I plan to let the leakage drain, shove a rag into the hole, cut the 3" pipe, install the combination, pull out the rag, close the valve and never have to get messy again. I will make sure to mount it with the idea that I will be able to replace the seals on this setup and never worry about the Black and Grey valves leaking!

Brad,

When you get ready to work on the valves, lean coach to driver's side to drain as much as possible. Then lean to passenger's side and begin disassembly. Doing this, you should not get more than a few drops in your work area.

Brad - I will be waiting for the positive progress report.

Thanks for the tip, Brett. Parts are due Tuesday night (always 6 PM or later UPS deliveries here).
I got lucky in that Amazon had one the T1003VPMs in stock as a returned, open item...for $7.98...about half off. I snatched it up, so this is a less-than $20 cure.

Yep, all parts are available from RV dealers (or can be ordered,) or most or all can be ordered from Amazon as Brad did.

Also might mention that the 3rd valve is great at back flushing debris from the bottom of the gray tank too. AFTER you back flush the black tank empty both gray and black tanks. Use your black tank flusher to fill the black tank with fresh water. Now close the 3rd valve open the black valve wait for the air to clear out and then open the gray water valve. I was amazed at how much crap came out of the gray tank the first time I did this.

BTW: when you plan your 3rd valve try to leave room for a short section of clear pipe so you can actually see what's coming out. It's a little ugly but nothing like visual confirmation.

see ya

That's a GREAT idea! Thanks. I imagine there may be some soap scum or small kitchen debris in there after 11 years. I do love that black tank rinse feature on my 2002!

I use a Polychute hose that has sight glasses at each end of the hose. There are also clear extensions, angle couplings, and back flush units that can be added to Valterra fittings during the flushing process to show the effluent. I find that the effluent from the black tank is as clear as the grey water by the third back flush using the third valve system.

We don't have the fancy shmancy tank flushing systems that you folk with those "expensive new" coaches have.

Removed top panel to get a look at the valves , does anyone know how the valves are fixed to the 3" pipework . I can see on the new valves that one collar is male and the other female ,are the existing valves glued to the pipework ??
That would involve replacing all the pipework ??

Ok found my glasses and can see that the collars bolt to the valve .

Managed to get new valves and cables installed yesterday , changing the cables proved to be the toughest part as the lower panel needs to be in place , forcing you to work over the top of it . Fingers crossed and thanks to everyone for advice

Changed out my valtera grey valve,had to cut off bottom bolt with cut off saw. Greased with home depot plumbers grease, installed fernco coupling just in case it has to come apart again, very tight area, RV plus had all the adapters & valve. Thanks John

I finally cut off my white connection end, shortened the black pipe and glued on a new Valterra end connection. I turned the Valterra slightly so that my new twist on 3rd valve does not get in the way of the shore power cord. So if I dump and have a problem with either the black or grey valve I can simply install my 3rd valve and work on things when I get back to the warehouse. Also I can now back flush if I want to, and can now feed the dump hose thru the bottom flap opening, with the bay door closed. Still left to do is install the rebuild kits for both valves.

Got my permanent third valve installed. I oriented the valve pull horizontal and to the rear, so it won't be in the way opened or closed. While in the area, I am cleaning up the bay of all the sloppy and dirty tcaulking and adding a momentary switch to turn on the water pump so my 270 can have another 320 accessory.

Congrats Brad - could you post a pic of the finished job?

Here is the finished product, both the new valve and the added water pump switch. Since it is so easy to add to the water pump relay circuit, I added both a new switch and a new indicator light while I was at it. I used a Dremel cutter to get the old Thetford off and it was an easy job to get the new Valterra base on.

Nice job - hope mine comes out as well.
