Water leaking out of Valtera dump valve. How do you change out? Looks serious, should I consider replumb of compartment?

There are rebuild kits for the valves. I have a set to go into my two, when I can do a really good clean up. It is suggested that after cleaning with several flushes, that you can tilt the coach to the right to help. Looks to be not a difficult job when looking at the rebuild parts and the exposed valves.

When I empty tanks, I try to get maximum tilt toward the driver side before dumping. On our coach, the tanks drain much more quickly and effectively when the coach is tilted. We have a "third valve" on our waste system. By using a sequence of valve operations, I back flush the black tank about three times with water from the grey tank. The system has appeared to be very effective in flushing the tanks and valves. You can do a similar back flush drill without the third valve by raising the drain hose above water levels in lieu of closing the third valve.

On our 2002 the Gray valve is on the passenger side and can be accessed by going through a small access door. Behind the panel on the driver's side the Black valve sits. As of late the valve actuates but the light never goes off when the valve is closed and sounds like the motor keeps running - although somewhat slower. I believe the valve is closed as the water stops running out of the drain hose.

I know I will have to rebuild the Black valve system soon. Since our drain pipes are a larger diameter than the standard Vantera diameters available, what rebuild kit(s) would I use. I also like the electric valve but certainly see the benefit of replacing the valve with a manual type.

I have looked at the Vantera website and only see the 3" valves and rebuild parts. Can you folks point me in the right direction to investigate repair/replacement options? I would love to also put on a 3rd valve but due to the configuration of the waste pipe through the access panel I do not believe it is possible. (See attached pic).

Thanks again in advance for your input / indulgence.

The waste pipe diameter (Unless something changed from the year of our coach) is 3 inches just like the Valterra fittings. Foretravel used a thetford connector on the three inch pipes. You can cut that fitting off and use an ABS glue to put a new more standard type Valterra fitting on in its place. You can then choose all kinds of adapters and accessories which fit the Valterra standard. From the picture, you already have an adapter to Valterra type fitting connecting your hose.

Carol & Scott,If you have a grey drain on one side of coach and the black on other, I do not see how you can put the 3rd valve in (I have one on too) as you need the 2 close together in same bay. I like having it that way but in reality it is no big issue. I would concentrate your thoughts and energy on other issues that will make a difference to your life on wheels, rather than fret over the small s--t ( pun intended)

Scott, I think that you can put on a third valve ahead of where the termination thetford ring is. It would take a little work to get the old plumbing out of the 90 degree elbow, but can be done and then would need to get a valterra 3 inch valve with the hub and spigot 3 inch fittings and then I would go with a valterra termination ring.

Like Don said, just cut off the Thetford fitting and use ABS glue to attach a standard Valterra fitting. Looks like there would be room to put in a 3rd (manual valve, with handle facing out (horizontal), and still have room for the Valterra fitting and an elbow on your hose. Valterra makes a manual valve with handle attached that is ready to glue onto the 3" pipe, and has the Valterra hose attachment fitting on the other end (that's what I used). Total length (along the pipe) is 4 1/4". The end of the handle is 7" from the centerline of the pipe. so if you have
7" from the center of your pipe to the inside of your door, it will work.

If 4 1/4" from the joint in your pipe (after you cut off the end) gives you enough room for the hose elbow, then what you need is the Valterra T-50A.

Dave, I must be thinking wrong (or something) as Scott said he has one valve on Pass' side and one on Drivers side, so, how can he put in a 3rd one to do what he wants to have it do, which is "back flush" the black tank bottom as we and others do???

@John I'll jump in on this one.

Even though Scott's gray water valve is on the passenger side the outlet transverses the coach to tee into the outlet of the black tank then flow out the common 3" pvc to the sewer dump. As long as the third valve is after the tee the gray water could be used to refill the black tank after the black tank is dumped.

Scott correct me if I'm wrong about the plumbing for your gray water tank.

Ken, thanks for info. I was wondering about that set up as have not looked at that years set up.
Then it would work as staterd, but I looked at that picture and made my comment.

Dave thanks for the Pic and stuff.

Ken you are correct. The gray transverses from the passenger to the driver's side after the black water Y.

Red Tractor - will definitely use the Valterra hose fitting. The Thetford is a hassle.

The waste pipe connections are really packed tightly together. I will have to remove the panel again and look closer. Since Dave K. has been so kind as to provide the product and dimensions I guess I will have to get this done sooner than later. Guess I will have to cut all of that 3" ABS out and remake. ARGH.

Thanks again all.

If 4 1/4" from the joint in your pipe (after you cut off the end) gives you enough room for the hose elbow, then what you need is the Valterra T-50A.

I am planning on trying to add a third valve at the bay end of my system, but my 2002 U270 is set up in a different direction (straight out to the elbow). Assuming I have enough room, how much of the 4-1/4 space will be taken by the 3" pipe inserted into it? 1"...2"...? I plan to cut off the Thetford and then glue on the smaller Valterra, but this is gonna be tight and I want to understand how much room I will need to have from the cut off end of the pipe to allow the bay door to close. Also, there seems to be a T50, a T50A, and a T50C. What are the differences? Does my plan to glue it onto the pipe require the T50 or the T50A? Thanks...

Brad we have got to stop meeting this way. Our 2002s are some times a strange breed. Why would your black and gray water pipes run differently than mine? (rhetorical question)

Well, dang it! Mine comes straight out for some reason. There is a coupling that I can see back in there...but it might not be a coupling...it might be an expanded end (hope not). It looks like I can cut that pipe with a dremel tool and leave whatever length will fit inside the new Valterra valve's backside, then place it so the valve pull is about the 2:00 position. From the very front of the connector/expanded end, there seems to be around 6 inches to the door when closed. It is likely the only way I am gonna be able to be sure is to have one in my hand and see if there will be any interference. My Black water (the one with the cable) has never sealed well, so I am thinking this will solve the problem...without having to take the entire system apart to get to things. Amazon has the Valterra T50....but no T50A. I suspect the difference is on the mounting side of the valve.

I don't think that we will know until the ABS gets cut and is put back together - hopefully.

Next question: Is the Vanterra ID and OD dimensions universal - will they fit on 3" ABS parts/fittings that can be purchased at the Depot or Lowes? As I recall on my set up the fittings are very close together and I might need some internal couplings. I would hate to get this thing apart and be stuck due to the lack of a part.

Guess I will have to buy a Dremmel.

While the 3rd valve is nice for back flushing capabilities, it is also a good safeguard against a failed elec. or cable operated valve.
When I cut my thetford fitting off I bought and twisted together the valve and the 90 degree and the adapterthe got a measurement to determine correct lenght to cut behind the thetford. I have never posted pics on the forum, but will try tomorrow to take a pic and post it.

Just checked my setup, and the 3" pipe can slip about 1 1/2" into the back end (slip hub) of the valve assembly.

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.)

Check out FLANGED VALVE FITTINGS for the slip hub and bayonet, and BLADEX™ WASTE VALVES WITH PLASTI for the valve. If you mouse over the thumbnails on those pages, you'll get a good idea of the relationship of the pieces. Any good RV dealer will either have those pieces in stock or can get them. The page with the flanges also has lots of other 3" elbows, joints, etc.
Probably everything you'll need for tight quarters. This is all compatible with the standard 3" ABS plumbing fixtures at a hardware store.

Greetings
94 u280 2 valves in utility compartment.

I am reading all the posts - still dont understand why for 3rd valve? Can someone point me in the right direction?

Re: Waste valves

Reply #48 – November 15, 2013, 10:39:35 am

The 3rd valve, as the outer most, or last in the system can do a couple of things.

It can still close the system if either the black or grey break, stick, or leak.
It can be closed and allow you to then open the black, and then open the grey, allowing the grey water to back flow into the black tank to back flush. Then close the grey, open the 3rd, and drain the black again. You can repeat till you have no more grey to back flush the black.
With your black and grey closed, you can close the 3rd for a doubly secure way to not leak while on the road. Note, on my 93 U225, I had tank flushers, on the 98 U295 there are no tank flush hook ups.

I bought the removable 3rd valve, as a solution that can be installed if I can not get the black or grey to work someday if they fail "open". I could just clip on the spare 3rd, and head out. Then I can fix the broken valve parts after dumping at the warehouse/shop with tools, lights and supplies. A broken valve sort of ends the use of that tank for the rest of a trip without a 3rd valve solution. In a perfect RV world, none of us will ever need a 3rd valve!

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

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