Black Water Tank Valve Open but no Flow...

I have a problem with the blackwater dump valve. The valve handle opens but the valve us apparently not open and I am not able to dump the tank. Any suggestions on how to proceed. I have read numerous threads but none match my problem yet. I'll keep searching in the meantime. Thanks. I have a 34 ft 1986 Excella

Hello. You might ha debri clogging the outlet by the valve?? Unless you are sure. Can you pull the handle all the way out of the hole? and are you sure the valve is closed. I fit is debri , I have simply dumped a bag of ice down the camode then drove around with it in there. That will break anything up then it will simply turn to water as ice melt and dumps easily.

On mine the valve handle attaches to the valve with a threaded rod. I was able to reconnect by just turning the valve handle clockwise to engage the threaded rod.

Seems to me that your options vary widely, depending upon whether your tank is full or empty at this moment. If empty, you can simply disassemble the valve and figure it out. But it sounds as if it's full, and if so, that's a whole other set of issues. If it's simply a matter of the valve handle coming unscrewed as Lumatic suggests, that's an easy fix ... seems to me unlikely that debris would prevent everything from coming out of the tank ... some liquid would make its way past most any "normal" clog, so I'd bet that the valve itself is just not opening.

My options appear poor. It is 3/4 full and the valve handle in the open position with no flow. I have flushed back and no flow, I have disconnected with the valve handle in the open position and no flow. It is obvious that the valve did not open and my options limited. thanks for responding.

I got my problem solved. It was debri stuck on the sensor. I tried to view the tank through the toilet and it seemed full and my level indicator on my board reflected a 3/4 full mark. After I opened the valve and no flow came, I did what we are not suppose to do, opened my gray tank valve in hopes of flushing whatever might be plugging the outlet and shut it off immediately. This produced a flow from the black tank. I then decided to use the wand to flush it out and with a flashlight I could see that the tank was indeed empty but whatever was on the sensor was causing the bad reading. It is now clean and sensor working reflecting an empty tank. Thanks to all who responded.

I have this same problem

My blackwater tank valve is in the open position but nothing is flowing. I can tell the handle that releases the trap door to let out the blackwater is not connected to the sliding trap door anymore. I tried to see if the handle could screw back in, couldn't get it. Now I am stuck with a full blackwater toilet tank, the place is starting to smell and I live in the trailer full time, Please help. I don't know how to fix this problem because the tank is full.

Thanks
Sean

I am having the same problem today with my black tank valve. It feels like it opens, but I do not believe that it is. I hate the thought of having to take it all the way to my RV repair, but I have to assume it needs a new valve. Oh, and the tank is 1/2 full. Great.

What you are going to have to do, if the valve will not open is take the plumbing to the dump fitting off at the valve assembly. Then get several 5 gallon pails, (if you have clearance for standard 5 gallon pails) enough to catch the effluent that is in the tank, plus 1 extra, "just in case". Then you can pry open the valve from the inside of the sewer pipe and empty the tank. Be sure and wear rubber gloves and goggles when doing this. Yeah, it's going to be a messy operation.

If you live out in the country, you could also dig a hole and let the crap go into the hole and bury it. Yeah, I know that is not PC, but sometimes you gotta do what you gotta do in an emergency.

I'm haven't seen one of the slide valves used on an AS close up, but if the problem is that the threaded metal rod has stripped out the thread in the plastic sliding blade, might it be possible to screw in some sort of self tapper screw tack welded onto a a rod and get enough purchase to pull the valve open - and the of course replace the valve with new.

Just a thought. I have no idea, it may not be practical. First thing that came to my mind though, it sure would be nicer than the alternative if it had any chance at all of working!

I have often wondered myself how to cope with such a situation if it ever happened to me - I live in fear every time I pull that handle!!

I have almost become paranoid about it! No idea if it happens often though.

Brian.

Ah, well, maybe you could purchase yourself some of these gloves and go at it from the outside:

You may be able to siphon or pump out the black tank up through the toilet. You will not be able to remove all the sewage but it would reduce greatly the 'flood' when you are able to open the valve.

Loosening up the valve slide thingy

My problem is somewhat easier, the 1972 25' Safari valve is open and it looks like it was left in this position over the years with the gray draining and the black not being used any. Its a horizontal slide with the drain being vertical in the rear of course. I'm thinking on closing with a cap with the hose male on it and filling the system up into the toilet area and then let things set for a while. After a day or so dump through the hose drain and see if I can loosen the slide. Is it okay to use WD-40 on the slide area?
