I have a 2010 Keystone Outback 282FE and the black tank valve wont close all the way causing black water to seep in the main dump line. Any thoughts on how to correct this? I have a enclosed underbelly and really dont want to cut a hole in it but I'm afraid I'm going to have to. It has always worked fine until now when I tried to drain some gray water and discovered it wasnt all gray water. staying in a National Park in AZ at this time and dont want to make a mess on the ground. Any insight would be greatly appreciated.
Thanks

One thing you might try. Buy a can of silicon spray. Empty tank and take off sewer hose. Spray a bit on shaft, and then spray half a can up the waste pipe while operating valve slowly open and closed. It has worked for me for years when valves get hard to move, so it might fix yours. Certainly worth trying.

Most likely cause is some TP or other debris jammed in the groove where the gate valve slides. When you can get TO this area it's a very easy fix to usa a length of wire to clean out the groove. If you can't get to the groove to clean it it may be necessary to remove the belly pan.

I see no way of fixing this without cutting into the underbelly. You are going to have to remove the valve and clean out the groove. Another alternative is to get a valve that attaches to the drain outlet. This will allow you to remove the cap and attach the hose without anything draining out. These are available at most RV dealers for about $25.00.

Thanks for all the responses. As soon as I remove the cap outside I have ( well you know what I mean ) flowing. I just hope when I go to the dump station and use my built in flushing system it will clear. BOY AM i EVER GOING TO HAVE TO BE FAST HOOKING UP THE HOSE. I just hate this part BUT I guess it's all part of the adventure.

Thanks again

As a preventive measure, after I have dumped, and with the black valve still open, I always flush the toilet a few times to make sure nothing is in front of the valve blade before I close it.
Here is one thing you could try:
- Fill the grey tank with hot water.
- Pull out the sewer hose but put the cap on the end so water can't get out.
- Open the grey valve to fill the hose with the hot water.
- Close the grey valve and open the black valve all the way.
- Lift the hose in the air to force the hot water back into the black tank.
- If you can, let it stand for a few minutes, then try to drain it.
This will obviously have to be done at a dump station because when you remove the cap and lower the hose, it will start to drain out. You can just remove the small cap so it drains slowly.

Good luck ...

Hi,

Once you get dumped, look at the valve - most of these are held together with four screws...not too hard to loosen things up to clear what's jamming things up.

Another "solution" is a twist-on gate valve -



They simply lock on instead of your hose and give you a valve in front of the waste. They are around $20.00

Before I'd cut the underbelly, I'd find out which one of these would fit, then buy it, use it and not worry about it.

Works for me, but my leak was more of a seep.

I would also put the extra valve on and forget it. It is probably a good idea to have one even as a back up because **** happens!
