Black tank dump handle sticks

Good morning,
Thank goodness for this forum. The black tank dump handle is VERY hard to pull out and push back in. Does the shaft run through a long casing to the actual gate? If so can it be lubricated?

Some have cables.
If it is just a push pull rod it's possible the gate valve is partially obstructed.
It may need to be removed and cleaned.

There are numerous black tank treatment additives out there and some with valve gasket lubricators. Might give one a try. Also, a little WD40 on the pull shaft might help.

I hope yours works out better than mine. Ours started just like yours and the end result was cable replacement. Very Important DO NOT TWIST the handle as you pull it. some of the cables are braided so the twisting will cause the cable to open and close hard, then mine broke.

This is a chronic problem. After two cable replacements I installed an electric valve. No more problems.

Similar Black Tank Issue

I had a similar issue that began about 1 year following our purchase. The valve was very hard to open and never closed fully. I attempted the valve lubricants with no success. Had to have the valve and cable replaced. Both were 'corroded'. Not sure how that occurs other than storage of material prior to installation. 2015 - 36 CKTS.

Ours have been hard to open and close from the first day we bought it new, WD'd the shaft when it was open and it helped a little , where did you find the electric valve from and how hard was the install

tank dump handle sticks

I had mine replaced in my 2015 29re. Impossible to open and close. It was very hard to get to. Up against the frame. New valterra works great.

Possible work around for you

My 'new to me' fifth wheel had a very hard for me to operate black tank valve. Good friends spent a lot of time trying to lubricate it for me while I researched on the various forums. We ended up leaving the original valve open and adding on a Valterra twist on gate valve that I will be able to replace later if necessary. So far it appears that the black water will not over flow into the gray tank as long as I only open the gray after the black is empty. Here is the link to the main part (I think there was another part glued on so that this can screw onto that)

I agree with Bubbles....get some lubricant into the black tank so it'll do its job. Also,,,,I pull out the handle and apply waterproof grease on the shaft. Also,,,,are you using regular toilet paper.....that can cause problems with the valve opening if the TP is sticking in that area.
