Black tank valve and cable

I have a 2014 Cedar Creek 34 RLSA and the black tank cable is getting more difficult to pull and open the valve. Just a matter of time it will break. I really don't think it is the valve itself. I use the cocanut oil lube every few weeks. The other two gray valve cables aren't nearly as difficult although they have gotten harder to pull since two years ago. I have sprayed the cable with Boeshield just near the handle so the entire cable is not getting the lube.

How difficult is it to get to the tank valve to replace the cable? Any suggestions would be appreciated.

Have the same situation with the black tank handle in my new Silverback 33IK. Will be looking for suggestions.

Same problem with 2014 36ckts. I read an article in Trailer Life magazine about drilling a small hole in the top of the valve and injecting a lubricant, working the valve until free, plug the hole with a small screw, then all should be good for a while. I'm going to try this in the spring when I get "the fever" again.

Our 2015 38CK is in the shop for some warranty work right now and that problem is on our list to fix. The service gal says they are putting longer cables on to correct the stiff valves. Sounded like they'd dealt with this before this way.

I had that same problem a few years back. Couldn't close the black water valve at all. Luckily I had an end of line valve, so I could still dump when I had to. Long story short, there was 75 miles of cable ( ok I exaggerate) under my underbelly covering. I took it to my dealer, had to order new valves(never used) for the cable. New, shortened cable was installed. The problem was that there is an inside sheath that the cable runs through and it ended up binding, therefore not allowing the cable to move. Ended up having the same problem with the gray water cable for the bathroom. Took it to another trailer mechanic that I found and like doing business with. He told me that the valves actually face the door side of the trailer, which doesn't make any me. He managed to turn the gray water valve towards the driver's side of the 5er. He also got rid of the cable and drilled a hole through the frame and installed a rod. Works much better and will do the same for the black water valve if and when the time comes. Worked for me.

I also was having this problem with my cables when pulling/pushing the handle, so I took it in and had the cables replaced with rods. Now so much nicer and easier.

If you have the segmented plastic belly panels. Remove the 5 or so screws along both seams of the piece of belly pan near the main drain line. Bow the panel down and remove. On the street side, push insulation aside as needed and you'll be looking right at the grey tank dump valve. As you'll see the cable makes a big loop and just lubing the exposed cable pull will probably never get lube end to end. The Trailer Life magazine article has merit, but I found the actual blade of my dump valve was sticking more than the cable. I removed the whole valve, disassembled, lubed the blade with Parker ORing lube, reassembled. Works great.
