Black tank gate valve

[Zerogainman]

How do you keep the black tank gate valve lubed? Very hard to open and close. Would rather not replace. I have a 2015 grand design Solitude

When mine got hard, I used a combination of PB Blaster & Zep 45. I pulled the cable into the basement, squirted a lot down the shaft, propped it up on the ceiling overnight. Rerouted the cable for lazier bends, put it back & started working it back & forth. Repeated this a few times. It's not perfect, but much better than dropping the coroplast. to change it.

There are many discussions about sticking gate valves. A recent one includes my perspective on a key point of friction that cannot be lubricated by way of the pull cable or putting lubricant in the tank. See post #9 in this thread. https://gdrvowners.com/forum/operati...-lines-315rlts

I have a 2022 Imagine and the black tank valve handle is bent, always hard to operate from day one. The aluminum rod that the handle is attached to is bent and no amount of “ love” will get it to slide through the sleeve. I am on the tip of Baja so parts are hard to come by. Any help would be appreciated.

Thanks

Welcome to the forum! I can't offer you much help, if the rod is bent I'd be looking at replacing the cable and handle assembly, but of parts are an issue that could be tricky. To get you by for now, you might have better look finding a twist on valve to put right on your sewer outlet.

Also it's generally not a good idea to use an email address for a forum name,a lot of bots scour the site and could give you some spam. We (the moderators) can change your name for you just pm me and let me know what you want it to be.
