    Re: Universal Docking System Holding Tank Valves

    Yes. I think this was discussed before in a thread on a different topic but WD40 is not a lubricant in spite of what many think and it hardens after some time. Many of us using it on guns years ago found out that it turns to varnish after awhile. There are some in-depth write-ups on that subject.

Over time, depending on use, the valves do have to be replaced.

    Re: Universal Docking System Holding Tank Valves

    On both my 2010 Bighorn and now my 2017 Bighorn I had to have the cable on my black tank changed from 10 foot to 6 foot in length. Now works with one finger. My repair guy wonders why Heartland doesn't learn. He has changed too many to count.

    Just an FYI for the next time or whomever, the cables can be shortened just as easily and cheaper especially if you’re a DIY guy

    Re: Holding Tank Valves are hard to pull. Ideas?

    While I think the main cause of black tank valve hard operation for me is problems with the valve and seal itself, I can remember years ago when I rode a motorcycle and the cable controls got really stiff. I found a molybdenum cable spray kit at the motorcycle shop that used the spray tube and a foam seal to shoot the moly lube down the cable/casing. The improvement then was immediate and dramatic.

    I agree that is may not be the cable but the actual plunger. You can access this from the bottom and will notice how it works, just put some lube on that plunger and that may?? solve your issue.

    Replaced my gray water valves twice after two years, and last February, replaced the black tank valve. The black tank valve finally starting to leak after four and a half years. The seals were warn and the bottom of the edge of the valve was not smooth anymore. You have to be careful installing the valve not to unseat the rubber seals. That is the reason I had to redo the gray water valves after three months. The edge of the valve caught the top of the seal and deformed them.
