    Holding Tank Valves are hard to pull. Ideas?

    I have a 2016 Bighorn 3270rs. The holding tank valves in the universal docking system are extremely hard to pull out and push in. I sprayed both silicone and WD40 by the pull-outs, but that did not seem to help. Any suggestions on how to make the valves easier to maneuver?

    Re: Universal Docking System Holding Tank Valves

    I've had some success with 2 approaches: 1) vegetable oil and dawn liquid dish soap down the drain into the tank, and lubricant spray into the sewer outlet. Let sit for a few minutes and then exercise the valve by opening and closing a few times. 2) spray lube on the valve plungers. You'll need to either drop the corner of the front section of coroplast or create access openings.

    I've installed zippered trap flaps in the coroplast to allow access to the valves. You can also get them from Amazon at a bit higher price.

    My experience is that it's not the cables, but rather the valves. Possibly have TP stuck in them. Have had nothing but problems with our remote cables and valves over the last 4 years. I looked into electric valves, but reviews indicate they have the same issues. IMHO it's a terrible design. Hope you have better success than we have had.

    We have the same rig though 2017. Our grey #2 was very difficult to close and sometimes leaked past the valve. My second attempt to rectify, which was successful, involved breaching the belly again, disconnecting the cable end from the valve, re-routing and removing 30. Two fingers now open and close that valve
    Grey #1 will need addressed the same at some point
    Black tank valve has always worked smoothly

    Having same issue with mine for several years. Just been muscling it. Need to figure out how to strategically go about shorting the cables and lubricating the valves.

    Second the baby oil or vegetable oil down the toilet or sink to lube the valve. That solution was posted on an RV maintenance video I saw awhile back. The oil also helps lube the toilet flush plate rubber.

    Plumbers grease wiped on this seal does a great job. Plumbers grease in a small tube can be found at any big box store and many good hardware stores.

    Re: Universal Docking System Holding Tank Valves

    May I suggest to shorten the cables and add a lubircant to the neck at the base of the valve stem to each valve. I use one that is non toxic that can be used on faucets and filter gaskets as well. And do put the Flex Mend trap in for each valve. If you don't you will be sorry you did not. Over time, depending on use, the valves do have to be replaced.

    Do not use WD40 from the UDC. It will clean the existing lubricant off the cable.
