Help! Black Lever Stuck

[Sneakyp]

We can’t close our back tank. Reads 2/3 full and it is empty. We were driving on very rough roads. Tried flushing it out and lubing up lever. Still can’t close it and am out camping. Any suggestions?

Do you mean it is stuck in the "up" position? My rig has lived its entire life in the desert and my drains tubes were very sticky and hard to open the first time I tried. Sprayed them with silicone and then gently rocked them back and forth while in the open position, which worked to allow the silicone spray to penetrate. Let it sit for an hour and was then able to open and close them and it became easier the more I did it. My manual even states that they will be hard to open until water is flowing through them to lubricate the seals.

It’s the black tank handle that you pull to open tank and push to close it. We have siliconed it and flushed out the tank completely. The handle will not go in. So now we can’t use toilet as valve is stuck in open position. We have tried wiggling it for hours now. So difficult to deal with when out camping.

The good news is the tank is empty. The gauges are notoriously wrong due to dirty sensors, etc. Replacing the tank valve isn't a difficult job. It's also possible that something is stuck in the valve. Here are a couple of links that may help:

Mine has hose clamp that attaches the valve to the drain pipe. You can see the metal band in this pic. They are made to be replaceable. I assume yours is the same. Maybe removing the whole valve will make it easier to work on getting it closed.

Rubber gloves and (I think) an 8mm box end wrench will loosen the 4 retaining nuts. As you loosen them all, try the knife valve. If it is still frozen, remove the whole shebang, and clean, then spray with PAM or similar silicone product.

Usually hear this same scenario when someone has used WD40, on the dump valves . Causes the seals to pop out of slot a bit and get caught in the slide travel . Mechanism.
