I've never "lubed" my waste tank valves?? Didn't know that was an option? Going on some 16 years with the same trailer and the valves seal just fine over all those years..

I did have some TP get stuck in the black tank valve so had to remove, clear the TP and reinstall, but that was some 5-6 years ago and no problem since..

How would you "lube" them in the first place??

Not trying to be an Ass... Just have never heard of that before and have never done it before and have never knew there was a need to do it??

Since I now know it’s an issue...40 years after my first TC...I’ll lube them religiously.

Dump the tanks, close the dump valves, dump in a quart of vegetable oil, open and close the dump valves rapidly a few times to spread it around.

NEVER USE ANY KIND OF PETROLEUM PRODUCT LIKE VASELINE OR 3-IN-1 OIL!

I would think that any oil would float on the black water and not do much lubricating. I would think one would need a water soluble oil if such a thing exist. Maybe the oil that is used to cool cutting tools in a machine shop.


Please give me enough troubles, uncertainty, problems, obstacles and STRESS so that I do not become arrogant, proud, and smug in my own abilities, and enough blessings and good times that I realize that someone else is in charge of my life.

When I could actually get to the valve, a couple of shots of vegi oil did a great job.
