Valve sticks, really hard to move either direction. Have tried the lubrication recommended by RV store, not much improvement. Any ideas, I am afraid the pull handle will break.
Thanks,

Some of the treatments for the black water tank claim to lubricate the valves. Might try one with a gallon or two of water.

very inexpensive to replace the valve. I would think that would be your best solution.

Agree with the valve replacement. Inexpensive, and you still haven't broken the old one. If you pull the handle out of the old one, it's going to get a lot worse, really fast.

From my "been there done that" file.....just take 10 or 15 minutes and replace it.

IMO try this first. Get a spray can of silicon lube. EMPTY tanks. Now fog at least a third of the can up the pipe while opening and closing valve. Spray a bit on the handle shaft also. It works GREAT for us. Storing tanks with peanut oil also helps lube valves. We use peanut oil as it is cheaper than coconut oil sold by camping stores to lube valves.

Sticky dump valves can be fixed by opening the valve, drilling a small enough hole on the flat side of the valve. Screw in a grease zerk then close the valve. Shoot some grease in and work the valve back and forth as it will spread the grease and in a short time the valve will operate smoothly....when it starts working stiff again...shoot some more grease.

Sounds like its time for a valve replacement. Very easy and inexpensive. Do it while the current one still works and you can drain the tank Why risk having it break and stick closed when you have a full tank?

Before you do all of the hard work try spraying the rod when the valve is open with a good penetrating lube. Worked on mine and a lot easier than replacing.

If you replace it I recommend Valterra valves. The cable can be shortened to provide the most efficient connection. My Bristol valves have a 6 ft. cable no matter how it is routed.
