Help! I Have a Stuck RV Black Tank Valve
Don’t freak out. It’s completely normal for this to happen. Whether you’re a newbie or seasoned RVer, with all of the gunk and grime in your RV black tank, you might have to deal with a stuck valve at some point. It’s a relatively easy process that requires few tools.
Keep In Mind: RVing isn’t always the easy, carefree lifestyle some make it out to be, and we think it’s about time you knew these RV secrets.
How to Unstick Your Stuck RV Black Tank Valve
One way to unstick your RV black tank valve is to put Dawn dish soap and water in your black tank and then drive around. The sloshing around of the liquid will not only clean the inside of your tank, but it can get down into the valve and loosen whatever residue is there.
You can also try tapping on your RV black tank valve with a hammer. Make sure to do this lightly. If you break the valve, you’ll have more work to do and more money to spend replacing it.
Preventing Your Black Tank Valve From Getting Stuck Again
The biggest way to prevent a sticky black tank valve is proper maintenance. You’ll want to keep the rod well lubricated. Every so often, when you dump your black tank, spray lubricant containing silicon on the rod while it’s open.
After emptying your tank, work the valve open and closed a few times and then close it. If this valve breaks, it will be much more difficult to open your RV black tank valve, so do what you can to prevent this from happening.
How to Lubricate RV Tank Gate Valves
The process of lubricating the valve is simple. Buy a tube of lubricant that contains silicon from any big box store or Amazon. Do not use WD-40. This spray is sticky and could cause issues with your seals down the road. Use a product like Dow Corning 111.
As mentioned above, you can simply spray or rub the lubricant on the valve after you’ve dumped the black tank contents. Or you can take off the valve and replace it with a new one. This is easy and fairly cheap and could be the best option. If your valve is getting stuck, you might need to replace it down the road anyway.
If you want to take it a step further, you can remove your RV black tank valve and do a thorough cleaning. Make sure your tanks are empty and clean. Remove the valve from the flanges. Open the valve and soak it in hot, soapy water. Work the valve a few times in the water to ensure all of the residue gets cleaned out.
You can also inspect the seals during this process to make sure they are still in good condition. It’s safe to grease the seals as well when you position the valve back on the flanges.

How to Replace an RV Black Tank Valve
The first thing you need to do is make sure your black tank is empty and clean. Remove the bolts securing the valve. You may want to place a bucket underneath to catch anything that might leak out. Once you detach the valve, clean around the seals and gaskets. Before you insert the new black tank valve, you can lubricate the seal for preventative maintenance.
Once you insert the new valve, replace the bolts. Make sure not to tighten the bolts too much, or you risk cracking the flanges. Open and shut the valve to make sure it works smoothly. You can go ahead and add a lubricant. That’s all.
