Having a water tank on an RV is pretty handy. You can take a shower, cook your dishes, and even wash your face while traveling. But things can turn upside down if the grey water tank starts to overflow.

What to do to prevent a massive catastrophe when you see an RV grey water tank overflow?

Well, to know what to do in this situation, stick around with us. That’s because we’ll show you the solution one step at a time. 

So, are you ready to start?

What to do when you see an RV grey water tank overflow?

The RV water tank can overflow at times. And it’s quite helpful to know what to do in these situations. Because you never know when you might have to tackle a whole tank of water.

For your convenience, we kept the process pretty straight forward. So, join us as we start explaining the process.

Step 1- Let the black water out of the tank

Firstly, you’ll have to remove the black water. What is black water? Well, it’s the water used to flush the toilet. Yes, the nasty and dirty water.

You see, if the black water flows out the hose first, then the greywater can follow its trail and clean the water hose a bit. That’s if you use the same hose for both black and greywater. In our process, we’ll use two different hoses to keep things clean.

Before starting the process, make sure to wear a glove first. As for the task, you have to connect one end of a hose to the city water connection. And the other end goes into the dump station.

Then turn the black water valve. This will let out all the black water from the tank. Once that’s done, you can move on to the greywater.

Step 2- Fasten the sewer hose

After you finish emptying the black water, you need to remove a cap. This cap is responsible for holding the tank outlets. Then you have to connect the sewer hose to the tank outlet.

The other end goes into the dump hole. Make sure it’s at least ¾ inches into the hole. Otherwise, water will splash out. And for extra safety, you can also cover the sewer hose.

For this simply put a brick on the hose. It’ll keep it in its place.

Step 3- Test the sewer connection

Next up you need to test to see if the sewer connection is alright or not. This way you can make sure that water doesn’t splash on your dress when you fully turn the valve.

So, all you have to do is gently turn the grey valve. One the valve is open it’ll allow some water to pass through the hose. And while the water passes, you need to see if there is any leak or not.

If you do see a leak, do take out the hose and fasten it again. This time make sure it’s tight.

Step 4- Flush and drain the tank

Once you’re entirely sure that there is no leakage, you need to open the valve fully. And yes, you have to open the grey one.

This will drain out all the water from the tank. And while you’re at it you can also clean the tank.

For this, you have to flush the tank again and again. Flushing remove all the waste from the tank. And you’ll get clean water every time you use the sink.

Step 5- Close the valves

Next up, you need to close the valve. Remember to do this before taking out the hose. Or else your face will get spattered by water.

Once you ultimately turn off the valve, you can disconnect the hose. But be careful while taking out the hose. Too much pressure can permanently damage the hose.

Step 6- Take the sewer hose out of the dump hole

Although the sewer hose is out of the tank, the other end is still inside the dump hole. So, don’t forget about that.

Be sure to take it out of the dump hole. But while doing so be very careful. That’s because some of the dirty water might still be in it. So, take it off slowly and make sure to wiggle it a bit.

The gentle shake will let out all the water, and you’ll be all set.

Step 7- Rinse the hose

For this step, you have to clean up the hose. Although the greywater might seem fresh it can still carry some dirt.

And you don’t want your hose to stay dirty, do you? So, plug it into a clean water supply. Then turn on the tap and let the clean water flow. This will take out all the dirt.

This way won’t have to worry about the hose staying dirty.

Step 8- Close the hole

Lastly, you need to close the hole in the water tank. Now, this is very important. Do not forget about it. We repeat, do not forget about the water tank hole.

If you forget to close the hole, the water will keep dripping out of your tank. Or even go to other parts of the RV and mess things up. So, be extra sure about the tank hole.

And once you do that, you will resolve the problematic overflow issue.

To sum up

Yes, that’s all you have to do when you see the RV grey water tank overflow. Remember draining the water might empty the water tank, but it’s better than having to deal with a flood of water.

Anyway, keep your water tank 3/4th full, and you’ll be good to go. So, that’s all for now. Take care of yourself, people. Adios!
