How To Fix Water Backed Up In RV Shower
Tip #1: Check The Flow Of The Water
The best place to start with an RV is to look at the flow of the water in the tub.
You will want to see how much water is filling the tub and what is impacting it. For example, is water starting to pour out from other areas?
Is it coming straight out of the drain?
These are the details that will matter as they will allow you to pinpoint whether or not the issue has to do with the tub or the faucet.
In general, if the water is coming straight out of the drain, this means it is a full grey water tank in the RV. This is common and it does happen as time goes on.
Tip #2: Inspect The Grey Water Tank
The next step is to go to the grey water tank.
You will have to access this from the outside of the RV and it is going to provide instant access to a few connectors in the RV.
For example, you might have a situation where the black water tank has to be worked on. This is for the toilet.
You might have to dump water here too.
It is all about where the water is overflowing from.
In this case, the goal is going to be to make sure the grey water tank is clean. This is going to be done by accessing the grey water tank and then flushing it.
Pulling on the release is going to let you dump the water from the RV.
Tip #3: Dump The Grey Water Tank
You will want to dump the grey water tank.
The premise is to make sure you are taking the time to look at the seal around the grey water tank. When it is full, you will know it right away.
It will become obvious as you start to notice how much water is in the tank. It will begin to slowly leak out from the sides.
This is a clear sign that you will need to dump water from the RV’s grey water tank as soon as possible or it will continue to cause issues.

Tip #4: Recheck The Shower
You will now want to take the time to check the RV’s shower.
The idea is to see whether or not water is still overflowing from the RV’s drain. This will let you figure out what is wrong with the leaking fixture.
If the water is not coming out of the drain then you are good to go.
You will want to recheck the shower and make sure it is in good working condition.
This is just as important as any other step because you will want to be careful about what you are doing.
Final Thoughts
These tips will make it easier for you to manage the water backed up in the RV shower.
If water has backed up in the RV shower, you will want to empty the grey water tank. Start by checking where the water is coming from, access the grey water tank, pull to release the water, and then recheck the shower.
This is going to work and will ensure the RV is in good condition again.
During this process, it is also good to look at the RV battery, RV air conditioner, and RV toilet to see what can be done to make sure things are safe.
This is going to let you pinpoint what needs to be done to make sure the RV is working as it is supposed to and does not break down.
