Unfortunately, this does not mean it will always work as you want it to.

You could have a situation where the Dometic RV toilet won’t hold water.

If the Dometic RV toilet won’t hold water, this means the seal is damaged, turn the water valve to “Off”, pour toilet cleaner into the toilet, wait a few minutes, and then re-test the toilet.

It is possible you could have a much bigger issue on your hands.

This includes a situation where the unit has not been installed properly and/or it is not in the right position. This creates a situation where the seal is inefficient and it does not work the way you want it to.

This guide is going to showcase how to fix a Dometic RV toilet that won’t hold water and what to do about it.

How To Fix Dometic RV Toilet That Won’t Hold Water

Tip #1: Wipe The Seal

The first step is to take a look at the seal.

Sometimes, the seal is going to be damaged and/or loose, which means water is not going to hold in the Dometic RV toilet.

This is common because the seal has to be robust.

If it has not been installed the right way, this could be the number one reason for the Dometic RV toilet not holding water as it should.

In a situation such as this, the best bet is to take a wipe and then use this to run over the seal. You will want to get rid of any debris to see whether or not the seal is intact.

If the seal is not intact, this is what you are going to have to fix.

Water is going to continue to leak until you take the time to do this. You will want to be diligent and use the right solution to fix the seal.

Tip #2: Turn Toilet Water Valve To Off

Let’s assume the seal is fine with the RV toilet.

What are you going to do then?

You are going to want to start by turning off the toilet water valve to the “Off” position. This is how you are going to get the valve to settle into place and it is going to allow you to get a better look at what is going on with the fixture.

For example, you can then begin to work on potential clogging that is creating issues in the fixture.

Once the water valve has been turned off, you are now going to begin to work on the clogging.

Tip #3: Pour Toilet Cleaner Into The Toilet

Your best solution is to get a good toilet cleaner for the Dometic RV toilet.

The goal here is to see whether or not there is a clogged part in the toilet. You are going to want to use a little bit of toilet cleaner and pour it into the toilet.

This is going to help take a look at what is going on with the fixture.

Look to pour it into the toilet and then see what is wrong with it. After you wait a few minutes, the toilet is going to be unclogged.

Look into all relevant details when managing key fixtures in an RV.

Tip #4: Re-Test The Toilet

The last step in the repair process is going to be to re-test the toilet.

This includes turning the water valve back on and seeing whether or not the water is leaking. If it is not holding water, you will know there is still an issue with the fixture and it might have to be reinstalled.

This is a common issue with newly installed toilets in RVs.

You will want to be quick to make sure the results are efficient and you are not left in a spot where the RV toilet does not work at all.

Take the time to test it thoroughly when you are in a situation such as this one. This will make sure the RV is in good shape.
