Wall Mounted Toilets Problems and How to Fix Them?

Wall mounted toilets are among newer solutions for a modern bathroom. However, as they haven’t been on the market for too long, not many people know how to deal with the wall mounted toilets problems.

Accessing the tank of wall mounted toilets can be a problem. This is why not even some plumbers want to agree on fixing them. Fortunately, with our guide, you’ll learn how to deal with some basic issues on your own.

What Are Wall Mounted Toilets?


Before we start talking about wall mounted toilet problems, it’s important to briefly explain what these toilets are. You probably know how regular toilets look like. You might have even heard about macerating toilets. But do you know what wall mounted toilets are?

Wall mounted toilets are fairly new addition in the history of the toilets. [1]They are designed to take up less space than regular toilets because their tank is inside the wall. Most of the time, it isn’t possible to convert floor toilet to wall mount. These are units specially designed to partly fit into your wall.

This type of toilet can help you save space. They are amazing for small toilets – in fact, they can save up to 10 inches of space if the tank is entirely moved into the wall! Most of the time, you can also adjust the height of the bowl. This makes them rather versatile.

Proper wall mounted toilet installation is mandatory in order for this unit to be working properly. This is why it’s important to find a professional who knows how to complete wall mounted toilet plumbing the right way. If you don’t, you’ll have many issues with your toilet later on.

Common Wall Mounted Toilets Problems


Overall, there are three wall mounted toiled problems that commonly happen. These are:

  • Toilet becoming loose from the wall
  • Water running after flushing
  • Water leaking into the wall

Fortunately, most of them can be solved if you know a couple of tips and tricks. Here’s what we mean by that:

1. Toilet Loosening from the Wall

You probably know what we mean. How many times did you sit on the toilet just to feel it being jiggly? When this happens to a wall mounted toilet, things get even more scary. No one wants to feel wall hung toilet movements.

Most of the time, the reason behind this is improper installation that we’ve already talked about. But once this problem starts appearing, it is better to fix it as soon as possible. Otherwise, you’re in for a lot of issues, such as:

  • Toilet breaking
  • Water leaks
  • Bacteria infestation

Unfortunately, the only way to fix this wall mounted toilets problem is to install it once again. If you have the skill, you might be able to do it on your own, especially if you have a skillful friend who can provide a helping hand.

If you aren’t certain how to do this, you can always call a professional plumber. Just make sure to verify whether they are licensed and qualified to work with wall mounted toilets. Otherwise, you might end up paying him money, just to end up with an improperly installed toilet once again.

Another thing you need to be mindful of is the wall mounted toilet weight limit.[2] Wall mounted toilets sometimes cannot hold as much weight as regular toilets. If a person who is bigger than average plans on getting a wall mounted toilet, they need to make sure the limit is fitting for them.

2. Water Running after Flushing

When you flush, you want the water to run. Otherwise, the toilet would remain dirty. However, if the water keeps on running even after you’ve flushed, this isn’t how things are supposed to go.

There are many reasons why you don’t want to have water running from the tank even after you’ve flushed, including:

  • Waste of water [3]
  • Improper flush
  • Water damage
  • Black stains on the toilet seat

Fortunately, fixing this problem isn’t challenging. In fact, it’s almost exactly the same as fixing regular toilet seats. You should adjust the ballcock or float – or replace both of them, if the issue won’t go away.

To do this, you should remove the tank cover. This shouldn’t be challenging, even though the tank is located inside the wall. Then, take a screwdriver and loosen the float and the ballcock. Adjust the height of them until you notice the water can no longer get through them once they are closed. Twist everything once again and make it tight.

Sometimes, this isn’t enough to fix it. If no matter how much you’ve adjusted the float the water still keeps on running, chances are that these two items have worn out. You should go to a local hardware store and look for replacement parts.

To make things easier, remove the float and the ballcock from the toilet and take them to the store. This way, you can be certain you’ve gotten the parts that can fit your toilet.

3. Water Leaking into the Wall

If you notice water leaking into the wall when you flush, this is a problem you should deal with as soon as possible. Otherwise, you are risking severe problems, including even the structural damage to the property!

The solution to this type of wall mounted toilet problems is a bit more complicated than the other ones we’ve mentioned. There are many things that might’ve caused the water leaks, so you should be patient. Luckily, if you know what to look for, finding the cause isn’t that challenging – and then the solution will be near.

Here is what you should do:

  • Turn off the water supply to the toilet. After each of the following steps, turn the water supply back on and flush the toilet to see if the problem is fixed.
  • Make sure that the bowl on the toilet is properly hung. Sometimes, the issue can be because the toilet isn’t properly installed. Try to tighten the bolts and see if this makes the leak stop.
  • Check the toilet bowl for cracks. Just because there are no visible cracks, doesn’t mean there aren’t any. Using color drops is a good way to notice them. Unfortunately, if this is the cause, you’ll have to replace the entire toilet bowl. Don’t try using solutions such as epoxy for toilet tank repair – these won’t work on the ceramic bowl.
  • Look at the water supply line and see if there are any loose connections. If there are, tighten them with a wrench.
  • Look at the braided hose section for cracks. If you notice them, replace the water supply line.
  • Sometimes, the cause of the leak is damaged wax seal. If you suspect this is the issue, take off the bolt that connects the bowl to the wall and flip it over. Use a putty knife to remove the old wax ring and replace it with a new one. Reinstall the bowl.
  • If you’ve used the water too much, chances are you have a faulty water regulator.
