Common Wall Hung Toilet Problems & Their Solutions

There are 3 common problems that occur in a hung toilet. We have them listed down below along with their solutions. 

Let’s get to it.

Problem 1 of 3: Toilet Feels Loose From The Wall

Oftentimes, you might feel your wall hung toilet is off when you sit on it. It might feel loose or jiggly.

This might happen due to the toilet not being installed properly in the first place.  But once you detect this problem you have to fix it sooner rather than later. Or it might lead to numerous other issues.

The toilet already contains a lot of bacteria. If this problem continues, the water might leak, spreading harmful germs.

Solution

To fix this problem, you’ll have to reinstall your toilet again.

Now, you can do it yourself if you think you have the skills. With the assistance of a helping hand, you can install it smoothly.

If you’re unsure about installing it yourself, you can always call a plumber. But first, verify if the plumber is qualified and licensed. This will provide you with the assurance that it’ll be installed right this time. 

Problem 2 of 3:  Constant Water Running After You Flush

If you hear that the water is running constantly, then it’s a major problem. Firstly because you’ll be wasting a ton of water. Secondly, because it’ll affect the flush of your toilet. As it’ll not be able to store enough water for flushing.

Here you just have to make some simple adjustments to the ballcock and float. Or replace it to resolve the issue. Trust me this is worse than your toilet flushing every now and then!

Solution 

For this, you’ll have to start by removing the tank cover. Take a screwdriver and adjust the ballcock and float. Then twist them to loosen them up. And adjust the height until you see that the constant water flowing stops. Then twist it again to tighten it!

If the adjustment doesn’t fix your problem, you have to remove and replace the float and ballcock! You can purchase these two from any hardware store.

Problem 3 of 3: Water Leaking Into The Wall

Sometimes you’ll notice that the water leaks into the wall when you flush. This usually happens because of poor plumbing connectivity or internal leaks.

You better act fast now! Because if you don’t, the water might leak into the wall and damage it. Hurry up before it reaches the wall through the waterproofing membrane!

Solution

Start by turning off the toilet’s water supply. This solution has a few options you’ll have to try from. After each solution, turn the water back on and check if there’s a leak!

The toilet bowl might be loosened. So, start by tightening the bolts of the toilet bowl. Securing this will turn off the water leak. If this doesn’t solve your problem, move onto the next one.

Check for cracks using color drops in the toilet. Just drop a couple of drops in the tank. And the color will collect on the cracks.  In such an instance, you have to replace the entire toilet.

Secondly, you can check for a loose connection in the water supply line. Therefore, tighten the line with a wrench and it’ll stop the leak.

Next, you can check the braided hose section. See if you notice any cracks. If you do, then remove the water supply line and replace it. 

If the leak is still there, the wax seal under the toilet might be damaged. So, take off the bolt connecting the toilet bowl to the wall. You’ll need someone to help you with the process to prevent any damages. 

After that, take your bowl and flip it over.  Scrap the old wax ring from the drain with a putty knife. Then take the new wax ring and place it over the opening of the drain. Now, flip your bowl again and reinstall it with the bolts.

It might also create problems with the water regulator. This is due to the overuse of water.

That’ll be all from us. Now, try out these fixes to solve your problem.
