What Is Rear Discharge Toilet Problems?

The rear discharge problem means it caused by the backside of the toilet. The toilet is connected to the backside wall of the bathroom. On the other hand, the rear discharge problem affected the flushing system and also drained the waste properly.

However, let’s find out the problem first and solve them step-by-step without spending much time. So, let’s get started.

Clogged Toilet

This is one of the major problems I have ever had. This problem originated from several sources. For example, rust, uncleaned, plunger, and others. This problem is not only caused for your toilet discharge but also creates flush and other problems.


Using household elements or chemicals, you can clean or remove a clog from your toilet. However, you will use baking soda and vinegar to fix the problem. In a pot, mix these two elements properly and apply them to the affected area.

After 15 to 20 minutes, you can clean the toilet and flush it. You can use an automatic cleaner tablet if the problem still comes out. You can easily find this type of tablet to remove clogged from your toilet from online and offline shops.

Loose Toilet Handle

In some cases, the toilet handle may be loose, and this problem comes out. Two things actually cause this. First, the toilet chain may detach, which you need to reattach. Secondly, the nuts of the toilet become loose, which you also need to fix to solve the problem.

Wrong Rough-in Size

When you incorrectly measure the rough-in size for your toilet, you face a rear discharge problem. A plumber needs to measure the rough in the right way. However, the standard rough-in size is 12 inches.

It would be better for you to measure the rough-in manually. You may find the size from 10 inches to 14 inches without getting any problems.

Back to Back Toilet Problems

Most of the time, the back-to-back problem is a common problem in our toilet. This problem comes out because of several reasons. First of all, your plumber wrong installed the rough-in. It is essential for a person to apply the right measurement toilet rough-in.

Secondly, the clogged problem also causes this problem. Clog not only created back-to-back problems but also brought the water above and avoided smooth flushing.

Overall, these problems are common problems. Check out the drain line of your bathroom because sometimes the drain pipe is damaged and needs to be replaced.

Rear Discharge Toilet Seal

A rear discharge toilet seal is an essential thing to avoid leakage from the toilet and save water. When you are going to assemble a toilet in your bathroom, you have to use a toilet seat for the ideal installation. Though the plumber used a seal to assemble the toilet, you should check it out to get a clear concept.

On the other hand, seals also avoid maximum rear discharge problems. Ensure that your plumber uses a high-quality rear discharge toilet seat that strongly protects your toilet.

You will get plenty of advantages from your rear discharge toilet when you use the quality seal. To get clarification, you should recheck that your plumber used a quality seal in your toilet.
