Why Toilet won’t flush Water Rises same time?

Sometimes the toilet won’t flush for many reasons, you know from here, but if the water rises at the same time, this may indicate different causes.

Cause1. Toilet won’t flush, but water rises not clogged Due to BLOCKED VENT PIPE. 

If your toilet bowl water rises when you flush, but the toilet itself will not flush, then you likely have a blocked vent pipe. This is a common problem in older homes, as the vent piping can become blocked with dirt and debris over time. 

The blockage will prevent the toilet from flushing properly and cause the bowl water to rise due to the lack of airflow.

You can do to try a few things to unblock the vent pipe yourself. 

First, try using a plunger to clear the blockage. If that does not function, you can try using a plumbing snake to clear the pipe.

Cause2. The toilet won’t flush water just rises due to CLOGGED IN S-TRAP. 

The toilet won’t flush – the water just rises due to a clogged S-trap.

A toilet with an S-trap has a hidden trap underneath the bowl that connects to the main drainage system. This type of trap is less common today, but they are still found in some homes. 

S-trap plays a critical role in safe and effective plumbing system operation. It can also be more prone to blockages.

The S-trap’s primary purpose is to prevent sewer gases from entering the home by creating a seal between the drain and the trap, also preventing odors from emanating from the drain.

Although, The S-trap can be more difficult to clean than other types of traps and due to its carving path, tissue, wipes, and other items are present there.

In this case, you must clear the clog before the toilet flushes properly again. 

You can use a plunger or a plumber’s snake to do this. After this, use baking soda or Epsom salt.

Another main reason for rising water in the toilet and not flushing is because of septic tank is full.

If your toilet bowl water rises when you flush, and you have determined that the problem is not a clogged S-trap or vent pipe, then it is likely that your septic tank is full.

A full septic tank will prevent the toilet from flushing properly and cause the bowl water to rise.

It is important to remember that a full septic tank can cause problems with your toilet and lead to back-ups and sewage spills and overflows. Therefore, it is important to address the problem as soon as possible.

Cause4. Toilet Won’t flush properly, but water rising due to CLOGGED DRAIN PIPE.

A toilet that will not flush properly may signify a clogged pipe. If the water rises in the bowl, the clog is likely in the main drain pipe. 

This can be a difficult problem to fix on your own and may require the services of a professional.

If you feel the clog is in the drainpipe, you can use a plunger to clear it.

Be sure to cover the overflow hole in the bowl with a cloth so that the plunger can create a good seal. Try to create suction by pushing and pulling the plunger up and down. If the clog is cleared, the water will drain from the bowl.
