Now we will tell you why your toilet bowl water level is dropping, and with that, we will tell you the fixing process. You have to identify the reason and step by step solving the problem;

1. Clogged Vent Water Level in Toilet Bowl Keeps Dropping

A clogged toilet vent decreases drain flow and can cause clogged water levels. Furthermore, the water creates a suction that can damage the pipes and empty P-traps, causing a sanitation issue.

This problem is typically caused by a buildup of waste, toilet paper, and non-flushable items in the main drain and sewer lines. Some pressure, such as tree roots or excess building weight, can cause the vent line to break.

Symptom

To determine the cause of this symptom, turn on all of the faucets and flush the toilet. You will hear gurgling and bubbling sounds when water flows down the drain, indicating that the vent is clogged with debris or something else.

Fixing

First, check the vent where the vent is open to pass the sewerage line and see any material such as debris or heavy particles. Then clear away the debris and other obstructions so that water can flow freely.

After that, pour some water from the upper side of the vent to clear completely. Sometimes for clogging heavy particles, you might need a drill to break them and remove them from the vent, and if you need to apply this auger process, you should arrange a minimum of 200 fit augers.

2. Cracked BowlCracked Bowl

Accidents happen, and sometimes they happen to you unknowingly, like this causing damage to your toilet that you may not be aware of. The majority of the toilet is made of porcelain, which can crack or break very easily. 

Simple repairs are also frequently the cause of a cracked toilet, and as a result of this crack, water can leak. As a result, the cracked toilet could be another cause of the low water level in the bowl. If you notice a crack on the toilet tank after identifying the problem, it should be repaired as soon as possible.

Symptoms

First of all, the bowl won’t stay full, but that can occur for other reasons. To fill the toilet bowl with water, after filling the toilet, turn off the faucets that the water can’t run outside. 

After doing this, wait for 1-2 hours, and if you notice that the water is less in the toilet bowl than before, even though it is turned off, then be sure that your toilet bowl is cracked.

Fixing

Remove the water from the bowl remaining flush and turn off the water supply. Secondly, unscrew the whole toilet and remove it from the toilet. But some people attach the toilet to the floor with cement. To replace the toilet from this condition, you need to break the toilet and cement coat; this work is pretty much tricky, and you may need to have a plumber for this.

After removing the toilet, installing the new toilet, and installing the toilet by screwing, install the toilet simply through screwing. But those who have no option to install the toilet by screwing can apply the new simple screwing way or attach the toilet with cement.

3. Damaged Fill TubeDamaged Fill Tube

A fill tube is a vertical tube located inside a toilet’s tank. Its purpose is to move water into the bowl if the ballcock fails, preventing the tank from overflowing. However, this fill can be damaged for various reasons, and if this occurs, the water will not drain or refill properly, resulting in a low water level in the bowl.

On the other hand, a damaged fill tube can cause water to leak from the fill tank, resulting in a constantly dropping water level in the toilet bowl.

Symptoms

When you bought a new toilet, your toilet fill tube could fill your toilet water tank much faster, but after facing this low water level issue, if you see that your toilet fill tube takes more time than before to fill the tank, be sure your toilet fill tube is damaged.

On the other hand, after filling the tank, if you notice that the tank has less water than before, then be sure that your toilet fill tube is damaged.

Fixing

Replace the damaged fill tube and install the new one is the only way to get this problem. First, flush the remaining water from the toilet tank, remove the damaged fill tube, install a new fill tube, and don’t forget to separate the float ball.

4. Leaky Flush ValveLeaky Flush Valve

When the lever on the toilet flapper/flush valve is pressed, water is released from the tank into the bowl. However, if the flapper/flush valve does not seat properly and forms a tight seal against the valve seat, water leaks from the tank into the bowl. Because of water leaks from the tank, you have a low water level in the toilet bowl. 

Symptoms

There is the clearest sign that a flush valve needs to be replaced and for this mix some food color into the toilet water tank. If you find coloring leaking water into the bowl after a minute without flushing, the flush valve and flapper are leaking.

Fixing

Replacement is only one way to solve this problem, and to do this work, flush the water from the toilet tank. Remove the damaged flush valve/flapper with a screwdriver and install a new one and check with the color mixing process of any water leak from the flush valve/flapper.
