Why Is My Toilet Not Flushing? and How to Fix It?

June 21, 2022

Why is my toilet not flushing properly? I’m not going to explain how gross it is to come across a half flushed toilet, but I definitely will provide you with some helpful solutions if you are suffering from this annoying issue. I did my own analysis of why my toilet is not flushing and would like to share the remedies I found. There are several contributing factors for toilet not flushing all the way, as well as solutions. 

Common Issues Faced By Toilet Users

There can be various toilet flush problems associated, and I have summoned up some of the frequent problems below.

The Toilet Flushes, But Waste Comes Back

This situation usually occurs when there is a blockage in the drain piping. A normal flush should send the water and waste down. But if something is blocking the way of compressed air and bolus of water, the pressurized air tends to send the waste back to the toilet.

Toilet Tank Not Filling With Water At All

If you are struggling with a toilet tank that is not filling up, the issue is mostly with the float. This happens when the float is too low, which acts as a barrier to water coming to the tank. You can check this by removing the cover of the tank.

The Toilet Flushes Slow and Weak

When a Toilet has weak flushing problems, there are two main factors you have to check. The first one is to determine the water level of the tank. If the tank doesn’t have adequate water in it, the toilet won’t flush properly. The second one is clogged in the toilet or pipe. I will provide you Weak toilet flush fixes later in the article, including how to Increase toilet flush power.

The Toilet Leaves Paper after Flush

This is because the toilet tank empty or there is no adequate water to flush the wastes strong. Again this is a symptom of a slow, weak flushing toilet, and water might be the culprit if the paper remains in the bowl. 

The Toilet Swirls But Won’t Flush

Poorly designed drain pipes, too much slack in the lift chain, or inadequate water levels in the tank are the three possible causes for this situation. Before you worry about low flush toilet problems, it is always wise to have a look at the water supply to the tank and its float. 

The Toilet Tank Not Filling But Water Running

As you read in the previous issues, if a toilet is not flushing strong enough, water in the tank is the first thing that you need to check, and it applies to this occurrence as well. The float must not be too high or too low in order to facilitate a smooth water flow to the tank.

Why Is My Toilet Not Flushing, And How To Fix It?

One thing that always concerns me about low flush toilet problems is that engineers are still unable to find a proper solution even though we live in the 21st century. However, before you seek the help of a professional, there are several investigations and implementations you can do on your own. 

Although there are various designs and styles of toilets, these problems often can be rectified without much effort. Here I have mentioned a home remedy for slow draining toilet.


One main reason for toilet water not going down is clogs. The first thing I have to warn you has never put anything that is inappropriate for toilets. Clogs tend to develop over time if you attempt to flush anything other than what they are made for.

Feminine products, paper towels, and diaper liners are some of the common stuff that most people flush in a toilet. In fact, some of the so-called “high-quality” toilet papers too can be problematic because of the strength of the made.

A clogged toilet is not difficult to identify. As we know, the water should go down within seconds along with the wastes if the toilet is functioning well. If the toilet is not flushing water rising, that is an indication of a clogged toilet.

 In addition, if the water levels go down slowly, it says your toilet is partially clogged, and if not cured ASAP, you could face more problems. However, before it becomes too late, you can execute the following to unclog the toilet without much of a problem.

Toilet plunger: Using a toilet plunger is one of the easiest methods you can try to unclog a toilet. All you have to do is put it in the toilet and tilt a bit to send water inside the cup to produce suction. When you are plunging, make sure you use short and fast strokes. This will ensure no air is entered into the cup to prevent the suction. 

Toilet auger: This tool is more or less similar to a snake. You can insert a toilet auger into the toilet and shake well to get rid of the clogs. Most of the toilet augers are made to prevent any damages to the toilet and pipes, so handling an auger won’t be difficult and does not demand expert knowledge.

Warm water: Yeah, I have used this method previously with a high success rate. For those who don’t have a plunger or auger, using warm water perhaps be the most convenient. You will have to use about a gallon of warm water for this; I have added some liquid dish detergent to get lubrication to help the clogs to slip down the pipe.

You must pour the water fast into the toilet to get the best results and if you don’t see immediate improvement, repeat the process twice after about 20-minute intervals. 

Check the Flapper

Flapper checking is critical part of my route course analysis of “why is my toilet not flushing?” The flapper is the rubber part that gets attached to one side of the water tank’s lever chain. When you depress the lever, the flapper helps water drop down to the toilet bowl. However, a loose connection of the flapper with the chain can halt the fast drop of water. 

In addition, these flappers can degrade over time to cause toilet water not going down. So, if you notice any malfunctions on the flapper, you should buy a new one and replace it.

The Water Level of the Toilet Tank

To perform a successful flush, your toilet tank should release at least 80% of its full capacity. When water is not filling up the tank properly, there is no chance of releasing adequate water to the toilet bowl. So before you think about solutions for how to fix a toilet that won’t flush, the first thing you have to verify is whether there is water in the tank to get the job done. 

Ensure the tank’s water supply is not turned off, and turn the valve to the highest allowed level if the tank is not filling up fast. Check on all the parts of the water tank to see whether there are any faults. If something terrible happened, you must get the help of a professional plumber rather than worsening the situation by trying stuff on your own.

Check the Rim Holes

This might not be the case with most, but I must tell you that there is a possibility of rim holes getting clogged due to high concentrations of calcium and such minerals in the water you use. These deposits can be a barrier to smooth water flow from the tank to the bowl and eventually slow down the speed of the flush.

In order to remove such clogs, you can use a wire in each hole, and for better results, I use toilet cleaners that are specifically designed to remove mineral deposits.

How to Improve Toilet Flush Performance?

After you remove the clogs or don’t want to face issues with your toilet, it is always crucial to maintain it in a proper manner to get a high level of flush performance. It saves you money and definitely keeps you away from annoying situations. Here are my secrets.

  • Inspect the float of the tank and the water level when possible. As you know by now, poor water flow is the main reason for a clogged toilet. 
  • Don’t flush unnecessary things even though you feel they will not get clogged in the pipe. 
  • Clean the flush holes (rim holes) if you happen to use mineral-rich water in the tank. It will be ideal if you check these holes at least once a month.
  • Use bleach to clean the toilet bowl. Yes, the ambition of this is not just to clean the bowl but to clear the blockages as well. You can use a gallon of bleach as the cleaner and let it be there at least for 20 minutes before you flush. My suggestion would be to empty the water tank and turn off the water supply to the tank before putting bleach into the bowl. This will prevent accidental flushes and keep bleach for the required time. 

My Recommendation

Ok, guys, I think now you can help yourself answer why is my toilet not flushing. However, I have a better recommendation for you to keep this issue at bay. That is to use a dual flushing toilet if possible. These types of toilets tend to flush the wastes way more efficiently compared to ordinary toilets, and you will be amazed to hear that these toilets use less amount of water as well. 

Dual flushing toilets utilize a bigger diameter trap way that is better than conventional toilets in terms of clogging problems. In addition, you don’t have to use water unnecessarily to flush away the liquid wastes, which is pretty helpful to conserve water.

In addition, you have total control of the flushing process, and you can determine the amount of water you need to flush according to the requirement of wastes. 

The only downside of these toilets is that they are a little bit expensive. Also, you would want to keep a toilet brush near the toilet as sometimes the flushes you create might not provide sufficient power to get rid of wastes properly. However, one thing I can assure you is that you don’t have to keep a plunger!


My toilet won’t flush, and it’s not clogged, why is my toilet not flushing? toilet won’t flush no water in tank these are the queries that I thought to answer in this article. Moreover, you can opt for a dual flushing toilet to minimize the toilet clogging issues as well. I’m not a professional plumber, but these are my prior experiences, and I’m inviting you to add your suggestions as a comment. Have a great day!
