Why does the toilet flush slowly?

There can be many reasons why a toilet flushes slowly or not enough. Some common causes could be as follows:

A low water level:

One of the main reasons toilets do not flush properly is that the tank does not have enough water. Because of less water in the tank, the toilet cannot flush to its full capacity. This reduces the pressure of the water. If the tank were full then there would be enough force to move everything into the toilet bowl into the drain. The low water might leave some of the waste and you will have to wait for the toilet tank to refill. An easy fix to this is changing the float level in the toilet tank. The toilet float is the topmost level where the water reaches. 


Some minerals like magnesium or calcium can accumulate near the jet holes when the water flows from the tank into the bowl. These build-ups can obstruct water flow. If these continue to build up, they can clog the force of the flush. These mineral build-ups are typical in areas where there is hard water. To ensure that these minerals don’t build up, you can do two things. First, you can install a water softener. Second, you can use white vinegar and bristle brush to clean the clog.

Clogged Drain:

Usually, you will be able to spot a clogged toilet. An easy solution to a clogged toilet is to use a plunger to help break the waste. However, if the toilet is partially blocked, it will be difficult for you to identify it. This is because the toilet will flush but not with full force. Even if you cannot diagnose this situation immediately, there are some methods to unclog the toilet. The first method is to use a plunger. The second method is to use a drain snake. 

A problematic valve:

Sometimes a slow flushing toilet is because of a faulty valve assembly. The valve is responsible for releasing the water from the tank. If the valve is not fixed correctly, then it affects all of its corresponding links, such as the chain, the lever, the flapper and the flush valve. The flapper is a simple ball that is responsible for blocking the opening of the toilet bowl. If there is a problem with any of these, the water flow will be restricted. You will have to open the valve and check it for any assembly problems to solve this. You can also replace the valve if the problem continues. 

Obstructed vent: 

The underlying problem with the water flow can be a plumbing drain line. These drain lines connect your home pipes to the municipal system. These lines are combined with vents that escape foul smells or gasses. If these vents are blocked, they can hamper the force of the flush. But, cleaning these vents is difficult for you to clean yourself. So, you might need to hire a plumber. 

How do you clear a slow draining toilet?

Some of the ways you can clear a slow draining toilet are as follows:

Replacing the fill tube

The fill tube is a black rubber tube that leads into a more extensive tube called the overflow tube. After prolonged use, the fill tube can get damaged and might come out. If this happens, the valve will automatically shut off. This will cut off the force of the water as it fills the bowl. You can replace the fill tube. If it has come out, then you can attach it back. We advise you to check your fill tube regularly. 

A crack in the toilet bowl

A crack in a toilet bowl is not typical, but it can happen over time. Most of the time, these cracks are not visible, but if you notice small puddles of water around the base of the toilets, this is a clear sign of a break. A temporary solution is to use a sealing agent like cement. However, this will not last long, and eventually, you have to replace the toilet bowl. 

Cleaning the vents

Sometimes, the vent may get blocked and stripped, providing fresh air into your drainage system. The clog is a result of debris stuck in the vent. To get rid of that, you need to get a plumber’s snake and clean the blockage. 

Drain cleaning

The best homemade method of cleaning a drain is to use dishwashing soap and hot water in equal quantities. To clean the drain thoroughly, pour several cups of soap into the drain. Let it be for some hours, and then wash it down with hot water. This will also help you to get rid of some calcium deposits. 

Will a Liquid plumber unclog a toilet?

Liquid plumber drain openers are not that effective when it comes to unclogging the toilet. These products are used in smaller areas and are more effective there—for instance, kitchen sinks or washbasins. When a toilet gets clogged, the volume is much more. Primary chemical-based products will not work as efficiently as mechanical products will. 

How to Prevent Clogged Toilets?

We have looked at the various reasons why your toilet could be clogged. Now let us see what we can do to prevent them from clogging in the first place.

  • Always flush twice.

Flushing the toilet twice is not necessarily an environment-friendly method, but it will prevent your toilet from clogging. In addition, Flushing twice ensures that any remaining waste in the toilet bowl is also flushed down.

  • Leave the toilet tanks alone.

Many people use their toilet tanks as extra storage space to hold their cleaners, soaps, etc. This puts unnecessary weight on the toilet tank. It could dent the surface. Furthermore, if you are not careful, you may knock some of these items into the toilet and cause a massive problem.

  • Be careful as to what you flush.

Toilet clogs’ root cause is waste items that do not come out of your body most of the time. Toilets are not dustbins, and you should remember that the next time you flush anything down the bowl. The extent of items you can flush down apart from your waste is a toilet or tissue paper. Be careful to avoid anything more, as it might jam in the tube and cause a clog.

  • Act instantly in case of a clog

If you feel like something is wrong with your toilet bowl or the flush, do not wait for the situation to resolve itself. More often than not, you will end up making it worse. Of course, before you panic and call the plumber, you should try the methods mentioned above yourself.

  • Clean the toilet bowl regularly

Even though this goes without saying, you must always clean your toilet regularly. You will spot leaks and cracks quicker if you have a regular cleaning habit. It will also help you in seeing where the leakage is coming from. This will help you get to the root cause of your leak faster. 

  • Get your toilets professionally checked.

We recommend getting your toilets checked by a professional plumber at least once a year. A professional will tell you when it is time to replace some parts or fix some aspects of your toilet. You must remember that replacing an entire toilet is much cheaper than replacing multiple parts over time. 

  • Do not use chemical toilet cleaners

Toilet cleaners are supposed to be safe to use on piping and the overall make of your toilet bowl. However, if you use harsh, chemical cleaners, it might damage your pipes.

Toilet Unclogger Liquid: Buyer Guide

We know that toilets can get clogged by hair pieces of paper or plastic. Even item or mineral deposits are common causes of a clogged toilet. There are a lot of liquid cleaners for your toilet. Many of them have different properties. Different types of cleaners have various purposes. For example, a cleaner used for a kitchen sink will not do anything to a clogged toilet. Understanding your requirements is essential when looking for a good toilet liquid cleaner.

For an extremely clogged drain, go for an acidic liquid cleaner if you need a cleaner. However, if you want a cleaner for everyday use in your house, then go for something that is non-acidic. 

Some things to look out for are as follows:

  • Consider the type of clog

Most clog cleaners are designed to work on specific types of clogs -for example, soap clogs, hair clogs, and mineral deposit clogs. Therefore, buying a good cleanser is simply finding the proper cleaner for your clog. Luckily, it is easy to find cleaners for toilets because most of us have a fair idea of the clogs we might expect. 

  • Look for the cleaner ingredients.

These days, there are eco-friendly, plant-based, cruelty-free, biodegradable, and even chemical-free cleaners. We assume that toilet clogs can only be dissolved by using the strongest chemicals possible. However, the stronger the chemical that you use, the more harmful it is to your health. Most acidic cleaners produce dangerous fumes, and you are warned against handling them without proper gear. Harsh chemicals do the job, but they are not worth the risk. You can quickly get the same results with most cleaners mentioned above. 

  • Water-based cleaners

Most cleaners do not work if water is present in the toilet bowl. This is impossible for a toilet cleaner because a toilet will always have water in the toilet bowl. Therefore, it is essential to check whether it can function in water while picking a cleaner.

  • Limescale removing cleaners

Limescale deposits occur when you live in a hard water supply area. Most toilet unclogging liquids specialize in getting rid of limescale. This is a factor to consider while buying a toilet cleaner. 

  • Pleasant smelling cleaners

Most toilet cleaners smell awful. So it does not hurt to check whether your cleaner has a pleasing, clean, fresh odor. There have been many good fragrances in the toilet unclogging cleaner market in recent years. 

  • Check the packaging of the cleaner bottle.

It is always best to pick a bottle with an angled head to pour the liquid under the rim of the bowl.


Will bleach help unclog a toilet?

Yes, bleach can help in dissolving clogs in your toilet. Even though bleach is not good for bigger clogs, you can get rid of smaller ones with it. To do this, pour three full cups of bleach into the bowl and let it stay for an hour before washing it down. For a better clean, use a professional drain cleaner.

How long does dish soap take to unclog a toilet?

Yes, just like bleach, dish soap can help dissolve the clog. Mix dish soap with some hot water and let it stay for thirty minutes. The dish soap will soften the clogged part, and the hot water will help your toilet flush better.

Can Coca-Cola unclog a toilet?

Yes, Coca-Cola can unclog your toilet. The reason for this is the carbon content present in this soft drink. Pour some Coca-Cola into your toilet bowl, leave it for twelve to fourteen hours, and flush it. 

Wrapping Up

As you have seen, there are multiple toilet unclogging cleaners available. Depending on your needs and the level of the clogs, you should be able to find one that best cleans your toilet clog. The first step against clogged toilets will always be your plunger and cleaner. Your cleaner doesn’t have to be quick as long as it does a thorough job of unclogging your toilet. Even though it is optional, you can choose plant-based, cruelty-free alternatives to harsh toilet cleaners. Using a professional toilet unclogger is always the step one in trying to solve the problem. Our best recommendation is the Bio-Clean Drain Septic Cleaner. It is budget-friendly, effective, and environmentally friendly. If the problem persists, you should seek the help of a professional plumber.
