5 Common Toilet Problems and How to Fix Them

A malfunctioning toilet can be a major inconvenience in any household. From a clogged toilet to a running flush, these problems can disrupt daily life and cause frustration. Fortunately, many toilet issues can be fixed without the need for a professional plumber. In this article, we will discuss five common toilet problems and provide simple solutions for resolving them.

1. Clogged Toilet

One of the most common toilet problems is a clog. A clogged toilet occurs when excessive waste or foreign objects obstruct the drain pipe, causing water to back up and the toilet to overflow. To fix a clogged toilet, you can try using a plunger.

Position the plunger over the drain hole, ensuring a tight seal, and plunge vigorously. The pressure created by the plunging motion will help dislodge the clog. If the clog persists, consider using a toilet auger, a long flexible tool specifically designed for unclogging toilets.

2. Running Flush

A running flush is another prevalent issue that can waste a significant amount of water. When the toilet continuously runs after flushing, it indicates a problem with the flush valve or the fill valve. To fix this problem, start by removing the toilet tank lid and inspecting the components.

Adjust the chain connecting the flush lever to the flapper valve, ensuring it has enough slack to allow the flapper to close completely. If the chain is not the issue, check the fill valve and adjust the water level to the recommended height. If these adjustments do not solve the problem, it may be necessary to replace the faulty valve.

3. Weak Flush

A weak or incomplete flush can be frustrating, as it may require multiple attempts to clear the bowl. This issue often results from a problem with the toilet’s flapper or the water level in the tank. Start by checking the flapper to ensure it is sealing properly. If it is worn or damaged, replace it with a new one.

Additionally, check the water level in the tank and adjust it if necessary. The water level should be approximately one inch below the top of the overflow tube. Increasing the water level can improve the flush strength.

4. Leaking Toilet

A leaking toilet can waste a substantial amount of water and lead to higher water bills. To determine if your toilet is leaking, add a few drops of food coloring to the tank and wait for about 15 minutes. If the water in the bowl changes color, it indicates a leak.

The most common cause of a leaking toilet is a faulty wax ring seal between the toilet base and the floor. To fix this, you will need to remove the toilet, replace the wax ring, and reinstall the toilet. If the leak persists, check for cracks or damage in the toilet bowl or tank and replace any faulty components.

5. Noisy Toilet

A noisy toilet can be disruptive and annoying, especially if it occurs during the night. The most common source of toilet noise is a faulty fill valve. To fix this, locate the fill valve, which is usually on the left side of the toilet tank, and adjust the float.

The float should be set at a level that allows the tank to fill to the recommended level without causing the valve to make noise. If the noise continues, consider replacing the fill valve with a new one.


While toilet problems can be frustrating, many of them can be resolved without the need for professional assistance. By understanding common issues such as clogged toilets, running flushes, weak flushes, leaking toilets, and noisy toilets, you can tackle these problems effectively. Remember, if the issue persists or seems beyond your capabilities, it’s always best to seek the help of a professional plumber to ensure a proper toilet repair.
