Toilet Repair: How to Fix Common Issues

A toilet is one of the most indispensable fixtures in the home, but it's often ignored until it starts to malfunction. It can be frustrating when a toilet is not functioning correctly, especially when you need it. A simple problem like a running toilet can cause high water bills that you would not have expected. In this blog post, we will discuss some of the most common toilet repair issues, how to fix them, and when to call in a professional.

A Running Toilet

This is one of the most common toilet problems that can lead to a high water bill if not addressed promptly. A running toilet typically occurs when the flapper valve (a rubber piece that seals the flush valve) is worn out or stuck. To fix this issue, turn off the water supply valve behind the toilet and replace the flapper valve. If that doesn't work, the flush valve or fill valve may be the culprit, and you may need professional help.

Clogged Toilet

A clogged toilet is another issue that everyone has probably experienced at some point. The best way to fix this issue is by using a plunger. Apply pressure gently to the plunger handle, creating a vacuum that will loosen and push the clog through the drain pipe. If that doesn't work, try using a toilet auger, but be careful not to scratch the porcelain finish. If both methods fail, it could mean there's a more significant blockage in the sewer line, and a plumber will be needed.

Weak Flush

A weak flush could be due to the water level not reaching its optimal height or an issue with the flush valve. If the water level is low, adjust the float to raise the water level, and check the water supply valve if it's partially closed. If the flush valve is the problem, replace it and see if that makes a difference.

Leaky Toilet

A leaky toilet can cause damage to the flooring, subflooring, and the ceiling below the bathroom. The leak could be from the tank bolts, the wax ring under the toilet, or the water supply line. Tighten the tank bolts carefully, and ensure the toilet wax ring is correctly installed. If the leak persists, put food coloring into the tank and check for any colors that appear in the bowl. If the colors appear, it's time to replace the flush valve or fill valve.

The Toilet Won't Flush

If your toilet tank won't fill, you may have a failing fill valve. Remove the fill valve's cap and turn it counterclockwise to adjust the water level. If the toilet fails to flush altogether, you may have something stuck in the toilet trap, causing a blockage. If you can't remove the blockage yourself, you will need a plumber's help.


In conclusion, toilet repair is not as tricky as people imagine, and the problems are fixable if you follow the right procedures. Some common issues include a running toilet, a clogged toilet, a weak flush, a leaky toilet, and a toilet that won't flush. Remember to turn off the water supply before attempting any DIY repairs. If you can't fix the issue, don't hesitate to call a professional plumber to avoid more significant problems. A functional toilet leads to improved hygiene, reduces water wastage, and keeps your home healthy.
