A malfunctioning toilet can be a major inconvenience in any household. When your toilet won’t flush, it can be frustrating and lead to unpleasant odors in your bathroom. Fortunately, many toilet flushing problems can be fixed easily without calling a plumber. In this article, we’ll cover some common causes of a toilet that won’t flush and how to fix them.
Tools and Supplies Needed:
- Plunger
- Bucket
- Gloves
- Toilet auger
- Replacement flush valve or flapper
Step 1: Check the Water Level in the Tank
The first step in fixing a toilet that won’t flush is to check the water level in the tank. The water level should be just below the top of the overflow tube. If the water level is too low, the toilet won’t flush properly. To adjust the water level, use the float to adjust the fill valve. If the fill valve is broken, you may need to replace it.
Step 2: Check for a Clog
A clog in the toilet bowl or the drain line can cause the toilet to not flush properly. Start by using a plunger to try and clear the clog. Fill the plunger with water and push it down over the drain hole in the toilet bowl. Apply firm pressure to create a suction, and then release. Repeat this process several times until the clog clears.
If the plunger doesn’t work, you may need to use a toilet auger to clear the clog. A toilet auger is a flexible snake-like tool that can navigate through the curves of the drain line. Insert the auger into the toilet bowl and turn the handle until the clog is cleared. Be careful not to scratch the porcelain bowl.
Step 3: Check the Flush Valve or Flapper
If the water level and drain line are clear, the problem may be with the flush valve or flapper. The flush valve controls the release of water from the tank into the bowl, while the flapper controls the flow of water from the tank to the bowl.
To check the flush valve or flapper, remove the lid from the toilet tank and flush the toilet. Watch the flush valve or flapper to see if it opens and closes properly. If the flush valve or flapper is damaged or worn, it may need to be replaced. Turn off the water supply to the toilet and drain the tank before removing the old valve or flapper.
Step 4: Replace the Flush Valve or Flapper
To replace the flush valve or flapper, follow these steps:
- Turn off the water supply to the toilet and drain the tank.
- Remove the old flush valve or flapper from the bottom of the tank.
- Install the new flush valve or flapper according to the manufacturer’s instructions.
- Turn the water supply back on and fill the tank.
- Test the toilet to make sure it flushes properly.
If the toilet still doesn’t flush properly after replacing the flush valve or flapper, there may be a problem with the toilet’s venting system. In this case, it’s best to call a plumber for further assistance.
Preventing Future Toilet Clogs
To prevent future clogs and toilet flush problems, follow these tips:
- Don’t flush anything other than toilet paper and human waste down the toilet.
- Install a drain strainer to catch hair and other debris before it enters the drain line.
- Regularly clean the inside of the toilet bowl and tank to prevent buildup of mineral deposits and other debris.
