How To Fix a Toilet That Won’t Flush [Step by Step Guide]


A toilet that doesn’t flush is one of the most disgusting and inconvenient things that can happen in your home. Not only is it a huge mess, but it can also be a health hazard for your family and lead to water damage in your home.

Learn how to fix a toilet that won’t flush with our easy-to-follow guide. We’ll show you how to identify and solve the most common causes of this problem so you can get your bathroom back up and running in no time!

5 Reasons Why Your Toilet Won’t Flush and How to Fix It

Reason #1: The Flapper is Damaged

Your toilet won't flush because of the damaged flapper.

The flapper is a rubber gasket that sits in the bottom of your toilet and prevents overflow. If it’s leaking, water will seep through the tank and make it impossible to flush your toilet.

To fix this problem, you’ll need to replace the flapper. You can buy a new one at most hardware stores or home improvement stores.

To replace a damaged flapper, do this:

  1. Shut off the water to your toilet by turning off the valve behind it.
  2. Flush the toilet to empty the water from the bowl.
  3. Disconnect the flapper from the chain by unhooking it from the hook on the side of the tank.
  4. Remove the old flapper and replace it with the new one.
  5. Reconnect the flapper to the chain and reattach it to the hook on the side of the tank.
  6. Turn on the water to your toilet and flush it to check that it is working properly.

Reason #2: Problem With The Toilet Handle

Your toilet won't flush because of the toilet handle is broken.

If your toilet handle doesn’t budge, it could be that the flapper isn’t seating correctly or that the chain is too tight (or too loose). In this case, you’ll need to adjust the chain. This is a simple process and can be done with a pair of pliers.

To adjust the chain, do this:

  1. Drain the water from your toilet by flushing it.
  2. Remove the lid to your toilet tank.
  3. Disconnect the chain from the end of the handle arm.
  4. Adjust the chain to be a bit looser and reconnect it to the toilet handle.
  5. Turn on the water to your toilet and flush it to check that it is working properly.

Reason #3: Tank Water Level is Too Low

Your toilet won't flush because of the low water level so fill valve should be adjusted.

If the water level in your tank is too low, then there will not be enough water in the tank to create a full flush. The fix for this is simple.

You can fix this by either pouring water in the tank manually or re-adjusting the toilet fill valve. Once the water level is back up to where it should be, your toilet should start flushing correctly again.

Do this to adjust the water level of your tank using its fill valve:

  1. Locate the fill valve on the side of your tank.
  2. Turn the valve counterclockwise to open it.
  3. Fill a bucket with water and slowly pour it into the tank until it reaches the correct level.
  4. Turn the valve clockwise to close it.

Reason #4: Clog in the Drainpipe

Clogged drain pipe is one reason of why your toilet won't flush properly

If there’s a clog in your drainpipe, it could be preventing the toilet from flushing correctly. You’ll need to remove the clog and clear the pipe in order to fix the problem.

There are a few different ways you can do this, but the most common is to use a plunger. If the clog is deep down in the pipe, you may need a drain snake or pressure gun to remove it.

To use a drain snake to unclog a toilet drain, do this:

  • Shut off the water to your toilet by turning off the valve behind it.
  • Remove the drain cover from the bottom of the toilet.
  • Insert the snake into the drainpipe and push it through until you reach the clog.
  • Turn the snake clockwise to remove the clog.
  • Rinse off the snake and put the drain cover back on.

Reason #5: Bad Plumbing of the Toilet Drain Pipe

Bad pipe plumbing is also a reason why your toilet wont flush.

If the plumbing of your drain pipe has structural issues, it could be causing the toilet to flush incorrectly. There are a few different things that could be wrong with your drainpipe; this includes a leaky pipe, a broken pipe, or a misaligned pipe.

If you think there may be something wrong with the plumbing of your drain pipe, you should call a plumber to have them take a look. They will be able to tell you what’s wrong and fix it for you.

Conclusion

These are the five most common reasons why a toilet won’t flush correctly. If you’re having this problem, try one of these solutions until you find the one that works for you. If all of these solutions don’t work, it may be time to call a plumber. They will be able to quickly assess the problem and fix it for you.
