Why Does My Toilet Not Flush

Why Does My Toilet Not Flush? Here’s The Fix!

In any home, a toilet that won’t flush may easily become a big annoyance. Although it’s an urgent problem, it can usually be fixed without calling for expert plumbing assistance. 

It can save time, money, and a great lot of irritation to know the common causes of a faulty toilet and how to remedy them. 

We’ll look at a number of potential causes of your toilet’s malfunction and offer workable fixes in this in-depth tutorial.

Common Reasons Why Your Toilet Won’t Flush

1. Clogged Toilet

A clog in the plumbing is one of the most frequent causes of a toilet not flushing. Numerous things, such as using too much toilet paper, flushing the wrong things, or accumulating garbage, can cause clogs.

2. Low Water Level in the Tank

There won’t be enough water in the tank to produce a powerful flush if the water level is too low. A misaligned float or a broken fill valve may be the source of this problem.

3. Flapper Problems

During a flush, the flapper—a rubber component inside the toilet tank—lifts to allow water to enter the bowl. A complete flush may be impeded if the flapper is worn out, misplaced, or not sealing correctly.

4. Chain Issues

Flushing issues might arise from a tangled, too-loose, or too-tight chain connecting the flush handle to the flapper. The flapper may not be lifted sufficiently or at all if the chain is not the proper length.

5. Blocked Rim Holes

The small holes under the rim of the toilet bowl, known as rim jets or rim holes, can become clogged with mineral deposits or debris. These holes are essential for directing water into the bowl during a flush.

6. Broken Lift Arm

The rod that joins the handle to the chain and flapper is called the lift arm. The lift arm may not work properly and stop the toilet from flushing if it is broken or bent.

7. Problematic Fill Valve

A faulty fill valve can cause issues with the water level in the tank. If the fill valve is not working correctly, it might not refill the tank properly after a flush.

8. Vent Pipe Blockage

Vent pipes, a feature of plumbing systems, let out air and keep sewage gasses out of the house. A clogged vent pipe can create a vacuum in the plumbing system, which can interfere with flushing.

How to Fix a Toilet That Won’t Flush

1. Unclog the Toilet

You can use a plunger, a toilet auger, or a vinegar and baking soda mixture to unclog a toilet. Here’s a detailed how-to: 

Using a Plunger:

  1. Ensure there is enough water in the bowl to cover the plunger’s rubber part.
  2. Position the plunger over the drain hole and push down gently to create a seal.
  3. Push and pull the plunger rapidly without breaking the seal.
  4. After several plunges, lift the plunger to see if the water drains.
  5. Repeat as necessary until the clog is cleared.

Using a Toilet Auger:

  1. Insert the auger into the toilet bowl and push it gently into the drain.
  2. Crank the handle to extend the auger into the pipe.
  3. When you feel resistance, twist the handle to break up or catch the clog.
  4. Pull out the auger, removing any debris.

Using Baking Soda and Vinegar:

  1. Pour one cup of baking soda into the toilet bowl.
  2. Follow with one cup of vinegar.
  3. Allow the mixture to sit for 30 minutes.
  4. Flush the toilet to see if the clog is gone.

2. Adjust the Water Level in the Tank

To adjust the water level in the tank:

  1. Remove the tank lid and check the water level. It should be about one inch below the top of the overflow tube.
  2. If the water level is too low, adjust the float. For a float cup fill valve, pinch the clip on the side of the float and slide it up. For a ball float, bend the arm upward.
  3. Flush the toilet and check the water level again. Adjust as necessary.

3. Inspect and Replace the Flapper

To inspect and replace the flapper:

  1. Turn off the water supply to the toilet.
  2. Remove the tank lid and flush the toilet to empty the tank.
  3. Disconnect the chain from the flapper and unhook the flapper from the overflow tube.
  4. Inspect the flapper for damage. If it’s worn or warped, replace it with a new one.
  5. Attach the new flapper to the overflow tube and reconnect the chain.
  6. Turn on the water supply and test the flush.

4. Fix Chain Issues

To fix chain issues:

  1. Open the tank lid and check the chain length. It should have about 1/2 inch of slack when the flapper is closed.
  2. If the chain is too loose or tangled, adjust it by hooking it to a different hole in the flush lever or trimming excess links.
  3. If the chain is too tight, lengthen it by moving the hook to a different hole or adding extra links.
  4. Test the flush to ensure the chain lifts the flapper properly.

5. Clean the Rim Holes

To clean the rim holes:

  1. Use a small mirror to inspect the holes under the toilet rim.
  2. Use a wire hanger or a small brush to clean out any debris or mineral buildup.
  3. Pour white vinegar into the overflow tube and let it sit for an hour to dissolve any remaining deposits.
  4. Flush the toilet to rinse out the rim holes.

6. Replace a Broken Lift Arm

To replace a broken lift arm:

  1. Turn off the water supply and empty the tank.
  2. Disconnect the chain from the flush handle.
  3. Remove the nut securing the handle to the tank and take out the broken lift arm.
  4. Install the new lift arm and secure it with the nut.
  5. Reattach the chain and adjust the length if necessary.
  6. Turn on the water supply and test the flush.

7. Replace the Fill Valve

To replace a faulty fill valve:

  1. Turn off the water supply and flush the toilet to empty the tank.
  2. Disconnect the water supply line from the fill valve.
  3. Remove the nut securing the fill valve to the tank and take out the old valve.
  4. Install the new fill valve according to the manufacturer’s instructions.
  5. Reconnect the water supply line and turn on the water.
  6. Adjust the water level and test the flush.

8. Clear the Vent Pipe

To clear a blocked vent pipe:

  1. Locate the vent pipe on your roof.
  2. Use a flashlight to check for visible blockages such as leaves, debris, or nests.
  3. Use a garden hose to flush out the vent pipe. Start with a low-pressure stream to avoid damaging the pipe.
  4. If the blockage persists, consider using a plumber’s snake to clear it.

Preventive Measures to Keep Your Toilet Functioning Properly

Preventing toilet issues can save you from future headaches and repair costs. Here are some preventive measures to ensure your toilet functions properly:

  1. Use Toilet Paper Sparingly: Use a reasonable amount of toilet paper to avoid clogs. Consider using a thinner or septic-safe toilet paper.
  2. Avoid Flushing Inappropriate Items: Never flush items such as wipes, feminine hygiene products, paper towels, or cotton balls. Dispose of these items in the trash.
  3. Regular Maintenance: Periodically inspect and clean the components inside the toilet tank. Replace worn-out parts promptly.
  4. Install a Water Softener: If you have hard water, consider installing a water softener to prevent mineral buildup in your toilet.
