What Triggers Toilet Won’t Flush?

Lastly, issues in the drain line can also stop your toilet from flushing effectively. In short, the main reasons your toilet won’t flush are:

  • Disconnected Lever or Faulty Handle

  • Clogged Toilet

5 Effective Ways to Fix a Toilet Won’t Flush

Having a toilet that won’t flush can be a real headache. But don’t worry; fixing it is often easier than you think.

Here are five effective ways to get your toilet working again

1. Repair or Change the Faulty Flapper

Over time, it can wear out or get misaligned. Turn off the water supply to your toilet to fix it.

Then, flush to drain the water from the tank. Unhook the old flapper and install a new one, which you can find at any hardware store.

Make sure it’s properly aligned and creates a good seal. This simple change can often solve flushing problems.

2. Adjust the Water Level

Gently bend this arm to adjust the float’s height. This will change when the water stops filling the tank.

Aim for about an inch below the overflow tube. This adjustment ensures your toilet has enough water for a strong flush.

3. Unclog the Toilet

Use consistent push-and-pull movements to loosen the clog.

If the plunger doesn’t work, try a toilet auger. Gently feed it into the bowl, aiming for the clog.

Turn the handle to break apart or grab the clog. Remove any debris you find, and then flush the toilet to check if it works properly.

This method is effective for most clogs, restoring your toilet’s functionality without needing professional help.

4. Clear the Drain Line

In such cases, a standard plunger might not suffice.

You’ll likely need a longer plumbing snake, a tool designed to navigate through your pipes and reach deeper blockages.

Carefully feed this snake into the drain, twisting and pushing to dislodge any obstructions. However, if you need more confidence in your plumbing skills, it’s wise to seek professional help.

Experienced plumbers have the right tools and expertise to effectively clear the drain line without causing any damage to your pipes.

They can also identify if the problem is more complex, ensuring a thorough and lasting solution to your toilet’s flushing woes.

5. Clean and Unclog Rim Jets

To clean them, turn off the water and flush to empty the bowl.

Use a small brush (like an old toothbrush) dipped in vinegar to scrub the jets. This removes buildup and improves water flow, helping your toilet flush more effectively.


Fixing a toilet that won’t flush is often straightforward. Whether replacing a faulty flapper, adjusting the water level, unclogging the toilet, clearing the drain line, or cleaning the rim jets, these steps can effectively solve most issues.

With the right approach, you can quickly get your toilet working again.
