How to Fix a Toilet That Won’t Flush

As a homeowner, dealing with a toilet that won’t flush can be incredibly frustrating. This common issue can disrupt your daily routine and cause unnecessary stress. In this guide, we’ll explore how to fix a toilet that won’t flush, providing clear, actionable steps to solve the problem yourself. 

If the issue persists, remember that professional plumbing services are always an option.

Common Reasons a Toilet Won’t Flush

Clogged Toilet Bowl or Drain

Clogs are the most common reason for a toilet that won’t flush. They can be caused by excessive toilet paper, foreign objects, or buildup in the pipes. 

Signs of a clog include slow draining water or water rising in the bowl without flushing away.

Problems with the Flapper Valve

The flapper valve controls the release of water from the tank to the bowl. If the flapper is damaged or misaligned, it can prevent the toilet from flushing properly. 

This is often due to wear and tear over time.

Faulty Fill Valve

The fill valve controls the water level in the tank. A faulty fill valve can result in insufficient water for a proper flush, causing the toilet to malfunction. 

Symptoms include a tank that won’t fill up or overflows.

Broken Lift Chain

The lift chain connects the flush handle to the flapper. If the chain is broken or too loose, it won’t lift the flapper effectively, preventing the toilet from flushing. 

This is a simple mechanical issue that can be easily fixed.

Low Water Level in the Tank

A low water level can hinder the flushing process. Ensuring the water level is adequate is essential for proper toilet function. 

This can be caused by a misadjusted float or issues with the fill valve.

DIY Fixes for a Toilet That Won’t Flush

Tools You’ll Need

  • Plunger
  • Toilet auger (plumber’s snake)
  • Adjustable wrench
  • Screwdriver
  • Replacement parts (flapper, fill valve, lift chain)

Unclogging the Toilet

Using a Plunger

  1. Ensure there’s enough water in the bowl to cover the plunger cup. This creates a better seal.
  1. Place the plunger over the drain hole and push down and pull up vigorously. Repeat until the clog is clear.

Using a Toilet Auger

  1. Insert the auger into the drain hole and turn the handle to break up the clog.
  1. Push the auger in further if you feel resistance, then pull it out to remove the blockage.

Fixing a Flapper That Isn’t Sealing Properly

  1. Turn off the water supply to the toilet by closing the valve behind it.
  1. Drain the tank by flushing the toilet.
  1. Inspect the flapper for damage. If worn out, replace it with a new one.
  1. Ensure the chain has enough slack to allow the flapper to close completely.

Adjusting the Water Level in the Tank

  1. Locate the fill valve, usually on the left side of the tank.
  1. Adjust the float:
  • For a ball float, bend the arm gently to raise or lower the water level.
  • For a cup-style float, use the adjustment screw on the fill valve to set the desired water level.

When to Call a Professional

Signs That the Problem is Beyond DIY Fixes

  • Persistent clogs that don’t clear with a plunger or auger.
  • Significant leaks around the base of the toilet or from the tank.
  • Complex internal issues that you’re not comfortable handling.
