How To Fix a Toilet That Won't Flush - 4 Easy & Quick Ways

February 19, 2025

Press flush, but nothing happens? A non-functioning toilet flush is annoying, but don’t worry. You can fix most problems yourself without calling a plumber. Here are four simple ways to get your toilet working again.

1. Check the Water Supply

Make sure the cistern has adequate water in it if your toilet stops flushing. There can be no flush if there is no water! Look inside by lifting the lid. The issue might be that if the water level is too low,

The water supply is turned off
A blocked fill valve
A faulty float

Turn on the water supply if it’s off. If the fill valve is clogged with dirt, clean it with a cloth. If it’s broken, replace it. The toilet flush system needs the right water level to work properly. If the cistern isn’t filling up, the flush will be weak or won’t work at all.

2. Fix the Flush Handle and Chain

A loose or damaged handle is a frequent source of toilet bowl flushing issues. If the handle is shaky, tighten it. Inside the cistern, the handle links to a chain that raises the toilet flush mechanism. If the chain is too slack or has come undone, the toilet will not flush.

How to fix it:

Check the chain after opening the cistern lid.
If it’s disconnected, reattach it.
If it’s too loose, adjust it so there’s a slight tension.
Test the flush.

A simple chain fix can solve a non-functioning toilet flush issue. If the handle is broken, you’ll need a new one. Handles are cheap and easy to replace—just unscrew the old one and fit the new one.

3. Clean or Replace the Flush Valve

The flush valve commode controls how water moves from the cistern to the bowl. Your toilet may not flush properly if it is blocked with limescale. How to fix it:

Shut off the water supply.
Cistern should be emptied.
Examine the flush valve for debris or damage.
It may be cleaned with vinegar or replaced if it is damaged.
Reassemble everything and do a flush test.

A good toilet bowl flush mechanism is essential for a powerful flush. Over time, the flush valve may wear down, resulting in leaks and insufficient flushing. Regular cleaning extends its life.

If the flush valve appears to be in good working order, but the flush remains weak, the fault may be with the syphon. The syphon pulls water from the cistern into the toilet bowl. If it is broken, replacement is the best option.

4. Unclog the Toilet or Rim Jets

If water fills the cistern and the handle works, but the toilet flush is weak, your toilet might be clogged. The loo flush mechanism depends on a strong water flow. Blocked pipes or clogged rim jets can make the flush weak.

How to fix it:

Use a plunger to clear the blockage.
Pour hot water and baking soda into the bowl to break up clogs.
Look under the rim of the toilet bowl—small holes called rim jets can get clogged with limescale.
Use a pin or brush with vinegar to clean the rim jets.

If the flush is weak even when the cistern is full, blocked rim jets could be the cause. Keeping them clean will help the toilet flush properly.
