It may be inconvenient when the toilet stops flushing or has much less force while flushing since it is one of the most frequently utilized plumbing fixtures in the home. You need to fix the toilet flushing issues before you can fix this.

A damaged float, low water level, a broken chain, a faulty flapper, rim jet jams, or a blocked drain that has to be cleaned with a plunger are some of the many possible causes of a toilet not flushing.

Tools To Fix a Toilet That Won’t Flush

To clear the toilet and free the siphon jet, you may use a few items if unsure how to drain the water.

  • Brush
  • Plungers  
  • Call a plumber

Just Slightly Congested

Our standard operating procedure dictates that the outflow drain be unobstructed. If it isn’t flushing entirely, this might be one of the causes. You should check the toilet bowl twice, even when you’re sure there’s nothing in there.

You’ll need to use a plunger to remove water in the toilet bowl to do this. If you use too much paper towels or toilet paper, it might partially clog the drain.

To ensure the drain isn’t clogged, plunge the toilet for 10 to 20 seconds. Because of the potential overflow, we do not recommend flushing the toilet if the water level is already high.

You will need to remove the particles from the pipe personally since not even toilet cleaners can get them all. If your toilet is partially clogged, this is the most common cause for using toilet paper to unclog it.

Verify The Levels Of The Water

The video above shows that the water level must stay at a certain height to keep the toilet tank functional.

The toilet stands out since it is built entirely of pulleys and levers. It can function without the use of electricity or any electrical devices.

Because the water levels must be uniform with the required levels, we clarify this idea by saying it must be at a certain height.

When the water level drops too low, the float and toilet flapper won’t activate to turn off the water. As a result, the bowl will eventually overflow. As you flush, ensure the water level changes and doesn’t stay the same.

Overloaded Float

Even though this is quite unusual, verifying it is still in one piece is prudent. The flushing valve cannot be turned off due to a stuck or damaged float.

As a result, the toilet bowl will never be filled with water since the water supply is never turned off. The “balloon-like” device that serves as the shut-off valve will float when it comes into contact with water. Therefore, this is quite unusual.

But if it’s the one that can change its form, it can get stuck. It is either played with or struck the bowl with force. It’s uncommon, but we want to be cautious, just in case.

To resolve this, remove the lid from the toilet tank and check that the chain is attached to the lever. Proper flushing should begin when you raise the chain; the float ball should begin to sink.

The chain may be removed if the toilet does not flush, even when flushed slowly.

Siphon Jet Blocked

To facilitate free water flow, the siphon jet propels it down the “S-tube” from the bottom of the bowl.

Do you find the siphon jet confusing? You can find the location of the siphon jet and how to unclog it in this video.

The water is propelled down the tube by the siphon jet, as shown. Minerals and discarded toilet paper often obstruct the toilet’s siphon jet. Check the jet openings to see if they are clogged and if your toilet has a siphon jet.

You only need a little plunger or toilet bowl cleanser to unclog a siphon jet (or clogged input holes). This may help free the jet of any mineral deposits or other accumulations of minerals.

Verify that the water is being sent down the toilet and that the flushing mechanism works properly. These tiny input pores get clogged and need to be unclogged weekly.

A broken chain or a disconnected lever

Take off the top of the tank and locate where the outside lever attaches to the interior chain or plastic part. If there is one, the toilet tank chain has probably broken loose and fallen off.

Since the toilet is flushed several times daily, detachment is common. The toilet tank will gradually drain as a consequence of this.

Fixing this is as simple as reattaching the chain to the inner handle. Glue or waterproof tape may keep the chain attached to the lever if you’re worried about it falling off again.

Despite the ease of this fix, it may be a source of frustration for those who need to become more familiar with toilets.

The Chain Is Stuck

Finally, check to see if the chain becomes trapped on the flapper or any component as it opens and shuts; blocked things aren’t the only possible reason the toilet won’t flush.

Modern toilets should be fine since the chain is supposed to be snug enough to the lever that there shouldn’t be any overhand. On the other hand, vintage toilets were constructed with a lengthy loose chain.

You may purchase a new level for the toilet tank or make some fast modifications to the one on your toilet if it has a lengthy chain. The problem can be the slack chain.

The toilet could seem blocked, but there’s no need to be scared to remove the tank cap and try several things.

Following these steps, flushing the toilet should be a breeze.


In conclusion, when toilets are partly blocked in the drain pipe or siphon jet, they may not flush properly even if they are not clogged. Clear all the obstructions in these spots to restore your flush’s smooth operation.

Most vulnerable to breakdowns are multi-child households with limited access to restroom facilities. Frequent usage might lead to malfunction if not properly cared for and maintained. The toilet won’t flush properly as a result of this.

Always take the initiative rather than the easy way out when dealing with restrooms. After thoroughly cleaning the siphon jet, double-check that the lever is securely attached and ensure the flushing pattern is uninterrupted.

Finally, ensure the water levels increase and release appropriately by running the test.
