Do you experience a running toilet after flushing? Well, a running toilet after flushing is quite annoying, leave alone the expense it comes with. A toilet that keeps flushing by itself wastes a lot of water, which means that your water bill will go high.
If the problem is not fixed in good time, the amount of money you spend on your water bill might be so high that it might force you to cut other expenses. There are different reasons why a toilet keeps flushing by itself even after being flushed. Here are some of the causes of a ghost flushing toilet:
Problem With the Toilet Flapper
The most likely culprit is your toilet flapper. When the flapper is not working properly, you will experience a ghost flushing toilet. The flapper is a rubber piece that sits on top of the flush valve and blocks the drain to prevent water from flowing down after the cistern fills with water. If it is not working properly, there will be no blockage, and thus water will flow freely down the drain, causing a ghost or phantom flushing toilet.
A faulty or old flapper can cause a phantom flushing toilet. If you have an old toilet, it is best to replace the flapper with a new one. You can also try to adjust the position of the flapper so that it completely covers the flush valve opening. Flappers are readily available in most hardware stores.
Before replacing the flapper, drain the water from the tank, shut off the water supply to the toilet, and flush the toilet to drain water. If the flapper chain is too long, you'll need to shorten it. If it's long, it will get caught underneath, and you won't get a good seal, and the toilet will continue to run. If you suspect your toilet is old, replace it with some of the best flushing toilets available.
Toilet Keeps on Its Own Due to a Leaky Flush Valve Seal
If your toilet keeps on its own, it could be due to a leaky flush valve seal. The most common cause of a leaky flush valve seal is mineral buildup, but there are other culprits as well. If your toilet does not adequately seal off the water supply when you close the flapper, water will continue to flow into the bowl, and your toilet will keep running.
If the flapper seal leak is small, phantom flushing may not happen very often. But as the leak grows the toilet will keep flushing by itself on a more regular basis. If your toilet leaks, you may see other signs such as repeated or constant whirring or hissing sounds, water in the toilet bowl will move on its own, your toilet water will keep running after the flush, and your consistent water bill will be on the rise.
To ensure you're looking at a leaky toilet, add a few drops of food coloring to the toilet tank and wait a while. If you see the colored water appear on the toilet bowl, then there's a leak somewhere on the tank. Don't forget to flush the colored water away, so you don't end up with a stained toilet bowl.
Problem With the Toilet Refill Tube
The next most common reason for a constantly flushing toilet is a problem with the toilet refill tube. The purpose of the toilet refill tube is to bring water from the fill valve into the overflow pipe once the flush is complete and the tank is refilling.
If this tube becomes clogged or pinched, it can cause water to continuously run into the overflow pipe and cause the toilet to flush constantly. You can check the toilet refill tube by removing the lid to the tank and inspecting it. If you see any water running from the tube into the overflow pipe, then that's likely your problem.
In some cases, you may be able to clear the clog or pinch yourself. The refill tube may also extend deep into the overflow tube, so you may need to shorten it. Pull the tube out of the overflow and hold it just above the opening of the overflow and trim it off there.
Clip it to the side of the overflow tube to keep it in place. Note that the reason this causes your toilet to run is that the refill valve will create a suction effect that pulls water out of the fill valve.
Defective Toilet Float
The next most common reason a toilet keeps running is a defective float. The float is the part of the toilet that allows water to enter the tank and then shuts off the flow of water when the tank is full.
There are two types of floats: float balls and float cups. Float balls are more common and look like large, hollow balls. Float cups are less common and look like a plastic cup that sits on top of the water.
If your toilet has a float ball, check to see if it is cracked or broken. If it is, you will need to replace it with a new one. To do this, turn off the water to the toilet, flush the toilet to empty the tank, and then remove the lid.
Remove the old float ball and take it to a hardware store to find a replacement that is the same size and shape. If your toilet has a float cup, check to see if it is cracked or broken. If it is, you will need to replace it with a new one. Look for some of the most powerful flushing toilets with powerful balls that will give you a clean and powerful flush.
When you have found your replacement, install it by putting the new float ball or cup in the same place as the old one. Then, reattach the fill valve to the top of the tank and turn on the water. Test your toilet to see if it is flushing properly. If it is, you have successfully repaired your toilet, and it should no longer keep flushing.
Faulty Flush Valve Gasket
Next on the list of your toilet troubles is your flush valve gasket. This is a rubber seal that is located between the tank and the bowl. If this gasket is not sealing properly, water will leak from the tank into the bowl, causing your toilet to keep flushing. When it stops working as it should, it will lead to toilet leaks, and you'll be faced with a phantom flushing phenomenon.
Sometimes, the flush valve gasket and the tank to bowl gasket may fail, resulting in a water leak from the tank into your floor. To fix this problem, you will need to replace the flush valve gasket with a new one. To do this, simply remove the old gasket and replace it with a new one. These are easy fixes that you can do on your own without calling in plumbing service for help.
