Why does my toilet run then stop then run then stop?

The most likely reason your toilet runs and stops intermittently is that there is a problem with the fill valve. The fill valve is responsible for filling the tank with water after you flush the toilet, so if it is malfunctioning, it may fill the tank in fits and starts – first running for a few seconds, then stopping, then running again and then finally shutting off when it has finished filling the tank.

If a fill valve is failing, it may need to be replaced. You can also try adjusting the fill valve gently to see if the runs and stops will stop. If these solutions don’t work, you may need to call a professional plumber to diagnose and fix the problem.

How do you fix a toilet that runs on and off?

First, you should start by turning off the water supply to the toilet. This can usually be done by turning off the valve on the wall behind the toilet. After the water supply is shut off, flush the toilet until the tank is empty.

Next, remove the tank lid and inspect the toilet’s internal parts. If any of the parts are damaged, such as the fill valve, float valve, flapper, flush valve, or chain, these should be replaced. If you’re unsure of how to replace these parts, a local plumber can usually help.

Once any necessary parts are replaced, open the inlet valve, allowing water back into the tank. After the tank is full, use the fill valve to adjust the water level, making sure it’s slightly below the overflow pipe.

Next, adjust the float valve, if necessary. The float should be set slightly below the overflow pipe. This will ensure that the toilet doesn’t fill up too high and overflow.

Finally, inspect the flapper. Make sure that it is closing completely and not sealing too tightly, as this can cause water to run. After all adjustments have been made, the toilet should no longer be running.

How do you reset a running toilet?

Resetting a running toilet is not a difficult task, but it is important to diagnose the cause of the problem before attempting to reset the toilet. The first step is to check the float, as this is often the cause of a running toilet.

If the float is stuck or jammed, or simply too high or low, this can lead to a running toilet. To adjust it, turn off the water supply and flush the toilet. Then unscrew the lid of the tank and adjust the float arm so it sits roughly an inch or so above the surface of the water.

The next step to reset a toilet is to check and adjust the toilet’s fill valve. If the fill valve is set too low, the water in the tank won’t be able to completely fill the bowl, leading to a running toilet.

To test this, flush the toilet, and then adjust the water height on the fill valve so it’s just below the refilling level when the toilet is flushed. Finally, replace the lid on the tank and turn the water supply back on.

If these steps do not fix the running toilet, then the problem could be coming from the flapper or flapper chain. To fix this, lift the flap valve and flush the toilet. Then try to adjust the height of the flapper so it sits in the correct position, and ensure the chain attached is neither too short nor too long.

If the valve is worn or corroded, it may need to be replaced.

Ultimately, if these steps do not fix a running toilet, then it may need to be replaced. However, with a bit of patience, the causes of a running toilet can often be fixed.

What is the most common cause of a running toilet?

The most common cause of a running toilet is a faulty flapper valve. The flapper valve is a rubber seal that opens and closes to regulate the water flow from the tank to the bowl. When the flapper is old, warped, or has an uneven seal, the toilet can run constantly, leading to an increase in water usage and associated costs.

In some cases, the flush handle may be loose, which is oftentimes caused by worn out parts or when debris gets stuck in the flush mechanisms, resulting in a running toilet. Additionally, too little or too much water in the tank can cause it to run.

A simple adjustment of the water level can help fix a running toilet. In extreme cases, it may be necessary to replace the flapper or flush valve entirely.

Should I be worried about a running toilet?

Yes, you should be worried about a running toilet because it could be wasting hundreds of gallons of water every day. Not only will this cause a jump in your water bill, but it may also be causing significant damage to your plumbing.

If the running doesn’t stop, your plumbing will be liable to severe water damage and could result in costly repairs. Even worse, the overflowing water from a running toilet may seep into other parts of the house, causing further damage.

To stop the running toilet, you should check for a flapper that isn’t sealing properly or a float that isn’t adjusted correctly. If these adjustments don’t do the job, you may need to call a professional to take a look.

Fixing the issue sooner rather than later is important as costs can add up quickly.

Why does my toilet keep running even after replacing flapper?

If you have already replaced the toilet flapper and it is still running, the issue may be with the fill valve. The fill valve is responsible for controlling how and how much water the toilet tank refills after it is flushed.

It will refill your tank, and then stop when the tank has been refilled. If this valve is not functioning, the water will continue to run into the tank and out the flapper which causes the toilet to run nonstop.

In this case you may need to replace the fill valve or adjust it if it is adjustable.

It is also possible that the flapper itself is the problem; this may be due to incorrect installation, corrosion, or general wear and tear. To test if the flapper is causing the running, check to make sure it is properly seated on the flush valve and the water is not leaking around the edges.

You can also test the flapper by inserting a few drops of food coloring into the tank and if the color shows up in the bowl after a few minutes, the flapper is likely leaking. If it is, you will need to replace it.

What is the most common problem that occurs when the toilet won’t stop running?

The most common problem that occurs when a toilet won’t stop running is an issue with the flapper. The flapper is the rubber piece at the bottom of the tank that seals the water in until the toilet is flushed.

Over time, the flapper can become worn and cracked, allowing water to continuously leak into the bowl and cause the toilet to continuously run. In order to fix the issue, the flapper will need to be replaced.

Some also recommend cleaning and lubrication the flapper’s hinges in order to extend its life. Other potential issues that can cause a toilet to run can include a faulty fill valve, a worn-out wax seal, or a clogged toilet.

However, a faulty flapper is the most common problem.

How do you know if your toilet needs a new flapper?

If your toilet isn’t flushing correctly, it may be time to replace the flapper. Some tell-tale signs you need to replace the flapper include erratic flushing and the water in the tank not completely draining.

If you can see that the flapper has deteriorated with age, or if it has cracks or chips, it should be replaced as soon as possible. In addition, if you can hear water running from the tank after the toilet has been flushed, or if you can hear the cistern refilling constantly, these are also indications that the flapper may need to be replaced.

Lastly, if toilet takes a long time to refill or if it is not flushing very effectively, it could signal that the flapper needs to be changed.

How do you know the flapper is bad in toilet?

First, if your toilet is running constantly or not flushing as it should, it could be a sign that the flapper is bad. Additionally, if you can hear water trickling into the tank even when it shouldn’t, the flapper is likely to blame.

If you’re able to view the flapper, look for signs of wear and tear such as cracks, missing pieces, and even corrosion. Finally, when the water in the tank is not rising and the bowl is not filling with water, the flapper could be stuck in a closed position.

If any of these signs are present, it’s likely that your flapper is bad and needs to be replaced.

What happens if you don’t replace toilet flapper?

If you don’t replace your toilet flapper, it can cause a variety of issues. Over time, the flapper can become corroded and worn out, leading to water leaks, decreased efficiency, and higher water bill costs.

Additionally, the flapper may no longer seal properly, resulting in excess water being used with each flush. Additionally, failure to replace the flapper can lead to mineral build up, resulting in clogs and slow flushes.

To prevent these issues from occurring, it is important to inspect and replace your toilet flap every 3-5 years.

How much does a plumber charge to replace a flapper?

The cost of a plumber to replace a flapper depends on several factors, including the complexity of the job, the type and size of the flapper that needs to be replaced, the accessibility of the flapper and the plumber’s labor rate.

Generally, the price for replacing a flapper can range anywhere from around $50 to several hundred dollars. In addition, some plumbers may charge a trip fee or service call fee on top of the cost for the replacement.

If the job requires additional repairs or parts, the cost could be higher. It’s best to get multiple estimates from different plumbers to ensure you are getting the best deal on any services you need.

How often should toilet seals be replaced?

Toilet seals should be replaced every two to three years, depending on the type of seal used. It is recommended that seals be inspected annually for signs of wear and tear and replaced soon after if necessary.

If the toilet seal has a visible crack, it should be replaced immediately. Toilet seals are responsible for creating a water-tight connection between the toilet and the sewer pipe. Without a functioning seal, water can leak from the toilet and damage the floor or even worse, a sewage backup can occur.

Replacing the seal regularly can help prevent these issues from occurring.

How do you fix a phantom flush?

A phantom flush is when a toilet continues to run after it has been flushed and the tank has refilled. This is usually caused by a problem with the flapper valve located inside the tank. In order to fix this problem, you will need to take the following steps:

1. Turn off the water supply to the toilet. This can be done by turning the shut off valve located behind the toilet clockwise.

2. Flush the toilet to completely empty the tank.

3. Remove the bolts and lid from the tank.

4. Reach inside and locate the flapper valve. This should be at the bottom of the tank.

5. Remove the flapper valve and inspect it. If it is cracked, worn or bent, it should be replaced. This can be done by purchasing a replacement flapper valve from your local home improvement store and following the instructions included with the valve.

6. Once the replacement flapper valve is installed, reassemble the tank lid and bolts and turn the water supply back on.

7. Test the toilet by flushing it at least two to three times to ensure that the phantom flush has been corrected.

How do you stop ghost flushing?

To stop ghost flushing, the first step is to identify the cause. It is most often caused by a worn out flapper valve, which needs to be replaced in order to fix the issue. To check the flapper valve, start by removing the top of the tank lid and looking for a rubber or hard plastic disc.

If it appears worn, cracked, or discolored, that may indicate that the flapper valve is old or damaged and needs to be replaced.

After finding and replacing the flapper valve, another common cause of ghost flushing is a too-low water level in the tank, which can occur when the float needs cleaning or adjusting. To check this, look for a round plastic object connected to the fill valve inside the tank and adjust it if need be.

Additionally, if the flush handle sticks or remains in the down position after a flush, it could be caused by a kinked or worn out chain or handle, and replacing the chain and handle may help to fix this issue.

Finally, faulty internal components, such as a fill valve assembly, may also cause ghost flushing. In this case, the entire unit may need to be replaced. If you are unfamiliar with repairs of this kind, it is best to consult a professional plumber to help make sure the problem is resolved and fixed properly.

What causes phantom toilet flushes?

Phantom toilet flushes are caused by a variety of factors. One of the main causes is air in the pipes, which causes the water to vibrate and create a “flushing” sound. This can be caused by faulty valves or too much water pressure in the pipes.

In addition, certain toilet parts can loosen over time, allowing water to randomly escape. This can lead to random and sometimes loud bursts of sound. In some cases, the inlet valve, which is responsible for admitting water into the toilet tank, can be weak and cause the tank to fill up with water more than it should.

This can also lead to phantom toilet flushes. Finally, faulty flappers, which are responsible for controlling the flow of water in and out of the tank, can cause random and sometimes frequent flushing noises.
