You don’t want a constantly running toilet in your home, right? If your toilet flapper stays open after flushing, it can be a real nuisance. You know the flapper plays an important role in the proper functioning of the toilet, and when it fails, it can cause various problems.
When the flapper stays open after you flush, it is usually because it is worn out, broken, the wrong size or the flapper hinges are clogged.
In this article, we will have a deep dive into why your toilet flapper stays open after you flush your toilet and how to fix it.
Why Does The Toilet Flapper Stays Open After Flushing?
When you flush your toilet, water rushes into the bowl to push waste out through the drain. Pressing the toilet handle lifts a rubber or plastic disk called a “flapper” up from the flush valve so that the water can flow from the tank to the bowl.
Once the waste is flushed, and the tank is empty, the flapper falls back into place sealing the tank. Thus, it can fill up again for the next flush. But how long should toilet flapper stays open? A good toilet flapper usually stays open for 3 to 8 seconds.
However, sometimes the flapper doesn’t seal properly, and water continues to leak from the tank into the bowl. However, what causes toilet flapper to stay open? This can happen for a number of reasons including:
The Flapper Is Worn Out
Over time, the flapper can become worn out or cracked, preventing it from sealing tightly. This can cause the toilet flapper to stay open after the flush. This can also cause your toilet to run constantly and sometimes even overflow.
If your toilet flapper is broken, it won’t stay shut after you flush. If the rubber ring is cracked, it can’t seal the tank to the bowl properly and will cause a leak.
Wrong Size or Weight of Flapper
Different toilets require a different size or weight of flappers. If you don’t replace your old flapper with the new one of the correct size, it won’t close properly. It will cause your toilet flapper to stay open. Add weight to toilet flapper if your toilet flapper not heavy enough.
The Chain Is Too Short
The flapper is attached to the tank by a chain, and if that chain is too short, the flapper can’t seal properly. A short chain can cause the flapper to stay open after flushing.
Too much air pressure will force the flapper open, even if it is supposed to stay shut. If the pipe has too much air pressure entering the tank, then it will make your toilet flapper stay open.
The Flapper Hinges Are Clogged
The flapper has hinges that allow it to open and close, and if those hinges are clogged with mineral deposits or debris, the flapper won’t be able to seal properly.
How To Fix A Toilet Flapper That Stays Open After Flushing?
It can be really annoying when your toilet flapper stays open after flushing, right? Not only does it waste water, but it can also be a pain to keep returning to the bathroom to flush again.
Luckily, there are a few things you can do to fix this problem. But the first thing you need to do is identify the problem and then try to fix it. And here are the steps you have to go through to fix this issue:
Replace The Worn Out or Broken Flapper
The most common reason a toilet flapper stays open after flushing is that the flapper is worn out or broken. Over time, the rubber seal on the flapper can break down and become brittle.
When this happens, it can allow water to seep through, which will cause the flapper to stay open. To fix this, you’ll need to replace the flapper.
Adjust The Chain Length
Another common reason a flapper stays open is that the chain is too short. When the chain is too short, it can cause the flapper to become dislodged from the seat.
This can also cause water to seep through and cause the flapper to stay open. To fix this, you’ll need to adjust the length of the chain.
Use the Correct Size and Weight
Flappers come in different sizes and weights. The wrong size or weight flapper won’t seal correctly if you have the wrong size or weight flapper. As a result, this will cause the toilet to use excessive amounts of water.
To fix this, you’ll need to replace the flapper with a new one that’s the correct size and weight.
Release the Air Pressure
If the flapper is the correct size but still stays open after flushing, it can be because of air pressure. If there is too much pressure in the tank, it can cause the flapper to become dislodged.
To fix this, you’ll need to release the air pressure in the tank.
Clean the Flapper Hinges
Finally, if the flapper hinges are clogged, it can also cause the flapper to stay open. This is because the clog can prevent the flapper from sealing properly.
To fix this, you’ll need to clear the clog and then adjust the hinges.
How Do You Test A Flapper Valve?
If your toilet is constantly running, it may be time to replace the flapper valve. It’s not uncommon for a toilet flapper valve to get gummed up with mineral deposits, causing it to leak. If you think your toilet flapper valve is leaking, you can do a simple test to find out.
To test whether your flapper valve is working properly, add 4 or 5 drops of food coloring to the tank. If the color appears in the bowl within 15 minutes, the flapper valve is not sealing properly and needs to be replaced.
How Do You Know If Your Flush Valve Is Broken?
Knowing the signs of a broken flush valve can help you take action quickly and avoid costly repairs. Here are some common signs that your flush valve may be broken:
1. Toilet Runs Constantly: A common sign that your flush valve has gone bad is when your toilet runs constantly. If you hear water flowing intermittently in the toilet tank, this is a sign that the flush valve is not closing fully, causing the water to continue running.
2. The Tank Fills Up Slowly: Another common sign of a broken flush valve is if it takes a long time for your toilet tank to fill up after flushing. A clogged flush valve or a broken seal can cause this.
3. The Toilet Will Not Flush: If your toilet will not flush, this is a sure sign that your flush valve is broken. This can be due to a broken seal or a clogged flush valve.
Do toilet flapper valves wear out?
Yes, toilet flapper valves do wear out over time. Toilet flapper valves are designed to be replaced periodically, as they are subject to wear and tear and the natural deterioration that comes with age.
What happens if the toilet flapper is broken?
A broken toilet flapper is a common problem that can lead to a constantly running toilet and other plumbing issues. When the flapper is broken, it prevents the flush valve from sealing off and closing off the toilet water supply. This means the water continues to run after you flush, eventually causing the water to overflow.
Is a flush valve the same as a flapper?
A flush valve is the part of the toilet tank responsible for releasing large volumes of water when flushed or activated. On the other hand, the flapper is the part of the toilet tank that seals off the flush valve when the toilet is not in use.
A toilet flapper that stays open after flushing can be very annoying and costly. Fortunately, there are some simple solutions to this issue that you can try. Based on the information above, I hope you know how to fix the toilet flapper that stays open after flushing.
Understanding the common causes and taking steps to fix your old flapper can save you from the expense of a major plumbing repair.
