Why does the toilet flapper close too soon?

There are several reasons why a toilet flapper may close too soon. 

Cause1. The toilet flapper closes too quickly Because The flapper is too heavy. 

The major issue is that the toilet flapper doesn’t stay open long enough. The flapper is too heavy, causing the flapper to close too fast. 

The flapper must be open when we flush the toilet, so the water rushes through the bowl and clear the waste. The flapper sits on the flush valve and creates a seal to stop the water from the tank to the bowl.

If you recently changed the flapper, it must be not the right flapper as the old one. It is heavy and can’t stay long for a period. It is heavy enough to fall again and again.

Cause2. Toilet flapper chain too long to toilet flapper closing immediately.

One common reason is that the chain connecting the flapper to the lever is too long or loose, and that’s why the flapper immediately closes after decreasing the water pressure. You might need to tighten the flush lever chain.

You may notice a chain joint with a flush lever and flapper if you open the tank lid. This chain determines how widely open the flapper is while on flush.

You may find yourself in this situation if the chain is too loose. This can be easily fixed by lengthening the chain. 

Cause3. The flapper itself is worn out that’s why the toilet flapper closing too fast

Another possibility is that the flapper is worn out and no longer standstill. Hard water and continuous flushing can damage the flapper over time. It may help you, if the toilet flapper sticks somehow in the tank then use 2 tricks to remove it.

How can I keep my toilet flapper from closing too quickly?

Fixing a toilet flapper that closes too fast is relatively easy and cheap; just follow any option according to your reasons.

Option1. How to fix a toilet flapper that closes too quickly by Adjusting the Chain

The chain is loose to cause the flapper close fast, just shorting the length.

· Pull out the hook from the flush lever handle

· Now move one gap ahead.

· Check the length by flush once, see again close fast or not; if so, do one more gap and hook the chain.

Option2. Add floating Thermocol

Thermocol helps the flapper float. Cut about 2-inch Thermocol and make a small hole at the center.

Now pull out the chain, attached with a flush handle, and insert it through it.

Place the Thermocol near the flapper. Again Check by flushing.

Option3. Add a float ball near the flapper.

When it is determined that the toilet flapper is closing too fast, a float ball can be added near the flapper to stop it from closing so quickly. 

· This will allow more time for the water to flow out of the tank and into the bowl, which will help reduce the amount of noise created.

This will help the flapper close more quickly and prevent the water from rushing out. Whichever method you choose, make sure to test it out to ensure that the toilet is flushing properly.

How do I make my toilet flapper stay open longer?

One way to make your toilet flapper stay open longer is to add a small weight to it. You can use a washer or a small rock. 

Another way to keep the flapper open is to add a little bit of Vaseline or cooking oil to the hinges. This will allow them to move more easily and keep the flapper open for a longer period of time.

If you have a chain on your flapper, you can also add a small clip to keep it in place.
