Why Toilet Flapper Won’t Close After Flushing
More than 6 reasons are present behind a non-closing flapper after flush. Check and find out which one is in your case.
1. Toilet Flapper Not Closing because of the Chain
The flapper chain is most likely the causative agent for a not closing flapper after every flush.
The chain is present in the toilet tank attached to the flush lever/ handle and the flapper. Therefore, whenever you flush, the toilet the chain pulls up the flapper, and water goes to the bowl and clears the matter.
If the chain is too tight, the flapper does not drop properly, which you can see. Are you recently changing the flapper or changing the chain? After installing the flapper, it seems your chain adjustment is not proper.
So lose the chain one step or put the next buckle, observe if the flapper is still up or seal properly.
If so, then the chain is the main problem, and your problem is solved. If no, then check another matter.
2. Toilet Flapper Won’t Drop because the new Flapper is too light.
Suppose your flapper will not drop because of the flapper itself. Yes. Flapper gets down by gravity, and a few amounts of water remain after a flush; by the gravity force, the flapper seal down.
Toilet flapper does not generally break down, but low-quality flapper may and causes the flapper to be lightweight against the water.
Another reason the flapper is new and not heavy as required is so it does not sit.
Is this the reason in your case? Does one think to push yourself the flapper and then observe if it still floating, then the weight is the problem you need to replace it?
3. Another reason the flapper is not Closing -The flapper is New & the Size is not correct.
Install a new flapper super easy, but the size is vital for fits. Above all, reasons are not under your case, and then size can be the problem.
The flapper seals the flush valve to hold the water and opens when required; just push the handle water down.
If the size is not correct as of the gasket, then it may be the problem flapper not closing. It does not close properly if it is small; similarly, it does not close correctly if it is relatively large.
So check this point.
4. Toilet Flapper won’t close because of the Air Pressure.
Air pressure is a significant cause for a flapper not being close. The air present in the duct that can not move out then create pressure in the upward direction. This leads to a flapper not being close.
5. Why does the toilet flapper stay open – Because of Mineral build-up
Prolong mineral build-up accumulate beneath the flapper seal and forms a thick tier which is the cause for not closing the flapper and staying up all time.
This is usually happening in old toilets.
6. Another cause Why is my toilet flapper not closing?
Flapper Hinge- A flapper hinge or flapper’s arm is attached to the overflow tube with small arms, which holds the flapper during the flush.
If the flapper’s arms are not flexible or lubricated, then it is stuck tightly to the flapper.
