Unhappy Please Help - Water Get into Toilet Bowl When Flushing

Your help is highly appreciated in advance!!

After a plumber reinstalled the flush kit a few months ago, we run into this problem: everytime RIGHT after the flushing is done, the refill water THEN ALSO get into the toilet bowl, which is not supposed to! Usually, about 1.5 Gallon of water will get into the toilet bowl for every flush. After the flush sound stops, NO MORE water will leak into the toilet bowl. As a result, the refill process will take longer, and more water was wasted due to this problem.

Does anybody know what the problem(s) are for this issue? What need to be replaced to fix this problem?

yifangusa, Welcome to the DIY Forums.
It would appear that the flapper is not closing as soon as it should after the flush is complete. Flush it and watch the flapper. If it does not close as soon as all the water has exited the tank, change or adjust the flapper. Good luck.

Question Flapper Not Closing As Soon As Water is Flushed out

You are completely right. I observered it, and that's the case. The flapper is not closed until the tank is half-way refilled. Therefore, it wastes a lot of water every time when flushing. However, the flapper is brand new! Any ideas what I can do to have this fixed?

Again, your help is very appreciated!!

You may be able to adjust the chain. Give it "just enough" slack to allow the flapper to seat when in the closed position. Good luck.

Strange or not. I've tried to adjust the length of the chain many many times, and did just as you suggested. The length of the chain is just enough to have flapper to sit. However, the problems still goes on. Do you think there might be any other reasons?

I do not understand how the tank can fill half way with the flapper not seated. You may need a different type of flapper that will seat as soon as the flush is complete. Some have a little cup or sponge on the top. IF this is the type you had before replacement, this is the type you will need. Some toilets requier a specific type of flapper.

Some fill valves do waste water. Your 1.6 gallon toilet can use much more when flushing and filling. 1.6 gallons to flush and around .4 gallons or more as it fills back up. This water runs down the overflow tube via a small hose. I believe the purpose is to keep the holes in the rim clear. You might possibly lessen the amount available for the flush. Lower the water level until you have just enough to provide a proper flush. This will lessen the length of time the water is allowed to run.

Good luck with your project.
