Toilets, Sinks, Showers, Tubs and Disposals - Toilet water tank problem

Currently when I flush the toilet the rubber lip that covers the hole on the bottom of the water tank where water flows to the toilet bowl closes too quickly. Therefore, there is not enough water to flush down. How do I make sure that the rubber lip opens until the whole water in the tank empties before it closes?

Shorten the chain a little so the flapper is flipped to almost a vertical position when you flush it.

Thanks so much! I'll give that a try tonight.

I tried that suggestion and it didn't work; however, it leads me to the answer. By taking a closer look at the flapper, I found that the flapper has a bunch of numbers on it. By turning the dial to a the Max, I was able to solve the problem. The flapper now closes much slower than before.

Yes, you have one of the newer Oatey adjustable flappers. It is elliptical and twisting it will cause it to hold more of an air bubble. Great that you got it repaired!!

Again, thank you for responding. I have another toilet water tank in the house that does not have the rubber flapper. It has this white round plastic ring that goest up to release the water and down to stop the water flow. Any idea on how to adjust this version so that it closes a lot slower?

Anyone have any idea on solving this kind of toilet tank problem?

Sorry, let the post slip. The bell shaped flapper is not adjustable, and was not a very good design to begin with. Aside from removing the tank and replacing all the components there won't be much you can do. Don't despair, however, it is not all that difficult. Just make sure you buy all the components to rebuild the tank, and reserve a good 2 hours to do it. And, if you get stumped, let us know, we are usually prompt to answer, except when we have to go to work, and other silly things like that. Good luck with the toilet.

Most of the time the 1.6g toilets work good. Not sure how old your toilets are but remember, not all toilets are created equal. You would be better off buying from a plumber or plumbing supply house than buying the one on sale at home depot or lowes.
