Why do I have to hold the handle down when I flush my toilet?

Answer 1

Another thing to check, is how the flapper is attached. Some flappers, come with a rubber circle,that can be cut off and discarded, and also lifting lugs, depending on the type toilet you have. If someone used both the rubber circle, and the lifting lugs to attach the flapper, this can cause the flapper to close too quickly. If the flapper is older than 6 months, go ahead and replace it, and make sure you adjust the chain, and cut off any excess chain, as this can get under the flapper. Good luck!

Answer 2

The chain/rubber strap that lifts the flapper when you push the handle is not adjusted properly. Remove the lid from the tank and see how much slack is in it. Adjust it so the flapper "just" seals. This will insure that the flapper opens all the way when flushed and stays open until the proper amount of water enters the bowl. You can turn off the water supply valve under the toilet and flush it to get most of the water out while you are adjusting the chain/strap.

Answer 3

I would guess one of two possibilities, either the chain to the flapper valve is too long, so the flapper valve is not lifted high enough to prevent it from closing during the flush, or you need a flapper valve with boyancy compensation so it doesn't close early.

Answer 4

Because the chain inside the toilet bowl water container is detached from the float. Open up the water container area of your toilet bowl (it's the rectangle "box" behind the seat) and check to see if anything is detached, then just either re-attach it or if it's broken (perhaps the chain is actually broken), just purchase a new one at Home Depot.

Answer 5

Your flapper valve is bad..
