How to Fix Toilet Flushing Twice
Does your toilet flush twice with only one press of the toilet handle? With a simple adjustment of your toilet flapper, this is quickly resolved. If your toilet is flushing twice, it is most likely due to the fact that it is staying open too long and flushing too much water. If you have an adjustable flapper, this can be corrected by adjusting your toilet flapper to close quicker. If you do not have an adjustable flapper, your toilet may have the incorrect flapper installed. Additionally, please make sure the flapper chain is going as straight up and down as possible from the flush lever and has minimal slack. If the chain has excess slack or is too tight, the flapper may not perform adequately.

With an adjustable cone style flapper, this is accomplished by turning the dial on the flapper to open up larger holes - this will allow the flapper to closer quicker and avoid double flushes. If your flapper is not adjustable, you have an incorrect flapper for your tank and it needs to be replaced.
