I installed a new toilet about a week ago and am having one problem. If
I push the lever and release, often the flapper closes before the tank
is empty not letting enough water into the bowl to complete the flush.
I've tried adjusting the chain and flush lever but can't get past this
problem. It seems to me that if the flapper would raise just a little
higher, it would work, but the lever only allows so much vertical
movement. All help appreciated. Thank you
