I've been having the problem of having the chain from my toilet handle
getting caught underneath the flapper, thus preventing the flapper from
closing. A jiggle of the handle usually solves this, but I don't think
I should be having this problem.
When the flapper is closed, I have the chain adjusted so it is nearly
taut. When I press down the handle to flush and let go of the handle,
the handle immediately returns to its original position, therefore
creating a lot of slack in the chain which gets caught underneath the
open flapper. What's the solution to this chain problem?
