I've got a standard American toilet with a tank above & behind the spot you sit on. Some time ago I replaced the flapper valve because its predecessor (made in two pieces) managed to drop the inner soft-rubber part into the drain hole. Ever since then, the toilet doesn't flush terribly well because that inner piece is partially blocking the flow.
Anyone have ideas for how to fish the thing out? I've felt around with my fingers and with an unbent wire hanger, nothing.
