My toilet has discontinued Korky flapper, which is designed with a plastic ring that clips to the bottom of the flapper's air cavity. Today, this plastic ring separated and is now resting at the bottom of the toilet inside the siphon jet, which is causing the toilet to not flush properly (no siphoning power, i.e. whooshing).
The ring is too large to pull through the siphon jet hole, though the plastic is malleable. I've been trying to break the ring, and to force it through the hole with no luck. I think I might need to try to melt the ring with a soldering iron, but only after I've pumped out all the standing water.
What other techniques or tools are available to help remove obstructions in the siphon jet?
