Flapper Chain Problems
The chain connecting the toilet flapper to the flush handle is the source of many flushing problems. If the flapper chain is too long, the flapper won’t lift all the way & will drop too soon, resulting in an partial flush. If the chain is too short, on the other hand, the flapper lifts too high and doesn’t drop back into position. One has to adjust the chain manually to get the best outcome.
