About 50% of the time, the flapper seats properly after flushing. The
rest of the time, it does not, and it's necessary to tap the flush
Is this a flapper problem per se, or a problem with some other part of
the mechanism? Thanks
The fix to this is truly trial and error.
* The seat is covered with water deposits.
Scrub gently with a low-abrasive scotch-brite cloth or steel wool.
Possibly apply vinegar. Don't make scratches in the surface, or you'll
have a permanent leak.
* The seat is damaged.
Replace the seat.
* The flapper is misaligned above the seat.
Align it properly.
* The flapper is damaged or worn.
Start by replacing the flapper. It's less than three dollars most
places, and it takes about 30 seconds.
If the bolts that hold the tank to the base are corroded, get a rebuild
kit and replace the whole works all at once. You'll be set for ten
years or more. If the seat is damaged, this is the way to go.
I had just replaced my flapper when the same problem started occuring.
It took a while but I found that the flapper was wedging itself on the
bowl fill tube. a tie wrap placed on the fill tube stopped this. At
least part of the problem was people rotating the flush handle too
Check pull chain for proper alignment and that it doesn't hang up on
anything. Check flapper for tears/damage, etc.
Flappers are generally about the cheapest/easiest replacement part in the
toilet so next time you're by Home Depot, pick one up and change it out. It
will about two minutes, even if you're all thumbs.
Only exception is that some older OEM flapper assemblies are integral with
the flush valve refill tube and if that's the case, you'd need to replace
the whole flush valve assembly-- a bigger job but still easily doable by the
average DIY guy.
Prolly the flapper hinge has too much play (worn out) and the flapper
falls all over the place instead of on the hole. Tighten the hinge with
a larger pin or bend the pin struts in a little or replace the whole thing.
I've never encountered a chain misadjusted so far that it can create a
loop that hangs down far enough to get between the flapper and its seat.
But, I have experienced chains which once in a while manage to get a
link or two "folded over" and snagged which shortens it enough to keep
the flapper from dropping onto the seat.
I've heard a good solution for that kind of "chain kink" problem is to
replace the chain with a piece of nylon fishing line tied off to the
correct length, but I've never bothered trying that.

I assume that you have already put a new flapper on and 50%
success rate is what you have now. That is because all flappers are
not created equally. Many generic flappers that are used for repair
are cheap and being so their dimensions vary enough to cause this
type of problem. Try to get the OEM part or at least purchase a
higher grade universal flapper that may have better dimensions.
Changed my SIL's the other day. The one I took out had a round blue flat
vinyl washer/seal that had gotten hard over time. Everything was still good
with no scars or dings, just got hard. Changed it with one of the kits, and
it had a rubber (or looks rubber) flapper, and that did it. See if yours is
gotten hard. Trouble is, you gotta pull it to really examine it.
