Please Diagnose Toilet Flapper Problem

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 handle.
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.
Possibilities: * 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. Replace it.
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 far.

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.

Damn, you got good eyes. I can't see the bottom of the flapper on mine.

If this is a new flapper, the most common problem is the chain hanging into the flush seat. Shorten the chain (or adjust handle) to where there is a slight amount of slack when flapper seals.

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 have 25 of these buggars in my facility and if you have a bent handle or twisted handle adjuster...it will happen. Or there can be just enough slack to hook or catch the flapper from dropping.

if the chain is set a little short this can occur, try making it a tad longer, by moving the hook

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.
