Two of my toilets are of the same model. Both are made by American

Lowe's sells this flapper for around $9. Here, I need to pay more than
$30 for it.

About three months ago, one flapper would not come down after flushing.
I thoroughly cleaned it and then put it back. It started to leak. I
tried many things but ended up buying a new one.

Now, the other toilet has the exact same problem. Yesterday, I was
informed that the flapper would not come down. I went to check it. It
was not leaking at that time. I removed the flapper and cleaned it.
After I put it back, it started to leak, just like the other one. I used
a toothbrush and a plastic brush to clean. They should not damage the
flapper.

Can anyone explain why a flapper which was not leaking leaks after
cleaning? Much appreciated.



Maybe you did not ruin it...possible it was just deformed a bit and not
seated properly.
I don.t remember ever clng a flapper but tank seat for it. We have
pretty hard water. Flapper is made of pretty springy rubber like fish
fins. Rough handling it may render it no good. For slow leak check use
some dye drops.
