Highly recommend for anyone who wants to replace their Toto flapper.

This is the legitimate toto flapper, just as advertised .... So easy to install, so simple to adjust for flush volume and so far working perfectly.

Broke down and bought Toto's original replacement part and it fit right and works fine.

*UPDATE*

Well about 8 months after I purchased this replacement it started to have the same problem the original one developed after two years or so, not forming a reliable seal, and letting water leak from the tank into the bowl. I am almost forced to conclude that it is a combination of design issues with the particular model I have and these flappers. I have another Toto toilet with a similar flapper that has given me no problems whatsoever. I only downgraded to 4 stars because it worked good for at least 6 months, which means the leak problem can be solved by a well designed flapper, and the fact that a similar flapper design works much better (longer) in another model toilet means that this flapper isn't all bad.

*ORIGINAL*

This flapper is less flexible than the one that came with my Toto originally. It seems to seal more reliably, and being somewhat heavier and less flexible I expect it to last longer. In addition there is at least one update to the chain - a small section of "pipe" that protects the lowest few links (closest to the flapper) from getting kinked or tangled, and preventing the flapper from closing entirely. In about a month of use the flapper has created a perfect (well as perfect as a toilet bowl flapper gets) seal on every flush.

What more can I say - it works just like it is supposed to and is not a cheap knockoff which will fail in a few months. It is a Toto replacement part.

What's to say about the product? Simply that it is the current factory part just sold here instead. Not generic, not knock-off, the real thing. It works great.

That it's eligible for Prime is all the better.

We ruined the old flapper because we didn't read the instructions and used a chlorine product in the tank. The flapper didn't seal properly anymore and we were leaking water. New flapper works great!

This model replaced the THU175S and the diameter of this model is larger than the THU175S with ribbed supports on top of the flapper. A much better seal than the THU175S and more ridged than the THU175S. The problem I was having with my old THU175S as the flapper rubber softened due to wear the far edge of the flapper would get sucked into the flush hole (due to the old flapper was barely covering the edge of the hole). I don't see this model having that problem due to the diameter allows for better overlap and the ribs (from center to edge) to strengthen the flapper. Now I understand why TOTO discontinued the THU175S. Sealed perfect the fist flush.

I also purchased these USED "LIKE NEW" and they were new in the package. Must have been returns from someone ordering the wrong part. Paid $13 rather than $19 for the exact same new product.

Hope these will last longer than the previous model. The older models would start leaking after a couple months. So far so good.
