Toto toilet leaking and how to fix




This has been happening for a while. I wasn’t expecting to have to replace a flapper for a new Toto toilet so soon. The original flapper has a design flaw.


The edges of the pink flapper actually bends since it is made out of soft rubber. So over time, it slides outwards and pulls the flapper off the hole. The fix is to push the sides in, but after some time, the flap is off the hole again. The flapper is soft because it actually has holes that you need to wiggle over the arm or handles of the overflow pipe.



I’ve been putting off this repair because I thought I had to buy another flapper that has holes in it like this one. All replacement flappers just have a half arc that you clip onto the handles.

Turns out I didn’t need to.








If you look at the replacement, it has a half arc and it just clips on. To remove the pink flapper, since it is rubber and flexible, you can just wiggle it off the handle even though it has a L shape at the end.

The net result is that the new flapper works way better. I took the opportunity to adjust the chain on the handle too.

The new handle’s arms are plastic and stiff. So it should not pull the flapper away from the hole over time. A rubber flapper with rubber handles is just asking for trouble. Given the reputation of Toto, I wonder why they included such a poor flapper to begin with?
