La pompe de mon réservoir de the toilette toto était brisé. It replaces the tsu25a without any problem.

Fast delivery and easy do-it-yourself replacement. No issues whatsoever. My usual inclination when something is not working properly is to replace it. When parts are needed, they aren't readily available at most hardware stores.

The valve was delivered on time and was easily installed in about 15 minutes. The installation takes roughly 8 minutes, including the clean up of the tank. Arrived in two days, so superior to the * knock offs at the local big box.

I replace it, but it still leaking. Worked less than a year and is now hissing and running water. Uninstalling and re-installing the defective product all over again, takes a long time and seems worthless.
