Excellent Product
I have two bathrooms and both of the flush valves suffered from the same issue. They would not stop running. I received a replacement for one of them under warranty and the replacement was one of this model. It worked perfectly so I decided to order TWO more of the exact same model. One in a spare and the other was installed in my second bath room. Could not be happier with the installation, and performance. I am 78 and the toilets are not easy to get to. But the installation was so simple that even I could do it.

Fixes that ghost toilet
We have three American Standard toilets and all had issues with water continuously running. I was going to bite the bullet and call a plumber when youtube came to the rescue. Watched a 10-min video, identified our toilets as being American Standard, and ordered these parts. Shipping was fast and install a breeze and success; no more running toilets. Life span is from 2-3 years so I purchased a few as spares.

Easy to use. Worth the money.
Had to replace the toilet valves in my fathers home sine the others were old and worn and the hard water there doesn’t help the situation. They were easy to install and work great.
