What I Looked for in This Flush Valve Assembly
When I was considering the American Standard 738109-0070a Flush Valve Assembly, my first priority was compatibility. I wanted to make sure it would fit the toilet model I already had, because even a high-quality part is useless if it does not match the tank setup. I also paid attention to durability, since a flush valve is something I expect to handle repeated use without leaking or wearing out quickly.
Why I Considered This Model
I found this assembly appealing because it is designed as a replacement part for specific American Standard toilets. For me, that meant less guesswork and a better chance of getting a proper seal and reliable flush performance. I also liked that replacing the flush valve assembly can often solve common problems like weak flushing, running water, or leaks from the tank.
Compatibility Matters Most
Before buying, I made sure to check the exact toilet model number and compare it with the product listing. In my experience, this step is essential. I learned that flush valve assemblies are not universal, so I always verify whether the part is intended for my toilet series.

I always make sure I have the right tools ready before starting, because a smooth installation saves me both time and frustration.
Performance I Expect
For me, the main job of a flush valve assembly is simple: it should open properly during flushing and close tightly afterward. I expect it to help restore strong flushing power and stop water from continuously leaking into the bowl. When a part does this well, it can improve the toilet’s overall efficiency and reduce water waste.
Signs It May Be Time to Replace the Flush Valve
I usually consider replacement when I notice:
- Water running constantly or refilling too often
