My Buying Guides on American Standard 738109-0070a Flush Valve Assembly
What I Looked for Before Buying
When I started looking for the American Standard 738109-0070a Flush Valve Assembly, my first concern was compatibility. I made sure it matched my toilet model before anything else, because even a small mismatch can cause leaks or poor flushing. I also checked whether the assembly included the parts I needed, so I would not end up buying extra components later.
Why I Considered This Model
I chose to focus on this flush valve assembly because it is designed as a replacement part for American Standard toilets, which gave me confidence in the fit and performance. I wanted something that could restore strong flushing without requiring a full toilet replacement, and this part seemed like a practical solution.
Compatibility Matters Most
The biggest thing I learned was that compatibility is everything. I compared the part number carefully and reviewed my toilet’s model information. If I were buying again, I would still double-check the tank shape, mounting style, and seal requirements. That saved me from making a costly mistake.
Build Quality and Durability
I paid attention to the material quality because a flush valve assembly has to handle repeated use and constant water exposure. I looked for signs of sturdy construction and reliable sealing surfaces. In my experience, a well-made assembly helps prevent leaks and reduces the need for frequent repairs.
Ease of Installation

A straightforward installation process matters to me because it saves time and keeps the repair affordable. If you are like me, you will want clear instructions and a design that fits securely the first time.
Performance I Expected
My main goal was to improve flushing performance. I wanted the toilet to flush smoothly, hold water properly, and stop running after each flush. A good flush valve assembly should help restore that balance, and that was one of the key reasons I gave this part serious attention.
Price vs. Value
I did not just look at the price tag. I compared the cost against how much value I would get from a proper repair. For me, spending a little more on the correct replacement part made more sense than dealing with repeated leaks or weak flushing. I always think long-term value is more important than the cheapest option.
What I Recommend Checking Before Purchase
Before buying, I recommend that you:
- Confirm the exact part number
- Verify toilet model compatibility
- Check whether the seal or gasket is included
- Review installation requirements
- Compare seller reputation and return policy
