Review on 🚽 American Standard 738920-0070A 3-Inch White Flapper Assembly, Ideal for Toilet Repairs, 3 in by Eric Smalley

I accidentally bought this valve to fix a leaking American Standard Cadet 3 with a 3" flush valve. You might think that since American Standard sells both toilets and their parts, an American Standard toilet would use American Standard replacement parts, but you are wrong. Apparently my American Standard Cadet has universal Fluidmaster components inside and the two dampers are NOT INTERCHANGEABLE. When you go to American Standard's website, you are prompted to look at the cap color. If you have a white flap, buy a replacement white flap (this one). If you have a red damper, buy a red damper (FluidMaster). There may be other combinations, but the moral of this story is to buy a specific model with a valve rather than buying something for the Cadet toilet, since American Standard has used different, non-interchangeable components in the same model of toilet in different years. I needed this one. The main difference between US 738920-0070A and Fluid Master 5403 is that the mounting tabs on the Fluid Master flush valve are TOO SHORT to fit US 738920-0070A. In addition, the inner diameter of the silicone seal on the 738920-0070A is significantly larger than on the Fluid Master 5403.Pro. Tip: You may only find flush valve seals. These new 3 inch dampers feature a durable plastic base that is unlikely to crack or warp. The part that usually needs to be replaced is just the valve seal, which is basically a silicone ring.
