    ok flush valve
  

*by R***H on Reviewed in the United States on May 16, 2023*

It works, but leaks water all of the time

    Huge improvement over the original flapper valve
  

*by G***L on Reviewed in the United States on June 3, 2022*

I replaced the flapper valve with the OEM American Standard part twice, and both times I again had a slow drip into the bowl over time causing phantom flushing.  It's a terrible design, and I'm sure wastes more water in the long run than any savings the OEM part supposedly provides.  The NuFlush valve, on the other hand, is a much more intelligent design.  I installed it very easily and right away it's obvious that the flush power is stronger and the mechanics of this valve I believe will last much longer.  I was at first concerned that the tank to bowl bolts were plastic, but they actually seem to be holding very nicely, and perhaps won't corrode like the old metal ones do.  So far, I am very pleased with this NuFlush valve and would encourage anyone with a Champion 4 to use this instead of the American Standard flush valve.  BTW the instructions are not well written, but it's easy enough to figure out.

    Convert your American Standard Champion to this flush system.
  

*by T***A on Reviewed in the United States on August 29, 2021*

The American Standard Champion 4 has two serious problems. One is the phantom flushing where water leaks around the flush seal.  This is happens after several years of the seal absorbing water. The other problem is poor flushing trying to use only 1.6 gallon (6 liter) which ends up requiring two flushes to be effective.  This design was an unsuccessful attempt to meet a California government regulation caused by poor water supply planning.The NuFlush conversion has completely eliminated both of these problems that I had been fighting for years.  It adds slightly more water and uses a demonstrated flap flush valve that works correctly.CAUTION - My American Standard tank 4266 CANNOT use the aftermarket tank-to-bowl 4 inch gasket. It was too thick and caused the tank to be loose. The original AS seal can be re-used between the tank and the bowl.I called the NuFlush supplier with excellent results.  He answered all my questions in person about the gasket for my tank. Very pleased with this purchase.
