Rated 4.3 out of 5 by 40 reviewers.
Rated 1.0 out of 5.0 by don't get a full flush new design uses less water because it sits 3 inches off the bottom of the tank so you have all that water that is not used in the flush. had to glue a 2 1/2 in piece of pipe on top so I could adjust the water level to get a better flush. am not at max water level and still don't always get a good flush. used to be a great toilet, now it's a piece of junk July 2, 2013

Rated 5.0 out of 5.0 by happy with new flush valve It only took one hour to finish including finding the right socket and all tools needed. Installed so easy and this flush valve seems way more durable. March 10, 2015
Rated 5.0 out of 5.0 by Replacement for old style Champion Purchased to replace an 8 year old Champion 4 flush valve that would not always activate the valve. New design is a better than the old one. Easy installation. Instructions are on-line. Would recommend purchasing the coupling kit. Works as good or better than when new. February 19, 2015
Rated 5.0 out of 5.0 by Works Fine The item installed easily and performed as expected. I would suggest purchasing all new rubber seals and install them with the new flush valve. It will save you the trouble of repeating the install . The valve has been in use for 2 months now and gives a complete flush each time everytime. February 7, 2015
Rated 1.0 out of 5.0 by champion flush valve assembly The valve was easy to install even though the installation instructions were for a different type of flush valve. the reason I was replacing this valve is because the original valve was leaking down and a new seal ($5.95) did not fix the problem. Upon completion I filled the tank and it still leaked down. The leak was not around the bottom seal because it only leaked down to the top of the valve assembly. I consulted with a plumber to verify that everything was done correctly on the installation. December 19, 2014

Rated 5.0 out of 5.0 by Nice update The install was quick and easy better than the original factory item. December 17, 2014
