Rated 4.3 out of 5 by 32 reviewers.
Rated 1 out of 5 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 out of 5 by Easy to install - works great! An online video made this product very easy to install, and this valve works better than the old valve that it replaces. November 5, 2014
Rated 4 out of 5 by Stopped the leak!! Originally replaced just the seal, but it still leaked. Save yourself the time and trouble and spend the extra 15 bucks and replace the whole assembly should you suspect it's leaking. October 19, 2014
Rated 5 out of 5 by Champion 4 Flush Valve Replaced the vacuum clunky valve that came with my American Standard Toilet with this unit. So much better. The original was so noisy when valve dropped after vacuum was lost. Sometimes it wouldn't hold to lift valve up to flush and you would have to fiddle with it a few times to get it to work. This unit eliminates that problem completely.. Positive flush every time. This is the recommended replacement for the Champion 4 toilets. Be sure to order the recommended install kit with it. Not a good idea to try to use old seals over. Chances are they will leak. September 19, 2014
Rated 5 out of 5 by Perfect as a replacement Cost 30 dollars less than buying it at a discount plumbing supply and was exactly the same unit September 16, 2014
