I replaced a couple of them and destroyed those things. They're expensive, heavy, and they don't work well.

once every one or two years? How lucky! Mine leak almost as soon as they were replaced!

It’s not about the power of the flush, it’s a design defect in the OEM flush valve that causes the rubber seal on top to eventually start leaking and “ghost flushing” to happen. Since we had these aftermarket flush valves installed we have had NO issues.

@@samdavidowicz ... Agreed, but I'm talking about the function in a brand new unit. Saw the short flush feature written as a design feature somewhere, and for 3 years I have used that unit accordingly. If the flush valve is replaced with Newflush the water use can still be limited with an easy float adjustment; and the large oem flapper seal problem is avoided.

Truth is, I really don't care. Ever since I had this installed, my toilet works flawlessly.

@@samdavidowicz Good to know. Can you point me to someone who does?

You have to order it directly from NuFlush. At least that's what I did.

@@samdavidowicz Yeah, I looked it up. That would be OK. I also found the part number in one of the comments. Part number 28904.

Yes.

That would indeed be very helpful.

I think I found it: NuFlush Part Number 28904

Flush all the water in your Champion 4 Toilet.. kzfaq.info/get/bejne/f7pinMVi1Zi6lac.html

I have a champion 4 max with this same problem from day one. What Fluidmaster flush valve fits the champion?

You need a 4". I only saw up to 3" on Fluidmaster website.

They are ok with you stealing the parts from the stores but don't waste that dam water

They need to just sink into the ocean already

The problem is, "dud", the phantom flushing is going to waste more water than the Champion 4 system was supposed to correct. Instead of throwing more money at a new toilet, my suggestion is to install the Nuflush flapper in place of the Champion 4 system and then reduce the water level on the fill valve. I plan on doing this and will update.

Sorry to have ruffled your feathers; didn’t mean to. Sure, if you can’t afford to replace this defective toilet. The Champion is not a good toilet. A relative just installed one. Flush looks like a “B” at best (hold the handle down for a couple of seconds). Bowl wash “C+”. Most importantly, it started leaking within a week of install. She got notified automatically by the water company that she had a leak somewhere in her home. By the way, class action lawsuit now in California on this toilet. There are good toilets out there-Champion is just not one of them. Mentioned a good one in my previous post. Also, recently bought and installed a Niagara Stealth. Uses 0.8 gallons per flush. Good flush, mediocre bowl wash. Only $129 when on sale at Home Depot. (However, beware that it has potential issues unclogging if it ever gets clogged because of its design. Hasn’t clogged on us yet though.)

I originally had the predecessor to the Champion 4, which I believe was also called Champion, but the "new improved" 4 was supposed to correct a short flush issue. I remember American Standard sending the 4 to me for free. Anyway, with the plus or minus 4 inches water that always remains in the tank would, in my way of thinking, create a sediment-ladened liquid that would create more of a film on the edge of the Champion 4 flush valve edge, causing the leaking and phantom flushing. I'm just trying to make the best of a bad situation at this point. What I do like about the design of the Champion toilet is the canal in the bowl that creates a larger column of water in the bottom of the bowl instead of a small jet in previous bowl designs. I've always been the individual in the family that would stop up the toilet 😁, so the more forceful flush has served me well! Sorry for the name calling. I was having a bad day! ✌

Do you have to hold the handle down to get a full flush like I have to do on my AS Cadet?

@@jimrusch22: Funny, I actually own the “American Standard Cadet 3 FloWise Right Height 2-Piece 1.28 GPF Single Flush Elongated Toilet” in addition to the “American Standard Optum VorMax Complete Tall Height 2-piece 1.28 GPF Elongated Toilet”. Bought the Cadet about six months ago for a different bathroom. The Cadet 3 FloWise comes with an adjustable flapper. That flapper MUST be adjusted by the customer to get an adequate and useable flush. From the factory, the flapper is set to close as early as possible and use the least amount of water; however, at that setting, it might only work for #1’s. Turn off the inlet value, flush the toilet, remove the tank lid and place in a secure location, remove the flapper, make an adjustment, and try it again. Don’t remember at which setting I set my to, but now I get a decent flush without holding down the handle. Don’t just set it to the max water use because that will waste water. Getting the perfect setting might take a week or two with real world flushes. Keep the lid off and protected until the final and perfect adjustment is made. Why AS sets the flapper from the factory the way they do is nuts. I am sure customer service has tons of complaints and totally unnecessary.

Don't really care, because it's performed flawlessly ever since install. No more ghost flushes and the flushes are better on top of it.

The NuFlush will save water by eliminating ghost flushing. You can save water by adjusting the fill valve not the flush valve and get rid of the lousy American Standard flush valves.

I'm assuming the tank must be removed to install the Nuflush. If that is the case, it may work better but is no less work to install. Am I correct?

@@erichodnett338 Correct, the tank needs to be removed as part of the install.

It the manufacturer who has to comply to the regulations, they can only make it this way. @@SHJTMoises
