What Customers Are Saying
The product has a mix of positive and negative feedback. While some users report the flush valve working as expected, many others experienced frequent leaks, "ghost flushes", and issues with installation and compatibility. The overall quality and durability of the product seem to be poor compared to the original factory-installed valve.

After 10 months it started to leak very slowly. Every couple of hours we would hear the water tank refilling because the water level had dropped too low. Now it happens more and more quickly and I have to look at a replacement - again.

No rubbers for the tank screws. They should come w
This was an exact replacement for the original valve. However, you have to remove the tank, and it did not come with new rubbers for the tank screws, or a rubber for the center flange. A little judicial use of red rtv automotive silicone sealed the screws, and outlet flange. The toilet works perfectly now. No more slowly leaking into the toilet bowl. The included plastic wrench was a very nice feature.

Poor Engineering
I have now purchased multiples of this unit. They don't last long before leaking. Does not seal either well or correctly. The big green seal does not fit well. Once it drops back down it always looks askance, slightly off. I would recommend purchasing a toilet that does not use this type of flush valve.

Exact replacement
I was unable to use this product on a Champion 4 1.6LPF. When I removed the tank to install the new assembly, I noticed a broken plastic diverter down inside the bowl portion of the toilet. I was unable to locate a replacement part for it, so we purchased a new toilet and returned the flush valve kit. The new Champion 4 we purchased has a similar diverter, but it is not plastic, it is an integral ceramic part of the bowl.

Am standard champion
Part delivered thru Lowe’s locker service was a returned part with missing pieces. I didn’t know this till my plumber opened the box to do my install. Very frustrated as my plumber had to go get parts to make do with my repair which increased my cost overall . Lowe’s should not put returned parts back into stock without a review. Parts were dirty and parts missing from who ever returned it.

Crappy OEM replacement parts
This is the second flush valve assembly that I bought and installed in my American Standard Champion 4 toilet. Both failed immediately after installation. I called American Standard consumer help line and was walked through several steps and checks none of which solved the problem. I then asked what I should do. I was advised to buy a new toilet. To say the least, I am very disappointed with the OEM replacement parts and will not buy another American Standard product again

These Valves Leak
It will not stop leaking. I went to see if there was something wrong with the seal and found out the seal is not replaceable on this model like the valve I replaced. The diameter of the seal is just large enough to cover the opening. If it lands a little off center it leak bad. If I physically place the seal on the opening, it leaks slowly. DO NOT PURCHASE. I was considering an aftermarket flushmaster valve but some reviews say it has the same issues. The original valve lasted at least 9 years. ...
