    • Relief! Leaking valve fixed after many fails (w/ new 2019 addition too)
Size: 1 Count (Pack of 1)
Review Image by Tom Scott
OK, it is just a rubber disk but it solved my leaking American Standard old style one piece! I had bought three different whole valves --each with rubber disks that LOOKED like this but they all leaked, some a little, some a lot. I bought the red ones at the big box "HD" store. They leaked too. After a frustrating week of sealants and repeated swapping of parts I bought this one. This was apparently an OEM item made by or for American Standard and it just snapped on and worked PERFECTLY. Five Stars! Later addition: A year later I had the same problem again with another of the three American Standard model 4s in my old house. This time I knew not to go to the big store and I ordered the same again one on Amazon. Yikes! It didn't work this time. Since it was the same "OEM" replacement that had worked last time I was sure it had to be another problem, maybe the seal underneath the bronze base? So I took everything apart and added a good seal of plumber's putty between the base and the porcelain. Nope. STILL didn't work; toilet refilled every 15 minutes or so. Carefully observing the new flapper and the old pivot it appeared that the edge of the rubber disk touched the pivot just enough to push it slightly off center. I thought of just clipping one edge, but since the disk can turn, i figured I'd get the same problem again if it turned a bit. So I took kitchen shears and trimmed about a sixteenth or an eighth inch all around. VOILA!!! It worked instantly. Whether it is no longer touching the pivot mount or by snipping away some of the circumferential stiffening I made it more flexible, in any case it makes a great seal now. Whew. I had almost gotten to the point of buying a new toilet. ... show more

This review is for a American Standard seat disc installed in a 1955 American Standard Champion 4 one-piece toilet. I tried a Fluidmaster 5103 seat disc. It worked, though it didn't last as long as I had hoped. I thought that the red rubber would be the longer-lasting chemical resistant variety but it only lasted three years. I bought this American Standard 033643-0070A seat disc at the same time just to compare the two. It fits fine and works right out of the box. Though the Amazon product information lists China as the country of origin, the package claims Mexico. I'm not sure if that makes any difference, or if American Standard has simply changed production to another source since my purchase. Also, as others have noted the reinforcing ribs don't extend to the outer edges of the disc as shown in the product picture. This doesn't seem to affect functionality. I look forward to seeing how this holds up over time. I expect better performance out of parts from the original equipment manufacturer. I have an American Standard actuator-style flush valve with the brass frame, not the plastic frame. I recently swapped out a Fluidmaster fill valve for a Korky. the Korky fill valve is much quieter and it includes a refill adjuster. It just works better. ... show more

    • A quick easy fix that is inexpensive and you can do it yourself!
Size: 1 Count (Pack of 1)
American Standard has made a toilet part that anyone can change in a matter of minutes. There is no need to call/hire a plumber it is a quick fix. My toilet would on occasion sound as if it was letting water into the toilet bowl without a flush. It did not happen on a regular basis and would last for only a second or two. I was told that on may occasions the flapper/flush valve gets old and looses its shape causing water to drain/leak into the toilet bowl. Sure enough I felt the valve and discovered it had lost its shape and was in terrible condition. I discovered this item fits my toilet/flapper and just snaps into place after the old one is removed. I just cut off the water drained the tank and changed the disc in a minute. I did not even have too take the flapper off (as indicated in the instructions). Saved the cost of a plumber! Finally something anyone can do with spending a fortune. ... show more

    • Seat Disc Review
Size: 1 Count (Pack of 1)
The seat disc totally met my expectations and was easy to install. A word to the wise--"One should always have a spare toilet seat disc available because you never know when the disc will begin to leak and it may take a week or two before a new one is delivered." I went to three different "big box" stores and two local hardware stores to purchase a replacement and none of the stores had--in stock--the proper size seat disc. I then ordered on-line through Amazon. ... show more

    • Perfect fit and seal, no more ghost flushes
Size: 1 Count (Pack of 1)
Finally after trying 3 other seat disk from different makers I found the answer. I was desperately.looking to replace my older style American Standard toilet (70s model) flush actuator seal. The old one was leaking and worn so I ordered 4 different ones from Amazon. The 3 after market ones were slightly smaller and didn’t seal properly lesson learned here I should have trusted my instincts and waited for this one. Upon arrival I installed it, filled the tank and perfect seal, no more ghost flushes. I actually just ordered another for the toilet up stairs. ... show more

    • Was the part that fixed leaking toilet
Size: 1 Count (Pack of 1)
On the advice of helpful forum and review posts, I decided to replace the disc with a new one hoping to stop a slow leak. The previous disc was less than 5yrs old and was an American Standard branded one. When I inspected it, it looked like what a 5yr old disc would look like, but didn't seem to be compromised in any way. I changed it thinking that if it didn't fix the problem, I would probably end up changing it out at some point anyways. To my surprise, just replacing this part with a new one solved my problem. Apparently as these discs age, the seal they form starts to deteriorate and leads to leaks. Anyways, it's worth a shot given it is low cost and may fix your problem too. ... show more
