    Hi Evans, The Champion 4" flush valve is designed for Champion 2pc toilets only due to its 4" size. The flush valve used 738138-0070A for your model has been discontinued for many years now through American Standard- but we do offer a universal flapper 7381129-0070A that would be compatible to be used with your original flush valve. Would you kindly reach out to our Consumer Connections team though our website https://www.americanstandard-us.com/ using the contact us form or live chat feature; live text from your cell phone or call us Mon-Fri 9am-6pmEST at 1-855-815-0004, thank you.

              does this seal eliminate the blister issues causing the ghost flush

              Answer This Question

              Hello Eric, Thank you for reaching out to American Standard. Despite continuous material optimization for hard water resistance, silicone seals remain susceptible to localized blistering under severe mineral conditions.

                Hello Eric, Thank you for reaching out to American Standard. No, it is not. The 4083 uses the 47387-0070A flush valve. It has been discontinued through us directly but they still carry them on chicagofaucetshoppe.com.

                  Works, but frustrating.
                  Purchased this yesterday to replace an aging flush valve on a 4 inch American Standard toilet. Install went smooth enough, but I had reservations about the change in flushing performance with the raised flush valve. Turns out I was correct. The original flush valve was located towards the bottom of the tank. Since this is a raised valve, it uses less water out of the tank (probably a water saving measure), but results in a less powerful flush. Ok, fine,.. I can deal with the less powerful flush, but the next day I’m dealing with so called ‘ghost’ flushes. Water is slowly leaking out of the tank requiring the tank to refill every 5 to 10 minutes. I’ve checked the seal, I’m not leaking out the base of the valve,.. everything is good. Now I’m annoyed. I knew this was common with these valves, but I needed a replacement and didn’t want to have to wait for shipping. Looks like I’m back to the drawing board.

                    Installed a few weeks ago, did the job it was intended to. Unfortunately I snapped the middle post of the original version of the flush valve that came with the toilet when trying to work out how to disconnect to put in a new seal... So off to Home Depot to get a replacement. This version is a little more cheaply made than the original and has a different method for replacing the seal but it was straightforward to uninstall the old, and install this new one. It comes with a plastic "wrench" to tighten the locking nut on the bottom of the tank which was helpful. I had trouble removing the old one ahead of the trip to the store (so I could make sure I was getting the right replacement). So worth putting the wrench somewhere you can find it again in a few years. It seems to have fixed the issue I was having with slow leak. Also the toilet is a champ at flushing.

                    Very simple to replace and last longer than traditional ones

                    There was nothing wrong with the flush valve although it was the wrong one for the American Standard toilet I had. HD description said it was the right replacement part but American Standard has changed the original part names and the part number for this valve isn’t the one they recommend for replacement. HD was excellent in the return process but it is important to note the one question they ask is whether the part had been installed in a toilet (my return didn’t). I assume if you try to put it in the toilet and it doesn’t work right they won’t take it back.
