Question about American Standard AMERICAN STD 12 RGH Champion 4 Tank WHITE
Had a problem with water level dropping in tank causing toilet to refill a few times a day. The problem was the round rubber flapper had a few bumps along the sealing lip, I removed rubber seal and laid it flat on workbench and took a new razor blade to shave these 2 bumps off and as soon as the blade touched them they popped and water came out of them then they laid flat. Somehow they were water blisters in the rubber keeping the flapper from laying completely flat causing water to leak into bowl. It seemed fine and flexible otherwise so I reinstalled it and so far so good. I also feel better knowing I can just change this rubber ring as it pulls off of plastic plunger in case I need to change it. Hope this helps.

Testimonial: "Using the glue seems to be a good idea, but American Standard does not mention it. There was no glue on the original parts."
I assume that you are talking about the tank to bowl seal that is leaking--these do not require any kind of sealer. Inspect both mating faces to be sure there are no porcelain defects causing this problem. Take the water spigot/flapper seat out of the tank. If there is no gasket along the tank side, get some 'plumber's putty', make a rope of it, and wind it around the spigot just under the flapper seal area and reinstall it. There should be a rubber washer on the head of each attaching bolt (and the bolt head goes in the tank side) and the large sponge rubber 'o' ring that seals the water joint with the bowl. If the 'o' ring is cone shaped, put the wide end to the tank. If the tank is being used as a backrest by the user(s), you may need to hot-glue a wood backer behind the tank to prevent it from being pushed backwards.Don't pull the two bolts down excessively tight--just tight enough to eliminate obvious rocking.
