Yorkville Series Toilet Repair Parts

Q. "Why does my toilet continue to run after flushing?"
A. If, after flushing, you find that the toilet continues to run, and you have discovered that by jiggling the handle it will stop; then the problem may be that the chain controlling the flapper is too long. When installing your flapper, you want the flapper chain's S-hook in the hole closest to the handle with very little slack in the chain itself. By doing so, when the toilet is flushed, the chain will fall behind the flapper where it won't snag and cause problems such as keeping the flapper from closing properly. Check to make sure that the flapper has enough clearance to close, i.e. not hitting the float ball when the water level drops. You also want to check to see that the toilet's flush handle (aka tank lever) is installed securely so it can't rotate too high, hitting the tank's lid or other parts and sticking.

Q. "Are all American Standard® parts 'standard' and are ALL their products and parts made in America?"
A. A number of their products are made overseas (as is the case with many other plumbing manufacturers as well). Please do not assume that all products made by American Standard (Am. Stan.) are made in the U.S. The word "standard" and "American Standard®" are NOT identical. Most of their faucet parts will only fit their brand (as is the case with their competitors as well). Many of their toilet parts will only fit their brand of toilet. Not all of American Standard® parts are universal ("standard"). We get this question frequently, and it is probably because some people assume that since they have the word "standard" as part of their name that they must be using parts that are "standard"; as in universally fitting. Just as car bumpers don't fit on all brands of cars, parts for "standard" toilets and faucets will generally not fit on other brands. Generally you must buy parts specifically made for (designed to fit) your specific brand of toilet/faucets, etc.
