Frequently Asked Questions
Q. "What are the most commonly replaced toilet parts?"
A. This depends on several factors; each time you use your toilet the trip lever, flapper, and fill valve are operated. You will find,
however, that the flapper and fill valve are the parts most exposed to water and will be the first ones to wear out in most cases.
Q. "How are the lengths of the toilet fill valves measured?"
A. The toilet fill valve measurements we show are measured from the inside bottom
of the tank to the top of the fill valve. The threaded water supply shank that fits through the bottom of the tank is not included in this measurement.
Q. "How do you adjust the water flow of the Fill Valve for the Roma and Luxor toilets?"
A. To adjust the water flow of the Fill Valve you turn the volume control stem located next to the
plunger. Turn the stem clockwise to decrease water flow or counter-clockwise to increase water flow.
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.
