Q. "I purchased the #738109-0070A flush valve. How do you properly install it?"
A. To install the #738109-0070A, use the flat disc (installation driver/flush valve wrench) included with the flush valve and place it inside the flush valve so the slots on the disc line up with the vertical ridges on the plastic insert inside the flush valve. Use a large screwdriver or a 3/8" socket extension and turn the disc counterclockwise to loosen the compression washer to the smallest diameter in order to place the flush valve into the hole in the bottom of the tank. Rotate the flush valve as needed to keep the fill valve rod or tank lever out of the way of the overflow tube. Now turn the flat disc clockwise to begin tightening the flush valve. As the flush valve is tightened the washer will begin to compress evenly on the inside of the tank hole. The flush valve may want to rotate from your set position so you will have to hold the overflow tube with one hand as you are tightening. Tighten until the flush valve is firmly in place. Remove the disc (installation driver) and install the flapper. Test for leaks.

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.
