Frequently Asked Questions
Q. "How do you replace the 'seal' on the older style Champion®4 flush valve?"
A. The following seal replacement directions are for the original Champion
®4 flush valve assembly #3175.002:
First, shut off the water supply to the toilet and flush the toilet to empty the water out of the tank. Disconnect the flush valve chain from the trip lever.
Lift up the flush valve cylinder and remove the old seal by pulling it out of the groove and sliding it over and up the cylinder. Install the new seal by sliding it down over the flush valve cylinder. Make sure it is seated into the groove.
Reattach the chain to the trip lever. Turn on your water supply. Check to make sure the seal is working correctly.
Q. "What is a bead setting and how do I adjust this?"
A.For flush valves with a float attached to the flapper chain, the "bead setting" refers to where on the chain the float is - in other words, the distance from the top of the flapper to the float. This controls
how much water leaves the tank every time you flush the toilet. The higher the float, the less water that leaves the tank.
To adjust the bead setting, you gently pull the float up or down the chain to the desired length. Sometimes
there is a plastic piece you will need to temporarily remove to move the float. Just re-attach this piece once the float is in the correct position.
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.
