0voteA: Those are some very common questions that we get. The flush valve volume (gallons per flush) cannot be adjusted. However it can be changed by replacing the diaphragm kit.The diaphragm GPF needs to match with the GPF of the porcelain to function properly. You can determine the gallons per flush of your valve in a couple different ways. If it is a newer valve it will have a white sticker on the underside of the valve body by the tailpiece, the sticker will have the GPF written on it. If there is not a white sticker on the valve then you can look on your porcelain fixture to see if there is a GPF stamped there, this is typically located where the brand name is.
