For example, if your faucet was made in 2010 it is a 400 Series faucet. Another way to identify the series of faucet you have is by the handle turns. On the 400 series stems the handle will turn 180 degrees. Therefore to turn on the faucet the handle will turn half of a full rotation. The 400, and 500 series faucets are often mistaken for each other. The faucets, and the stems will look identical. The only difference being the thread pitch at the end of the stem, which means a 400 series stem cannot thread into a 500 series faucet, and a 500 series stem cannot thread into a 400 series faucet.
