CARTRIDGE IDENTIFICATION
Sometimes a customer will come into your establishment to replace an old cartridge. Unfortunately, it's not always easy to identify the model, especially if the valve has been discontinued – but using a little detective work, it might be possible.
Recently, a local dealer called our sales person Rob looking for help to identify the cartridge on the left side of this picture. Luckily, Rob had this handy chart to help find the model number.
Apply what you learned: What is the model number of the cartridge he identified? (Hint: Rob already knew the cartridge on the right side of the picture was a 47 111 000 – the height of that cartridge helped identify the cartridge on the left.)
