Question: what is the difference between a moen 1222 and 1225 cartridge?
Answer: The biggest difference between the Moen 1222 vs 1225 cartridges is how the shower valve handle turns the water on. Shower valves with the Moen 1225 cartridge are turned on by pulling the handle out and then adjusting the temperature by turning the handle to the left or right for hot or cold water.
