In the installation, it lists cartridge# RP19804 and RP46074.
Which one is correct for my old model?
Thank you for your question. This trim kit includes an RP46074 cartridge for MultiChoice R10000 rough-in valves. If you have an existing pre-2006 1400 series valve, you can install this trim using the original RP19804 cartridge.
