Thank you for your inquiry! When installing the Delta Integrated Rough-In Valve R22000 with a 3-setting diverter trim, only the top and left ports will be in use. If you are only using two ports, one for your shower head and one for your hand shower, you must plug the right port. If the left port was capped off instead, you can purchase just the 6 setting diverter cartridge, RP51919, so that all of your setting will work with your existing trim.
