will this work with R11000 shower diverter
Thank you for your question, Johy! The Delta 14 Series Extension Kit RP77991 is designed for the newer MultiChoice Universal Rough-In R10000-UNBX valve, this kit is not compatible with the 3/6-Setting Diverter valve R11000. The RP75137 is the only available extension it for the diverter valve.
