Similar to a previous question: Will my current mixing valve for the existing shower fixtures work with this new trim kit or do I absolutely NEED to use the one recommended by Delta (R10000-UNBXHF)?
Thank you for your question. If you have a pre-2006 1300/1400 series shower, you can use any 13/14 series trim, such as the T14467-SSH2O. However, you will need to use the existing cartridge rather than the one that comes with the kit.
Similarly, if you have at 1700 series shower, you update it with any 17 series trim by using the existing cartridge.
Units made after September 2006 (13/14, 17 or 17T series) will have a MultiChoice R10000 valve.
