Curious if anyone knew the difference between these two diverter cartridges, or what the 'RP' might mean. Can't say I'm huge fan of the lack of info Symmons provides for their products.

Original diverters have worked fine for a long time
If I had to guess, it was done to so that they could make a diverter that would comply with the updated 2019 California plumbing code. The timing kind of makes sense, the it's outlined in code section 408.2.2, which no longer allows the use of shared diverters to serve multiple shower heads from a single valve. Symmons also made the valves around this same time and started selling them in 2020. I don't see an obvious way to reengineer the old spindle to work as a non shared diverter, and likely Symmons couldn't find a way either, so they updated the design, increased the bore diameter to allow for a cartridge that could comply with this change.They are a good co.
