I also have a PR-500 that requires a 10psi pressure drop instead of 3psi. Another reviewer writes that the manufacturer updated this model to 3psi in April 2020. Thus, it is evident that old and new stocks are being mixed up. It's crazy to use the same part number for both. It's great that it's now available in 3psi. This problem only needs to be solved with the part number. I will try to order again and dice again and hopefully get the 3 PSI version next time.
