Yea I order the manufacturer part from price pfister and it did not mate up to the faucet. The plumber that did the install modified the connection. Anyway after 7 years it was time fir an upgrade so I bought and installed a new one today.
Thanks for the reply though.
Trying to find who makes this diverter valve that was put on my price pfister model 26 marielle kitchne faucet. It appears the plumber did not use the original equipment during installation.
