Eljer-Valley pressure balance shower faucet

[Reader Review]

Bought this place and with the 1st shower the shower faucet will not completely shut the water off. I see a nylon cross that might turn to adjust the worn washer that is most likely leaking.

Assume that I need to back off the first chrome collar that appears to screw on to the base mount where the hot and cold lines meet.
Not wanting to break it trying. I wanted to confirm this removal is correct

This is to a Valley shower faucet circa 2000
Looking for a rebuild kit to replace worn rubber gaskets inside . Advise is welcome

Thanks Ken

Your valve is the pressure balance. This was sold through Valley and Eljer under the U.S.Brass parent co.
