Update. I hooked up the air compressor and blew it out, going from
the shower head pipe to the tub and then to one sink. Blew out both
the hot and cold sides. Some dirty looking water did come out,
but no sign of any debris. Good news though is the flow rate is
at least double. ...

Probably scale/rust/sediment that at least is temporarily relocated if
not removed. If could manage to backflush _might_ do some good.

I've no klew on the specific fitting; don't recall ever heard the name
before even...
