It sounds like an unnecessary valve to me.


Completely unnecessary. Until the old valve fails. I've seen it happen and
I have one that does not shut off properly. I'm going to install a double
vale soon, but I have to shut off at the street to do it.

Had problems at my in-laws house and could not shut off the main. Sure wish
a second valve was there.

The plumber has probably seen many examples and that is why he did what he
did.
