Claim 17:
18. An external plumbing valve device, comprising:
an exterior structural portion and an interior structural portion, wherein the exterior and interior structural portions are disposed on opposing sides of a building wall structure;
the exterior structural portion, comprising:
a conduit body fabricated from chlorinated PVC, comprising:
an elongate shape having a hollow cavity therein; and
a horizontal conduit portion having a first end terminating at a proximal end of the conduit body and a second end terminating at a distal end of the conduit body, wherein the second end terminates into a vertical conduit portion of the conduit body;

a stem disposed within the hollow cavity in a manner parallel to the horizontal conduit portion of the conduit body and orthogonal to the vertical conduit portion of the conduit body, wherein the stem is fabricated from chlorinated PVC; and
a handle disposed at the proximal end of the conduit body, wherein the handle is coupled to the stem via a rotational leverage point allowing the handle to rotate about the rotational leverage point;

the interior structural portion, comprising:
a ball valve disposed at the distal end of the conduit body within the vertical conduit portion, wherein:
the ball valve is coupled to the handle via the stem and the rotational leverage point,
the stem is coupled to the ball valve via a coupling flange,
the handle, the rotational leverage point, the stem, the coupling flange and the ball valve all rotate together through a 90 degree rotational angle, and
the ball valve is fabricated from chlorinated PVC;

the ball valve rotates between a top portion seat and a bottom portion seat, wherein:
the top portion seat and the bottom portion seat each comprise a concave surface shape and are recessed into an inner surface of the conduit body adjacent the hollow cavity, and
both the top and bottom portion seat are corrosion-resistant and comprise a coefficient of friction value low enough to allow the ball valve to rotate therebetween; and

a first coupling mechanism disposed at a first end of the vertical conduit portion of the conduit body and a second coupling mechanism disposed at a second end of the vertical conduit portion of the conduit body.
