Claim 18:
19. 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:
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 both the horizontal conduit portions and the termination point of the horizontal conduit portion into the vertical conduit portion of the conduit body, wherein:
the stem is disposed parallel to the horizontal conduit portion of the conduit body and orthogonal to the vertical conduit portion of the conduit body, and
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.
