<p>A sillcock intended to be mounted in a wall between a warm space and a cold space to provide a water flow passage through the wall comprises a water flow pipe extending between the warm side and the cold side of the wall, a shut-off valve including a valve seat and an associated valve body, a valve control member disposed on the cold side of the wall and a valve control rod disposed within the water flow pipe and connecting the valve control member with the valve. The valve seat of the shut-off valve is located within the water flow pipe at a point along the pipe, which has a lowest temperature exceeding 0 DEG C, when the sillcock is mounted in a wall, and preferably at a point located between the warm side of the wall and the location of the zero isotherm within the wall.</p> |
