<p>The water inlet and outlet branches for a hot water supply tank (7) are formed by two unions (4, 9) with concentric extensions at the point, where they pass through the side of the tank. The two unions are incorporated in a common body (1), the inlet (4) being at the top and followed by the inner tube. The outlet (9) below it is followed by an annular gap between this tube and a short tube (10) which is locked inside the body. This short tube projects inside the tank for a much shorter distance than does the inlet tube. This short tube carries a collar (13) which enables its outer end to be locked inside the bottom of the common body by a locking nut (6).</p> |
