<p>A drain valve cup (2) is screwed into a valve lower part (3) having a suitable internal thread. The valve lower part is then aligned precisely with a connector (4) for an eccentric link rod, perpendicular to the mounting wall and then fixed in this position. A seal is formed by screwing in the drain cup from the top into the valve lower part. Independent claims are included for a mounting tool, and a mounting gauge.</p> |
