Abstract
A fitting is disclosed for covering the vacuum orifice formed in the wall of the swimming pool. The fitting includes a hollow body member connectable to the vacuum orifice and having an opening for receiving a vacuum hose. A spring loaded cap is connected to the body member and is designed to seal the orifice when the cap is in the closed position. A safety locking mechanism is provided to prevent the inadvertent opening of the fitting. In the preferred embodiment, the cap further includes a lug for engaging a vacuum hose to enhance the connection between the hose and the fitting.
