Abstract: This invention completely mitigates the problem of water dripping out of a conventional shower head over a long period of time, and/or suddenly discharging from the shower head, long after the shutoff valve is closed. The invention is very simple and consists of drilling a small hole in the body of the shower head, and providing a flapper with a hinge on one side of the snall hole and a stopper on the other side. After the shutoff valve is closed, gravity and partial vacuum inside the shower head opens the hole, thereby destroying the partial vacuum and ensuring that residual water in the body of the shower head gets discharged immediately. When the shutoff valve is opened, water under high pressure ensures the flapper firmly closes the small hole, thereby preventing water from escaping through it.
