Abstract
A fail-safe water saving shower enclosure system includes a showerhead, shower faucet, power adapter, an active infrared sensor, electromagnetic activated fluid valve and shower walls. The infrared sensor installed on one shower wall aims at the opposite shower wall that has the showerhead. The enclosure is electronically partitioned into a restrictive flow zone and free flow zones. When a bather is not present within the restrictive flow zone, the showerhead flows at a free flow rate set at the shower faucet. When the bather does not need water, he simply moves towards the restrictive flow zone. The sensor signals the normally open electromagnetic valve to shut off water from reaching the showerhead. The free flow of water resumes when the bather moves towards the showerhead. The showerhead always receives a full flow of water without the presence of a bather, despite a failure of the disclosed components or power loss.
