Time-Lock Dual Stop

Toilet Fill valve for tank type toilet.
Ordinary fill valves operate with a single float system. Our Dual-Shutoff System shuts off with a common float & a safety switch using a mechanical timer that prevents the toilet from running constantly. Flushing causes the rotation of the timer, opening the safety switch to release the common float and allowing the tank to fill. The mechanical timer has then been activated with enough time to fill the tank to the correct level using the common float. At this point, the safety lock will close and will not allow water to flow continuously.
