Abstract
A waterline leak detection and shutoff system comprising an in-line flap valve which includes a pivotal valve flap member having attached thereto a magnet and first magnetically responsive switch which switches states, when the magnet is moved from a first position to a second position by forces exerted by flowing water, to activate a counter, and a second magnetically responsive switch which switches states, when the magnet is moved from the second position to the first position as the water ceases flowing, to reset the count of the counter. The counter continuously counts while the magnet is in the second position wherein if the count reaches a predetermined time limit an alarm means and/or an in-line shutoff valve are activated.
