Abstract: The remotely activated fluid control system prevents damage from leaking fluids (such as water or gas) escaping from damaged pipes by providing a user-activated controlling device that allows the user to activate a remote inline first shut-off valve in the main fluid supply line, such as when leaving the building. An integrated shut-off delay function delays the fluid shut off a preset amount of time to accommodate a currently running appliance, such as a dishwasher that needs to draw water to finish its cycle. An optional function is provided that allows a residual fluid flow to accommodate appliances that use a minimal flow to maintain normal operation. Optionally, a display control panel is provided to display system data from a flow measuring device and water temperature sensors. Optionally, a single engagement of the user-activated controlling device may restrict the fluid flow in one or multiple flow interface systems.
