<p>A flow control device for the drain lines of a septic system interrupts the flow in the event the proximate water table rises to a level of over-saturation resulting in the effluent flow being directed to the remaining drain lines. Each drain line is provided with a control box having a float controlled inlet valve having an open position allowing flow to the drain line. When the drain line cannot handle the required flow rate or when the proximate water table rises, the float shifts the valve toward a closed position, thereby redirecting the flow to the remaining lines.</p> |
