Abstract: The invention relates to an automatic soak watering system comprising a main water supply line (10), a valve (VI); a tightly closed tank (20) with an upper pipe connector (21) and a lower pipe connector (22); pipelines; and a water supply set including: a spring check valve (V2), a one-way valve (V4); and a tray (30) having a control point (31) higher than a water receiving point (32); and an automatic controller (38) controlling a three-way valve (V3) on the basis of the water level in the tray (30) at the control point (31). The invention also relates to a self-actuated three-way valve to replace the three-way valve and the controller in the automatic soak system.
