When the pressure at the fluid delivery part(10b) of the fluid passage is higher than the designated pressure, a check valve(23) is open and part of water at the fluid delivery part(10b) flows thru the by-pass passage(14) to the discharge part(10d). Thus the water flow will not be disturbed by the water flow sensor switch. The standard pressure of the fluid at the water delivery part(10b) is adjustable to the desired pressure by turning around the by-pass pressure adjusting screw(23). And the water flow sensor switch is attached to a strainer(24) which is removable.
