A water level control device has connected tubular housings, one serving as a support for a hose connection and the other serving to support a valve housing assembly for operation of a toggle valve within the valve housing. An airtight float serves to raise the one extreme of a float rod when buoyed by sufficient water level admitted through apertures in the valve housing. The other extreme of the float rod is attached to a rod holder to hold the float rod. The rod holder passes through an outlet apertured valve seat wherein a valve washer attached to the rod holder within the toggle valve cavity is urged against the outlet valve seat by water pressure from a water hose.
