ABSTRACT:
A self actuating storm or flood pump used with septic tank sewage treatment facilities with leach beds and also used to pump excessive fluids from the lower floors of buildings such as flooded basements in dwellings. A tubular means extends in a vertical direction in said leach bed or from said floor and means are provided for fluid such as surronding water to seek its own level inside of the tubular means. A siphon hose having opposing ends extends from a lower portion of said tubular means up toward the upper portion of the tubular means and then outward from the tubular means to a disposal area. The outward end of the siphon hose terminates at a lower vertical point than the inner end of the siphon house. The inner end of the siphon hose communicates with the inside diameter of the tubular means so that excess fluid levels cause the fluid to flow through the siphon hose to the disposal area until the fluid level surrounding said tubular means reaches a level just below the inner end of the siphon hose. A removable top of the tubular means allows chlorine in solid or liquid form to be added to purify any water that is discharged.
