ABSTRACT:
A method for removing water from a ponding area of a flat roof having a run-off system which is no longer operable to drain water from the ponding area which comprises directing a quantity of the run-off water flow in the run-off system as a result of the commencement of a rain condition or the like into a priming chamber from which run-off water is allowed to discharge into the run-off system at a rate less than the rate of flow of run-off water into the priming chamber and effecting a siphoning action as a result of the diminishing of the flow of run-off water in the run-off system as by the cessation of the rain condition so that the quantity of run-off water flowing into the priming chamber is less than the quantity flowing out thereby lowering the water level within the priming chamber and creating a suction action which is utilized to commence the movement of the water in the ponding area through the siphon device hose which movement continues until all of the water in the ponding area has been sucked up through the siphon hose.
