Abstract: A system of filtering runoff water from a roof cleaning is used to remove contaminants from water that has been used for rooftop cleaning. The system is also configured to gather water noninvasively from downspouts or topographically low points upon the roof. The system of filtering runoff water from a roof cleaning utilizes a pump that is connected to a large bin for filtration. The pump is placed at a low point upon the rooftop, thus enabling optimal water collection for subsequent pumping. The bin contains a disposable filter through which pumped water may pass, either through force from the pump pressure or due to the effects of gravity. Clean water is then ejected from the bin, or otherwise guided to an appropriate drainage area. This arrangement allows for easy maintenance, as a rooftop cleaner need only to swap out the old filter for a new one after cleaning.

Abstract: A rain water vessel (1) includes a water inlet (21), a main tank (26), a dump tank (27) inside the main tank, and a diverter valve (31, 32). The diverter valve (31, 32) is, after a period without rainfall of less than 1 hour, normally in a first condition in which it directs rain water entering the inlet (21) into the dump tank (27). A float (33) is operated when the dump tank is filled with water to a predetermined amount, to cause the diverter valve to be put in a second condition in which it causes the rain water to flow to the main tank (26). A drain (34, 36) lowers the amount of water in the dump tank over a period of time in excess of 1 minute by outflow to exterior of the vessel (1).

Abstract: An irrigation system includes one or more valve assemblies which are connected in series to a pressurized source of water. Each valve assembly includes a cylindrical housing, a ball valve, an inlet and two outlets with one outlet generally opposite from the inlet in a lower portion of the housing. The other outlet is disposed in an upper portion of the housing and adapted to direct water to an area of ground for irrigation. A pit and float are associated with each valve assembly and arranged so that some of the irrigation water will flow into the pit and raise the float. The float is connected to spring biasing means and when the float reaches a predetermined level, the ball valve will spring upwardly to close the upper outlet and redirect the water to another assembly. Water pressure will then maintain the valve in that position.

Abstract: A downspout baffle mechanism is disclosed, adapted for use in conventional, vertically disposed downspouts for diverting controlled amounts of water descending in such downspouts to water collecting means located above and spaced from the normal downspout terminus. The baffle mechanism is controlled by the rise and fall of a suitable float in the water collecting means through a motion reversing mechanism such that the baffle diverts water through a side opening in the down position of the float and substantially seals such side opening in the up position of the float. The baffle and control mechanism is preferably incorporated in a preformed assemblage adapted for insertion in a conventional downspout by merely removing, at the desired elevation, an appropriate length of the downspout.
