inlet 284 and outlet 286 are strapped or clamped to the upper downspout section 352 and lower downspout section 354 respectively using fastening clamps or straps 356 in combination with pliant wrappers 358 the pliant wrappers can embody rubber sheets or other equivalent materials however any prior art coupling means may optionally be used to couple the inlet and outlet of the system 280 to the upper and lower downspout sections as shown when water 360 enters the downspout assembly 280 via the inlet 284 and into the interior cavity 288 the water makes contact with the filter 20 as previously discussed debris and other solids carried by the water 360 are then trapped by the filter 20 along the upper surface 22 of the filter the solids and the debris are then pushed by the stream of incoming water and incoming solids and or by gravity and fall into the collection container 292 water however passes through the filter 20 to the underside 24 of the filter in the direction of the main deflector plate 332 during normal flow water flows in a downward direction towards the outlet container 294 where it is then cleaned or scrubbed by the media pads 298 a 298 b before being deflected again by the exit flow deflector 324 the exit flow deflector 324 channels the water over the final filter media 308 where it is further cleaned or scrubbed before existing the housing 292 via the outlet 286 as readily apparent the media pads 298 a 298 b.
