The downspout pre filter will require the screen to be completely wet before filtering rainwater and directing it to the rainwater tank or rain barrel. This will provide a first flush action, allowing all of the initial flow or rainwater to pass by the screen and divert away from the rainwater tank.
This filter should only be used with round downspouts or with a converter kit providing at least 20” of vertical round pipe above the filter. It can be installed in vertical metal or plastic downspouts.
If the filter is installed at the high water level of the rainwater tank or rain barrel, then the downspout filter provides overflow protection and diversion when the collection tank is full.
Filter insert requires cleaning a few times a year and its dishwasher safe.
