WISY Garden Rainwater Filter Collector

Filters rainwater up to 1,100 sq. ft.

The WISY garden rainwater collector connects to a single vertical rainwater downspout and can filter precipitation from a roof area up to 1,000 square feet for irrigation, car washing or other non-potable uses. The filter is installed above-grade in the vertical rainwater downpiping to direct debris to the stormwater system and divert clean rainwater to the storage tank or rain barrel. The filter also acts as a first flush device. 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.

The WISY garden filter collector can be installed in vertical metal or plastic downspouts. The garden filter provides overflow protection and diversion when the collection tank is full. Housing and filter insert are made of stainless steel. Filter mesh size is 0.44 mm (440 microns). Filter insert requires cleaning a few times a year and is dishwasher safe.

Kit includes: mounting clip & screw, hose & tension ring, 2" x 3" or 3" x 4" downspout converter kit
