WW1 Effluent Filter

Screens effluent in residential applications with flows up to 1,500 GPD (5.7 m³/day).

Features and Benefits

Zoeller Pump's WW1 Effluent Filter helps prolong the life of an onsite system by filtering solids which may cause harm to downstream components such as drain fields. Used in residential applications where the maximum flow is less than 1,500 gpd (5.7 m³/day), the WW1 filter includes a patented bypass protection sleeve to keep solids in the septic tank during cleaning. The deep pleated filter design offers highly effective filtering and solids retention. The filter is available with or without a 4” sanitary tee for easy installation in new or existing septic tanks.
