ASC 32 Litre Stormwater Pit with ASC BPO-100EA Pump
The ASC 32 litre Stormwater pit and pump system is a ready to go pit for areas affected by stormwater. With a grated lid, the system is designed to be able to collect both surface water or from underground pipes and then pump away the excess water.Â
Common uses for the system include garage and driveways flooding, exterior edges of patios, around swimming pools, cellars and basements or in the backyard where you may have clay underground.
The ASC BPO-100EA has been designed for low flow applications where drainage is required. With a built in float switch, it will turn on and off automatically as the pit fills with water. Designed for clean water, the pump can be used for surface water, however will not pump sludgy water or debris.Â
