Filtering

The rainwater from the roof generally should be filtered with a fine filter before entering the storage tank ( < 0.2mm or 0.008 inches). For non-potable uses there is no need for additional filtering either on the suction or pressure side of the pump. The reduction in flow resistance will enhance the longevity of the pump. Additional filters can develop into an area which will promote the growth of bacteria on the filter insert.

The simple but high precision WISY filters use surface tension (adhesion) in conjunction with a fine stainless steel filter mesh which excludes unwelcome debris. By this process about 90% of the rainwater is captured, filtered and diverted into a storage tank, while the remaining water carrying leaves and other debris is redirected into the sewer or soakaway.
