3. FLOATING INTAKE // 4. OVERFLOW
A rainwater system designed with WISY products requires minimal maintenance and never needs replacing.
With a WISY filter, you'll never clean your tank again.

Floating Filters
The third step in the WISY 4-Step System is the floating filter, which draws water in to the pump from below the surface level to avoiding taking in any small particulate that may be floating.
COARSE FLOATING FILTERS
Since all harvested rainwater is filtered before entering the tank, the floating filter should never clog but will instead take water from just below the surface. Water at this depth is of the highest quality in the tank, because any particulate that enters the tank either floats on the surface or settles to the bottom. In RMS- designed systems, the floating filter acts more as an uptake point for the pump than a filter; thus, the floating filter should never require maintenance.
The floating filter consists of a polyethylene ball and stainless steel filter and is supplied with a standard 7 ft. length of food-grade suction hose. The nozzle connections are available in 1, 1 1/4" and 2" sizes. The filter is available separately or as part of a kit for both submersible and booster pumps.
Filter mesh size: 1.2mm (1,200 microns)
OPTIONS: With or without 7 feet of food-grade suction hose.
