WISY 4-STEP SYSTEM

1. PRE-FILTRATION // 2. SMOOTHING INLET 
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. 


Before entering the tank for storage, rainwater should be both filtered and aerated.  Filtration removes large particulate matter, which frequently both carries and feeds bacteria.  Removal of this particulate matter, along with oxygenation of the water, greatly reduces the amount of harmful bacteria in the tank.  WISY pre-tank filters accomplish both of these tasks, protecting the water quality in the tank.
