4 Step Rainwater System – Wisy Downspout

WISY Downspout stainless prefilter connects to a single above ground vertical rainwater downspout and can filter rainwater from a roof area up to 1,600 sq. ft.

The Wisy Downspout stainless prefilter will require the screen to be completely wet before filtering rainwater and directing it to the rainwater tank or rain barrel. This will provide a first flush action, allowing all of the initial flow or rainwater to pass by the screen and divert away from the rainwater tank.

The WISY Smoothing Inlet and aerator is designed to add oxygen to the rainwater and prevent agitation of the biofilm on the rainwater tank(s) floor when additional water is collected.  Shop now!

The floating uptake floats on the surface with the intake point 4 – 6 inches below the surface of the water. This is where water is the highest quality in the tank, any particles have either floated to the surface or settled to the bottom.

Too much water and it wont stop raining? The WISY 4" Multifunction Overflow Device gathers and diverts excess rainwater to ground or drain.
