90° Bend Hi-Level Cistern Overflow Outlets

Add several inches of water inside the tank before the water overflows


 

Available to fit 3 inch and 4 inch schedule 40 PVC -

Aquabarrel sells Rain Harvesting's Tank Overflow Outlets for flat wall and corrugated tanks. Included is a screen that fits in line to insect proof the rainwater tank.

The High Level Flanged Tank Overflow Outlets are ideal for flat wall tanks (especially poly tanks) and will add several inches of water to the tank before overflowing.

The 4inch 90° Bend High Level Flanged Tank Overflow Outlet  "ripple geometry" comb allows the speed of the overflowing rainwater to be maximized. The combed circumference "breaks" the water surface and generates a higher outflow. Ideal for high rainfall events.

Note: The diameter of the overflow must be equal to or larger than the diameter of the inlet pipe.
