With Poly Tanks and Poly Products capacities and measurements are tested in accordance with AS4766, but may vary due to the roto-moulding process. Dimensions in metres are rounded to the nearest centimetre.

Subtract 100mm from pump cover dimensions when estimating internal measurements.

When estimating space requirements for siting your tank, Bushmans recommends a minimum clearance of 100mm at top and sides for Poly Tanks and 1m for Aqualine Tanks. Read less

100mm x 90Degree Overflow Assembly Kit

The Bushmans 100mm by 90-degree tank Overflow Outlet is designed to allow for the addition of extra overflow outlets. The overflows have a mesh screen that prevents mosquitos entering the tank and using the tank as a breeding ground. Flap screen valves can be fitted to outlets to further insect proof the rainwater tank.

The flanged Tank Overflow Outlet is designed for flat walled poly tanks and add approximately 120mm of water to the tank before overflowing.

The 90° Bend High Level Flanged Tank Overflow Outlet “ripple geometry” comb allows the speed of the overflowing rainwater to be maximised. 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.
