The M&F 90mm 90° bended heavy duty tank overflow outlets are ideal for flat wall tanks (especially poly tanks).

The FLANGED outlet (pictured right) has three pre-moulded holes for fixing and when installed will add 120mm of water to the tank before overflowing. This increases the volume of water that can be captured in the tank and stored for use.

The PLAIN outlet (pictured left) is the only lead free M&F adaptor available in Australia. Ideal for a variety of applications. 

To fit tank outlets, simply rivet or screw on to the tank wall. If using screws drill a hole in the fitting first. Rain Harvesting’s Mozzie Stoppa™ Flap Valves and Screens can fit directly into these outlets to insect proof the tank.

90° Bend High Level Flanged Tank Overflow Outlet 100mm Now Available.

The "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.
