Rain Harvesting Tank Overflow outlets


Complete range of overflow outlets

Rain Harvesting has a complete range of tank outlets available for flat wall and corrugated tanks including 50mm, 80mm, 90mm diameter fittings.

90 degree bend Outlets

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.
