If your inlet/overflow issue persists, remove your tank screen and check for floating debris on the water surface. Floating debris such as sworf from the tank installation process’ may be blocking the Mozzie Stoppa during overflow and drifting away from the overflow when overflow has stopped.
High or extra high tank overflows offer a simple and effective way to increase your tank’s storage capacity.
Whichever tank overflow product you choose to use, your overflow needs to sit below the base of your tank inlet screen. The advantage of the high level overflow is that it raises the maximum water level within the tank.
The diameter of the overflow must be equal to or larger than the diameter of the inlet pipe.
You can choose to use a gasket or silicon to seal your overflow to your tank. Silicon is not required if you use a gasket. All our tank overflow kits come with a gasket.

The bend on your high level tank overflow should face up towards the top of your tank in order to increase your tank’s storage volume and overflow height.
Yes. We recommend installing your high level overflow with the bend facing directly upwards, however, it can also be installed on an angle to adjust the upper level. This may be necessary to ensure the overflow level stays below the base of your tank inlet and/or tank inlet screen.
When connecting two tanks, it’s best to connect them at the base with a balance line. It is important to ensure that the tank receiving water from the roof or other catchment area has an overflow outlet.
Yes, it is important to mosquito-proof your tank outlet to keep mosquitoes and other pests out of your rainwater system. You can do this using a mosquito-proof tank outlet screen such as a Mozzie Stoppa Easy-Clean. All our tank overflow kits come with a mosquito-proof Mozzie Stoppa screen.
