These male and female tank overflows can be easily installed into a wide range of overflows and mosquito proof screens. They are also UV stablised and AS4020 compliant.
The 90° bend allows you to drop your overflow pipe straight down and flush to your rainwater tank – for 100mm overflows, no “kick” with the standard 88° bend (standard 100mm bends are not available in 90°). Overflow pipework will look aesthetically pleasing.
Tank Overflows provide additional security for your tank’s connections, and allow you to effectively manage overflowing water. Tank Overflows also allow you to increase your water tank’s storage, enabling you more ability to plan for volume.
Using the bend to direct water away from your overflow
Simply use PVC solvent glue to glue the bend directly to your overflow in the direction required. Depending on whether your overflow has a male (spigot) or female (socket) fitting, you may require an adaptor. Then glue in pipework onto the fitting as required.
Using the bend as a high level overflow
Note that we also have a range of overflows with flanges which are better suited to be used as an overflow if you prefer to use this style.
When properly installed, your tank overflow should be maintenance-free.
PVC Solvent Glue and primer
If your inlet/overflow issue persists, remove your tank screen and check for floating debris on the water surface. Floating debris such as shavings 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.
