Rain Harvesting Tank Overflow Extra High Flanged
Installing a Rain Harvesting Tank Overflow Extra High Flanged is a super simple way to boost your rainwater tank’s capacity so you can store more water.

Boost your tank’s capacity
With their curved 90 degree bends, our high level tank overflow outlets raise the level at which your tank water begins to overflow. Every extra millimetre of water over a square metre gives you another litre of water in your tank. By adding up to 120mm to your tank’s capacity, this significantly boosts the volume of water you can store.
Store and use more water
By adding volume to your pre-existing tank you can store and use more water. The added capacity wastes less water during high rain periods and gives you more water to use around your property.
- If you do not have an existing tank overflow hole in your tank, use your tank overflow as a template to mark the size of the hole you need to cut in the side of your tank, then cut using a holesaw. You should position the hole so that when your overflow is installed, the highest water level will sit below the level of the bottom of the tank inlet and/or tank inlet screen.
- Slide your tank overflow into the tank overflow hole so that the bend faces up inside the tank.
- If you have an existing tank overflow hole and doing this means the open end of the bend will sit above the level of the tank inlet and/or tank inlet screen, orient the bend diagonally or trim the top of the overflow.
- Apply silicone to the flange on your tank overflow, push it against the tank, then screw in place through the provided screw hole guides.
