- Effectively manage overflowing water and make it easy to connect standard plumbing fittings to your tank with our tank overflows. Tank Overflows provide additional security for your tank’s connections, and also allow you to increase your water tank’s storage, enabling you more ability to plan for volume.
All our overflows can be paired with mosquito proof screens or flap valves, and some can be used to increase your tank’s rainwater storage capacity.
Made from UV-stablised UPVC for longevity and AS4020 compliant, our tank overflows are available in a wide range of sizes and fittings to suit your tanks and stormwater pipes.

What if it is leaking after many years installed? How do you suggest re-sealing?
Hey James, we would suggest replacing the gasket or using silicon
Most overflow pipes leak at the top fitting because pvc pipes expand and contract, poly tanks flex with varying water levels and seasonal variations cause the ground to expand and contract. The overflow pipe should be safeguarded by ideally fitting a swivel expansion joint.
The high level overflows are also a real trap for the unwary. The overflow capacity requirement should always be hydraulically calculated and raising the overflow height lessens the outlet's overflow capacity. Also, high level overflows should never be fitted to a flat roofed tank.
Birds and insects maybe mesh the overflow
