Overflows

Tank overflow kits are designed to safely direct excess water away when your tank reaches capacity. They help prevent overflow damage and protect the surrounding area.

When a tank fills during heavy rain, overflow systems ensure water is discharged correctly instead of pooling around the base. This reduces pressure on the tank and prevents erosion or flooding.

Overflow kits are commonly used alongside tank inlet strainers and first flush diverters as part of a complete water management setup.

They are suitable for use with water tanks and can be added in tank & pump package deals.
