You can connect two or more water butts together using a water butt linking kit.
When one fills up with water, it will transfer to the next water butt in the row. It’s an economical way of storing more water without purchasing a large rainwater tank.
Just connect either end of the linking kit to each water butt and some of our water butts have templates in the sides to make drilling a hole easy.
The kit can be positioned at the top or bottom and if you do so at the bottom, the butts will fill at the same time. If you position the kit at the top, the next butt will fill once the previous water butt has filled.
