Linking & Overflow Kits

A linking kit joins two water butts with a short hose near their bases, so when the first fills, the second fills too. It’s an easy way to double your storage without buying one huge tank.

You’ll also find overflow kits here, for butts filled straight from a gutter with no diverter. Most kits need a hole drilled in each butt, so check the hole size on the listing. Our linking guide explains the different set-ups.
