How to Choose the Best Rain Barrel Linking Kits

Understanding Your Needs

Before purchasing a linking kit, assess how many rain barrels you plan to connect and the available space. Consider the diameter of your rain barrels, as kits are often designed for specific barrel opening sizes. Ensure the kit includes all necessary components for a watertight seal and secure attachment.

Frequently Asked Questions

What is a rain barrel linking kit?
A rain barrel linking kit is a set of connectors and hoses designed to join two or more rain barrels together. This allows water to flow from one barrel to the next, increasing your total water storage capacity.
Are rain barrel linking kits universal?
No, linking kits are not always universal. They are often designed to fit specific rain barrel diameters or spigot types. Always check the product specifications to ensure compatibility with your existing rain barrels.
How do I install a rain barrel linking kit?
Installation typically involves drilling a hole in the side of each barrel and attaching a connector. A flexible hose is then connected between these ports. Most kits come with detailed instructions, and it's important to ensure a watertight seal.
Can linking kits overflow?
Yes, linking kits facilitate overflow management. When the first barrel fills, the water will flow through the linked system to fill subsequent barrels. This helps manage excess water and prevent spillage around your barrels.
