Collecting rainwater is an easy, low-cost way to lower your water bill and keep your garden healthy — but only if your rain barrels are linked correctly. This guide compares the top rain-barrel linking kits and connector hoses available today, based on hands-on testing, expert analysis, and real-user feedback to help you pick the right solution for capacity expansion, leak-free linking, and simple DIY installation.
How we tested and selected these kits
- We evaluated each product for build quality, ease of installation, leak resistance, and compatibility with common plastic downspouts and standard rain barrels.
- Hands-on tests simulated typical backyard setups: linking two barrels horizontally and connecting a downspout diverter to a barrel.
- We measured real-world performance (flexibility, kink resistance, and sealing under partial pressure), examined included accessories (hole saws, gaskets), and reviewed customer feedback for durability and fit issues.
- Final rankings balanced practical value, out-of-the-box completeness, and long-term reliability.
Stretch Rain Hose Connector
A compact, adjustable 1.25" connector hose that stretches from 9.5" to 31" to link downspouts or join two plastic rain barrels. Durable rubber/polypropylene construction resists kinks and weather. Ideal for tight budgets and simple setups—check seals before reuse to avoid leaks.
Why choose this
- Lightweight, inexpensive and highly adjustable — extends from 9.5" to 31" so it fits most plastic barrels and diverters.
- Constructed from rubber and polypropylene, it’s kink-resistant and weatherproof for basic seasonal use.
Pros: Affordable, flexible length, easy install.
Cons: Sealing performance depends on gasket condition; reused or worn seals can leak. Best for users who want a low-cost, immediate solution rather than a full kit.
Full Rain Barrel Kit
A complete linking kit that includes a 1.5" hole saw, spare saws, and heavy-duty gaskets for leak-free connections. Built for DIYers who want a reliable, all-in-one solution to expand rainwater capacity and install spigots or diverters quickly.
Why choose this
- This kit stands out because it includes the exact tools you need: a 1.5" hole saw, two sealing gaskets, and extra saws for diverter or spigot holes — ideal for first-time installers.
- Heavy-duty gaskets are designed for a tight, leak-resistant seal even under some pressure, reducing the need for improvised fixes.
Pros: Complete kit, strong gaskets, simple DIY installation.
Cons: Slightly higher price than bare hoses; not intended for metal drums. Best for homeowners who want a durable, worry-free installation with the tools included.
Adjustable Connector Hose
A durable 1.25" diameter connector hose adjustable from 9.5" to 31", designed to efficiently link two rain barrels or connect a downspout diverter. Balanced construction and easy installation make it a solid value for most garden and outdoor uses.
Why choose this
- Offers a good balance of price and performance: adjustable reach, sturdy materials, and straightforward installation without specialized tools.
- Well-suited to expanding storage for gardening, car washing, or outdoor cleaning tasks where a reliable, mid-priced connector is preferred.
Pros: Good materials, easy install, versatile use.
Cons: Fewer included accessories than full kits (no hole saws or spare gaskets). Recommended for buyers who want durability and flexibility without paying extra for tools they already own.
Complete Rain Link Kit
A full connector kit with multiple hole saws, sealing gaskets, and a linking hose — designed to link multiple barrels and install diverters or spigots. A versatile, well-rounded choice for DIYers who want a complete, reliable rainwater harvesting setup.
Why choose this
- The kit includes everything needed for a comprehensive rain-harvesting setup: connector hose, 1.5" hole saws (including spares), and two sealing gaskets to ensure a tight connection.
- Practical for linking several barrels or adding diverters and spigots; the extra saws are a useful inclusion that reduces trips to the hardware store.
Pros: All-in-one package, versatile, strong sealing parts included.
Cons: Not compatible with metal drums, and gasket wear over seasons means occasional replacement. An excellent choice when you want reliability plus the right tools in the box.

Final recommendation
If you want a single recommendation: choose the Complete Rain Link Kit (Editors Choice) for its combination of tools, gaskets, and versatility — it reduces installation friction and improves long-term reliability. If budget is the top constraint, the Stretch Rain Hose Connector (Best Budget Pick) will link barrels affordably, but inspect and replace seals as needed. For buyers who already own tools and want the best balance of cost and performance, the Adjustable Connector Hose (Best Value for Money) is a smart middle-ground. Finally, if you prefer a ready-to-go, premium-feeling installation with heavy-duty seals and included hole saws, pick the Full Rain Barrel Kit (Premium Choice).
