More Details on Our Top Picks
RTS Home Accents Rain Water Collection Barrel Linking Kit
This kit stands out for its simplicity and straightforward design, making it ideal for homeowners looking to expand their rainwater harvesting system without complicated setups. Unlike the RBL020 kit, which uses brass fittings and is more geared toward irrigation, the RTS kit is geared toward casual users who want quick, reliable connections.

Rain Barrel Hose Connector Kit with Hose, Gaskets, and Hole Saws
This kit makes a strong case for users wanting a versatile, leak-proof connection between two barrels, especially when working with plastic or wooden containers. Compared with the RTS kit, which is more straightforward, this option offers more comprehensive parts including gaskets and hole saws, enabling a more secure seal and broader compatibility. However, the installation process can be challenging for less experienced DIYers, and it’s not recommended for metal drums. Its focus on leak-proofing and compatibility with different barrel types makes it well suited for those wanting a reliable, longer-term setup, though limited to connecting only two barrels at a time.
Pros:- Easy to install with included hole saws
- Provides leak-proof sealing with gaskets
- Compatible with plastic and wooden barrels
Cons:- Not suited for metal drums
- Limited to connecting only two barrels
- Installation may be tricky for beginners

Our verdict“Best suited for those needing a flexible, leak-proof connection between two plastic or wooden rain barrels, accepting some installation complexity.”
RBL020 Rain Barrel Linking Kit with Brass Bulkhead Fittings and Hose
This kit excels for users focused on irrigation, thanks to its brass fittings and 9-inch hose, providing a durable and reliable connection. Compared to the plastic-focused kits, the brass construction offers enhanced longevity and resistance to weathering, making it suitable for more permanent setups. It’s designed specifically for rain barrels with up to 10mm wall thickness, requiring precise hole sizes around 27mm, which can be a challenge during installation. Its focus on irrigation makes it less flexible for potable water use, and the brass fittings are not lead-free, which could be a concern for some users. Overall, this kit is a solid choice for those prioritizing durability and irrigation compatibility, but it’s more specialized.
Pros:- Includes all necessary fittings and hose for easy setup
- Durable brass construction withstands outdoor conditions
- Ideal for irrigation systems with suitable wall thickness
Cons:- Not lead-free compliant

This overflow kit offers a practical solution for managing excess rainwater, making it suitable for those concerned about water pooling around their property. Its lightweight plastic construction and simple design allow for quick DIY installation, similar to the PVC spigot kit but focused on overflow rather than linking. Compared with the hose connector kits designed for linking barrels, this product emphasizes overflow control, helping to avoid flooding or water damage. The limited hose length and compatibility depend on the rain barrel outlet size, which could restrict its use in larger or complex setups. It’s best for homeowners who need a straightforward overflow solution without extensive plumbing.

Not ideal for: Those seeking to link multiple barrels or full water distribution systems
- Material:Plastic
- Color:Black with red accents
- Hose Length:1 meter
- Connector Diameter:2 cm (0.79 in)
- Outside Diameter:25 mm
Our verdict“Ideal for users needing a straightforward overflow solution to protect their property from excess water, but not suitable for linking barrels or complex plumbing.”
PVC Rain Barrel Spigot Kit 3/4″ GHT Garden Diverter Kit with Bulkhead Fitting and Ball Valve (2 Pack)
This kit is tailored for users seeking a comprehensive solution to control water flow from their rain barrels, with included ball valves and bulkhead fittings. Its durable PVC construction and 2-pack design make it suitable for multiple containers, offering more control than basic linking kits like the RTS. Compared to the brass irrigation kit, this option is more suitable for general water distribution and non-irrigation use, with the added benefit of easy installation. However, installation may require access inside the barrel or tank, and the plastic components could degrade over very long periods. It’s ideal for those wanting a reliable, multi-application diverter and valve setup.

The kit’s durability and weatherproof construction make it a reliable choice for outdoor use, especially for those seeking a low-cost, easy-to-assemble solution. However, it doesn’t support larger or metal barrels, and its length may restrict larger setups. Best suited for homeowners with plastic rain barrels looking for a quick, reliable connection.

- Fitting Size:3/4″ GHT x 1/2″ NPT
- Hose Diameter:6 mm
- Package Includes:4 brass bulkhead fittings, 2 hoses with connectors
Our verdict“This kit is ideal for homeowners who want a straightforward, durable connection between two rain barrels for garden watering.”
Rain Barrel Hose Connector Kit to Link Rain Water Collection Barrels
This connector kit makes it easy to double your rainwater capacity with minimal fuss, thanks to included tools like a hole saw and premium seals. Compared with the stainless steel options, its plastic components are lighter and simpler to handle, but may not be as durable long-term or suitable for metal barrels. Its straightforward installation process suits DIYers who want to expand water storage without complex fittings. The kit’s main drawback is that it’s not recommended for use with metal drums, and some users may find the plastic fittings less resilient over time.

- Diameter:1 ¼ inch
- Hose Extension:10″ to 32″
- Includes:hose, gaskets, hole saw
Our verdict“This kit offers a fast, secure way to connect two plastic rain barrels, perfect for garden watering expansion.”
2 Pack Rain Barrel Linking Kit with 12-inch 304 Stainless Steel Hose
This set’s stainless steel hoses provide exceptional durability and resistance to corrosion, making it suitable for long-term outdoor use. Compared to plastic options, the stainless steel hoses are less prone to weathering, though their 12-inch length can limit flexibility in larger setups. Designed for connecting multiple barrels or water tanks, it simplifies complex rainwater harvesting systems. The main tradeoff is the shorter hose length, which may require additional fittings or extension for bigger arrays. This kit is well-suited for users prioritizing durability and premium materials but less ideal for large-scale, multi-barrel configurations without additional components. Best for serious rainwater collectors or those seeking a long-lasting, corrosion-proof connection.

Unlike the stainless steel model, it is designed primarily for plastic rain barrels and includes all necessary components for DIY installation, including multiple hole saws. Its versatility makes it attractive for those with irregular barrel placements or needing to connect multiple containers.

Compared with other kits, its simplicity and built-in diverter functionality optimize it for single downspout connections, streamlining rainwater collection on smaller to medium-sized properties. Its durable rubber construction withstands outdoor conditions, but the 1.25-inch diameter limits its use to compatible downspouts and barrels.

Our verdict“This diverter kit is perfect for those seeking an effortless, adjustable way to divert rainwater from downspouts into barrels for garden use.”
Brass Rain Barrel Spigot Linking Connector Hose Kit
This kit stands out for its solid brass construction, offering high durability for outdoor environments. Compared to plastic alternatives like the Rain Barrel Connector Kit with Overflow Diverter, it provides a longer-lasting, corrosion-resistant option, but it is primarily designed for irrigation rather than potable water use. Its heavy-duty fittings are ideal for users seeking a robust, permanent connection, though the installation involves manual drilling and precise fitting. The inclusion of all necessary components makes setup straightforward for those comfortable with DIY projects. However, it’s not lead-free and isn’t suitable for drinking water, which limits its use in potable applications.

This kit excels in providing a complete solution for expanding rainwater storage with minimal fuss. Its included hole saws and gaskets make installation accessible for DIYers compared to more complex kits like the RBLSS5 Stainless Steel Kit, which offers higher durability but requires more specialized tools and skills. The plastic construction keeps it lightweight and easy to handle, but it may not withstand heavy weather conditions as well as metal options. It’s ideal for users who want a straightforward, flexible connection for multiple plastic or wooden barrels, though it may pose challenges in very harsh environments or with larger, heavy-duty barrels.
Pros:- Easy DIY installation with included tools

Rain Barrel Hose Connector Kit, Linking Rainwater Overflow Barrels
This kit offers a simple DIY approach to expanding rainwater collection by linking multiple barrels, emphasizing a leak-proof connection with included gaskets and a compatible hose. Compared to the Brass Rain Barrel Linking Kit, it’s lighter and easier to handle, but it’s limited to plastic and wooden barrels, making it less suitable for metal setups. Its straightforward installation suits users who want to quickly increase storage capacity without complex tools, although it’s less durable under heavy weather or in exposed environments.

RBLSS5 Heavy Duty Stainless Steel Rain Barrel Linking Kit with Corrugated Hose
This stainless steel kit excels in durability and corrosion resistance, making it suitable for long-term outdoor use and multi-purpose setups. Its kink-free, expandable hose offers flexibility that surpasses plastic or rubber hoses, and the stainless steel fittings provide a premium, rust-proof connection compared to brass or plastic options like the 2PCS Rain Barrel Hose Connector. The need for a 1-1/16 inch hole for installation is a small tradeoff for its longevity, but the absence of mounting hardware means users must secure it separately. It’s best for users with larger, spaced-apart barrels seeking a robust, rust-free solution.
Pros:- Stainless steel construction resists rust and corrosion

2PCS Rain Barrel Hose Connector, Rain Barrel Overflow Linking Kit
This kit offers a straightforward way to connect two rain barrels using brass fittings and hoses, emphasizing ease of installation through simple drilling. Compared to more advanced kits like the RBLSS5 Stainless Steel Kit, it’s less durable and suited for short-term or less exposed outdoor environments. Its brass fittings are durable but not lead-free, which might be a concern for some users.

How We Picked
These products were evaluated based on build quality, compatibility, ease of installation, versatility, and overall value. I prioritized kits with durable fittings capable of handling outdoor conditions and those designed for common rain barrel setups. Ease of use was a key factor, especially for DIY enthusiasts, so kits with clear instructions or included tools ranked higher. I also considered how well each kit manages overflow and prevents leaks, along with their adaptability to different barrel sizes and configurations. The final order reflects a balance of quality, versatility, and affordability, aiming to help various types of users—from beginners to experienced gardeners—find a suitable solution.Factors to Consider When Choosing Rain Barrel Linking Kit
Choosing the right rain barrel linking kit involves understanding several key factors that affect long-term performance and ease of use. While some kits are simple, others include advanced features like overflow management or versatile fittings. Considering these factors will help you avoid common pitfalls like leaks, incompatibility, or complicated installation. The right kit should match your setup, budget, and DIY skill level, making your rainwater harvesting more efficient and reliable.Compatibility with Barrel Sizes and Spouts
Not all kits fit every rain barrel. Some are designed specifically for standard 55-gallon drums, while others accommodate larger or irregular shapes. Ensure the fittings are compatible with your barrels’ spouts or overflow outlets, as mismatched sizes can lead to leaks or unstable connections. Checking the product specifications for diameter and connection types helps prevent costly mistakes and ensures a seamless setup.
Material Durability and Weather Resistance
Since rain barrel linking kits are used outdoors, durability is essential. Fittings made from brass or stainless steel generally resist corrosion better than plastic ones, especially over multiple seasons. However, higher durability often comes with a higher price. Consider your climate—if you experience harsh weather, investing in heavy-duty materials can save you money and hassle in the long run.
Ease of Installation and Included Tools
Some kits come with comprehensive instructions, gaskets, or even tools like hole saws, making installation straightforward for DIYers. Others require additional purchases or more complex setups. If you’re new to rainwater harvesting, choosing a kit with clear instructions and simple fittings can greatly reduce frustration and setup time.
Overflow Management and Leak Prevention
Overflow kits or diverters prevent water from spilling over the sides of your barrels, which can cause erosion or water damage. Look for kits that include overflow hoses or diverters suited to your rain collection system. Proper overflow planning helps maintain system integrity and reduces maintenance needs.
Value and Additional Features
While a higher price often indicates better materials or extras, it doesn’t always guarantee better performance for your needs. Consider whether the kit offers the number of connectors, hoses, or fittings necessary for your setup. Additional features like quick-connect fittings or leak-proof seals can add convenience, but prioritize what aligns with your intended use and budget.
Frequently Asked Questions
Can I connect different brands of rain barrels with a linking kit?
In many cases, compatibility depends on the size and type of spouts or fittings on your barrels. Some kits are designed with universal fittings that work across various brands, while others are more specific. Always check the diameter and connection type before purchasing to ensure a secure fit and prevent leaks. Using adapters may help if the fittings aren’t directly compatible, but compatibility isn’t guaranteed across all brands.
Is it better to choose a plastic or metal fitting for outdoor use?
Metal fittings, especially brass or stainless steel, are generally more resistant to corrosion and last longer in outdoor conditions. Plastic fittings are lighter and often less expensive but may degrade over time under UV exposure or harsh weather. For long-term durability, metal fittings tend to be the better choice, especially if you plan to use the system for multiple seasons without maintenance.
Do I need special tools to install a rain barrel linking kit?
Many kits are designed for straightforward installation and include necessary tools like gaskets or fittings. However, some may require a hole saw or drill to create connections, especially with diverters or overflow hoses. If you lack tools or experience, opting for a kit that includes everything or requires minimal modification can simplify the process and reduce setup time.
How do I prevent leaks in my rain barrel connection system?
Ensuring tight, well-seated fittings and using high-quality gaskets significantly reduce leaks. Applying a small amount of waterproof sealant around threaded connections can also help. Regularly inspecting connections and replacing worn gaskets or fittings prolongs system integrity. Choosing kits with durable materials and clear instructions also minimizes installation errors that can lead to leaks.
Can overflow kits handle heavy rainfall without spilling?
Overflow kits designed with larger hoses and diverters are better equipped to manage heavy rainfall, directing excess water safely away from your property. It’s important to select a kit with a sufficient hose diameter and proper attachment points to handle your area’s rainfall intensity. Proper placement and regular maintenance ensure your overflow system functions correctly when needed.
Conclusion
For most users, the RTS Home Accents Rain Water Collection Barrel Linking Kit offers an excellent balance of durability, ease of installation, and versatility, making it the best overall choice. Budget-conscious gardeners will find the Rain Barrel Hose Connector Kit with Hose, Gaskets, and Hole Saws provides solid functionality at a lower cost. For those seeking premium durability, the RBL020 Rain Barrel Linking Kit with Brass Bulkhead Fittings and Hose is ideal. Beginners or DIY newcomers should prioritize kits with included tools and straightforward instructions, like some of the simpler plastic options. Finally, if overflow management is a priority, select kits with diverters and larger hoses to prevent spills during heavy rains.
