How to Connect Multiple Rain Barrels

Rain Barrel Connector from Garden WatersaverWant to collect loads and loads of rainwater? Then create a roof-to-barrel rainwater harvesting system that ties together multiple rain barrels! Fed by just one Garden Watersaver Downspout Diverter, multiple rainwater barrels can be attached together to create a larger storage system. (The more downspout diverters and rain barrels attached to your house, the more rainwater that will be caught from your entire roof area and gutters every time it rains!)

Rainwater Contain OptionsLinking together different types of rainwater barrels and containers can be done in various ways, for multiple uses. These connections are made using our Garden Watersaver Rain Barrel Connector Kits.

Connecting a closed-top barrel to an open-top barrel is one option that can be used, as shown in the picture above. This dual-top setup increases the water volume saved while only requiring one barrel spigot. The water level fills and empties from both barrels at the same time, providing extra water pressure, too.

Connecting at the bottom of the barrel is a bit tricky for the closed barrel portion and requires special instructions. We recommend using our Barrel Connector Kits at the top of each barrel where the pressure is minimal; if a leak occurs at the bottom, you will lose your entire water supply.

Also note in the example above, the hose connection on the right side of the trash can can be used to move excess water to another area in the yard with a simple tilt of the can.


Create additional rainwater storage by linking together multiple rain barrels! Here’s how it’s done:


Drill a Hole in a Rain Barrel

Drill a 1″ hole in each
rain barrel to be connected.


Heat the Hole in the Rain Barrel

Heat the hole area slightly to
soften the plastic of the barrel.


Add the Plug to the Rain Barrel

Insert hose coupling into each barrel;
the coupling is harder than a barrel,
so tighten firmly (pliers use OK)


Connected Rain Barrels Ready to Use!

Attach the hose between the
two barrel’s couplings. Done!
(Any type of barrel can be linked!)
