Some users wish to connect multiple rain barrels together to optimize water storage from a single downspout. This can be done by replacing the assembled "L" connection of the 2nd overflow barrel with a "T" connector available from Spruce Creek Co. This fitting allows you to connect any number of barrel in series through the overflow located on the back of each barrel. The exit overflow of the last barrel will remain available to disperse any excess rain water once all the barrels are full. The "T" connector and linking instructions are both available below.

Although connecting barrels is a useful tool, we do suggest that rain barrel users should consider utilizing multiple downspouts on their home to maximize the catchment volume their roof can provide.

linking barrels with "overflow T connector"

Two or more barrels can be connected together by replacing the overflow fitting on Barrel 2 with a special T Connector.
1. Locate 1st barrel in position desired under downspout.
2. Position 2nd barrel next to it, preferably less than 1 foot away.
3. Remove the overflow hose and fitting from barrel 2. (unscrew)
4. Thread the new T connector into the second barrel (and turn until the two open ends are horizontally parallel to ground).
5. Now attach overflow hose from Barrel 1 to closest side of the T connector on Barrel 2. Cut hose as necessary to prevent unnecessary slack between barrels.
6. Take the original overflow hose removed from barrel 2, and connect to the other side of the T connector. Please note that there is a small screen that is located between the original ‘L’ fitting and the overflow hose that was on barrel 2. Remove this screen and insert between hose and T connector (exit side) to prevent insect and animal entry into the barrel from the overflow.
7. Turn the T connector on barrel 2 so that it is slightly higher on the exit side than it is on the entry side. By doing this, water will flow into the 2nd barrel (until full) rather than flowing straight through the connection.
