On the front of the barrel, I stuck a thin white pipe (called an overflow pipe), which led underground to the downspout. Using some tools, we were able to break it and stick the overflow pipe inside. This way, any excess water that the rain barrel doesn’t have space to store, will just resume its way down the downspout.
We can turn the sprinkler on by turning the spigot at the bottom of the barrel and plugging the pump in. The entire rain barrel is estimated to take around 20-30 minutes to completely empty after being turned on.
