In order to get the water you've collected out of the barrel, you'll need to attach a spigot. Ask your local hardware store for a drill bit that will match the diameter of the spigot you've chosen. Cut a hole near the bottom of the barrel for the spigot and knob. Attach the spigot and the included gaskets to the barrel. Be sure to use caulk behind them so you won't have leaks around the new hole.

Good winter care will ensure that your rain barrel is ready for use the following year.

When temperatures start to approach freezing, disconnect your rain barrel from the downspout.

Turn the barrel upside down – if it is left upright, the barrel will fill with water, freeze and crack.
