It should be high enough up on the barrel to fit a bucket or water jug underneath. Make a 3/4-inch hole to properly fit the spigot you bought. This is the standard size for a spigot; if you're using a different sized-spigot, make sure you drill the right sized hole so that it fits into the side of the barrel. Put caulk on both the inside and the outside of the barrel. Put the spigot and the coupling together. Use Teflon tape to wrap the threaded ends to create a tight seal and prevent leakage. Put a washer on the threaded end of the coupling and insert it through the hole in the barrel from the outside. Slip another washer over the pipe from the inside. Attach the bushing to hold the spigot in place. Follow the directions for attaching the type of spigot you have. You may need to attach it differently than specified here. Drill a second hole a few inches from the top of the barrel. It should be 3⁄4 inch (1.9 cm), or the same size as the first hole you drilled.  Squeeze a circle of caulk around the hole, both inside and outside the barrel. Slip a washer on the hose adapter and put it through the hole from the outside. Put another washer on the inside threads, attach some Teflon tape, and attach a nut to tighten the assembly. You can attach a garden hose directly to the valve.  If you have a second barrel to use as an overflow barrel, you'll need to drill a third hold in the first barrel. Drill it at the same level as the spigot several inches to the side. Then drill a 3⁄4 inch (1.9 cm)-hole in the second barrel at the same level as the hole you just drilled in the first one. Attach hose adapters to the holes in both barrels as described above. If you're using a third overflow barrel, the second barrel will need a second hole so you can connect it to the third barrel. Make a second valve on the opposite side of the barrel at the same level. Make a valve in the third barrel as well.
