Step 4: Attach Garden Hose Valve

Drill a 1" hole near the bottom of the barrel. The adapter and washer go on the inside of the barrel. The valve goes on the outside. The toughest part of this is that it requires someone with a really long arm to hold the adapter while someone else screws on the hose valve.

Where did you get the parts for the hose connectors? I checked Home Depot and Lowes and couldn't find anything like these...

Home Depot and Lowes _should_ have those parts. However, i found them at a local farm supply store, Rural King. With hindsight, I'd use larger-diameter hoses for the project. Garden hose is just too small to allow a significant amount of water to flow at "rain-barrel pressure".

Or you flip the rain barrel over and have someone stand inside it and hold the 2 parts.
