Janet, this may sound long but it's not hard, except the drilling maybe.
The barrels are connected at the bottom with 3/4" PVC pipe.
Each joint, on the outside is a 3/4" male threaded to slip connectors.
The male thread goes through a 1" hole, drilled through the barrel and screws into a female 3/4" thread to slip connector.
Now I needed some type of gasket to make the connections water tight, the hardware store had fiber washers with 1" hole for $1.25 each, but I remembered I had a large piece of rubber from a roof repair job so I cut the gaskets from that.
I cut 3" squares of rubber, clamped them between two pieces of wood and drilled through the lot.
The gaskets are on the inside and work great. The drill bit was the most costly item. (not counting the beer)
Each barrel is connected at the bottom so they all fill equally as it rains. But I do need a larger overflow, maybe 3" dia.
Well a picture is worth 1000 words so I clicked one, Another hard part about this job is holding the fitting on the inside of the barrel.
