I was able to get rain barrels at my local plumbing store for the low price of $13 a piece so I got two. Now they do not have cutoff valves so in this video I show you how I was able to put them in.
1″ ballvalve threaded.
1″ male adapter (threaded on one side and not the other.)
1-1/4″ hole bit with 1/4″ bit in the middle
