Step 1: Parts and Tools
Step 2: Cut a hole for the downspout
Measure and cut a 7 3/4" hole in the top of the barrel. A jigsaw or a spiral-cut saw (Rotozip) work best for cutting this hole.
Note: The 7-3/4" hole is for the 9" basket. Baskets of all shapes and sizes can be found wherever pond supplies are sold. Adjust your hole accordingly.
Step 3: Cutting the overflow hole
A 2-3/8 circle will be used for your overflow hole. Determine what side of the barrel you want your overflow hole to be on. Measure down from the top of the barrel approximately 4 inches. The bottom of the 2-3/8 circle should be slightly below this mark.
Again, using an appropriate saw, cut out the circle you just traced.
Note: The 2-3/8" hole is appropriate for the 2" PVC male adapter. It will be too big if you use 1-1/2" fittings.
