Good news, Have put in 7 wells so far. Please purchase waterhole by Bob Mellin. Inexpensive helpful Lil book. I can't say enough about My $300.00 Borzit boring system. Never used it for a well,Myself But will this summer. I recently doug 2 pits and drilled 30 ft. under a concrete slab. Replaced a rotted cast iron 2" drain line with PVC. Also the owner Jim sent Me a replacement part I broke at no charge. www.borzit.com Get the optional 5" Auger. Have fun. Boston!, P.S. Don't listen to the Nay sayers ! I use My timber wolf offset drill motor to power it.
