Well sealing with a knife perforator on 6″ well casing 317′ deep in Wayzata, MN. The perforator required 6677lbs of pull on 25 year old well casing. Bob L. says, “pull with a light hand and use a drillers knot on the sandline to keep it clean and prevent the perforator from getting stuck.” Protect your groundwater!
