The concrete pad on which sat my 750 gal. water tank had a crack in it and after Hurricane Michael the tank started listing to one side. My well guy said it was nothing to worry about and that it would not fall. It did put pressure on one of the 3" water lines and an elbow fitting two feet in the ground started to leak really bad. I was afraid of digging that line up and repairing it myself as it was on the side of the tank that was leaning. The well man decided it best for us to pour a new concrete pad and move the water tank and then repair the line. Here is a picture of the new pad.
