Well I was all set on putting my pole in the ground after the "Well Drilling" mcompany brought out the pole for me. I thought it was a 3 1/2" x 20' pole! Turns out it's a 4 1/2" x 20' foot pole. Dug a hole 8' deep too! Guess I should have checked the size of the pole before drilling holes in it for the rebarb. may be a costly mistake, I hope that the Well copmpany ill take back the pole. If not, do they make a mount for a 4 1/2' pole/pipe?? Take one step forward and three back I'm afraid.
