After permits were filed, we discovered that the proposed location of our equipment would likely cause the roots of 2 18" trees to be cut through, so paid $2100 to move the equipment to the back, corner of the yard. We were told this was possible, but the plumbing contractor says it has to be 5' from any fence. The main contractor says it'll be fine next to the fence. Does anyone know how to find the answer somewhere. I live in Austin, TX.
