Here is the problem. Sewer line (cast iron) needs to be replaced in house 52 years old. Unfortunatley—a maple tree was planted directly over the line by previous owners about 40 years ago and some of those roots have entered pipe (confimerd by video). Is there anyway to resolve this problem without damage to or removing tree??
Regarding the route of the line–I assumed that the route must be straight line from point A (house) to point B (city connection). Wouldn’t the change in this instance, to avoid tree, result in right angles and thereby diminish the efficiency and flow of the line?
Can Trenchless technology be used where roots have already penetrated line? Does anyone know of a trenchless contractor in the Washington, DC area, and is trenchless technolgy any less expensive than the alternative?
