After arriving to the property to discuss the drainfield with the homeowner I began by locating a manifold at the top of the hill with 1 2 inch gate valve followed by a series of four ball valves in meter box that vary in size, after beginning to probe out the drainfield the homeowner politely informed me did they currently are not interested in any preventative measures that will exceed 1 or $2000 and then if any proposed work would exceed that that he does not want to waste either of our time and would wish not to proceed
