Unfortunetly, for houses that old the sewer design is somehow rather weird. According to the agent and upon site inspection, a few houses share a sewer along the road. Their sewer pipes run to this common sewer located at the back yard of this house that I am interested in. At least the agent is honest to reveal this . All the pipes are underground.
So I guess I would receive all the "gold" from my neigbours...... But seriously, is this the case? Any guru can help? Or apply the golden rule, when in doubt (about fengshui), just pass.
BTW, the house facing is exact South, or S2 (Zhi) facing as in some of the fengshui books.
