due to contractors lousy workmanship the rain water is flowing toward my house. Contractor blame the sinkage of the ground that caused the problem. I planned to install 130mm width drain along and across the floor of the car porch but read about the bad fengshui to have drain in front of the main entrance. The drain will be connected to the existing big drain which is much dipper than the new drain. Have any advise on this?
