Does the septic tank built under the stairs have an impact on Feng Shui?

No way! Septic tanks are usually built on one side of the house! Even the buildings in the community are the same! Never face the gate! Otherwise, fate has melted, and disaster is imminent! Why do we have to do that？ Because first, I know some geomantic omen, and second, I have produced septic tanks! There are so many installation sites, I haven't seen them built like you said!
