In geomantic omen, water is regarded as wealth. For example, if the house leaks, it will leak, and if you pour water into the house, you will make money. But if the toilet turns inward, it's sewage, not money, but the so-called "Erhei" Huang Wu, who is a sick star, and should pay attention to the health of his family. Keeping your home clean and tidy is the first element of good feng shui.
I hope it helps you.
