Feng shui installation of rural family water tower

I've been thinking about this problem. It is popular to install water towers on the roof now. It's convenient, but I don't think so!

Because, in Feng Shui, water shower is a very bad problem. If you really want to press, press in the direction of favorable water, not in the middle. If the conditions are right, I think it is best not to put it on the roof!

My house is also on the roof, and I always feel inappropriate!
