FENG SHUI AND CLOGGED DRAINS

Some Feng Shui masters say that clogged drains deplete finances, health, aspirations, travel, clog sinuses, wreak havoc in general.  Then there are other Feng Shui masters who pooh pooh such beliefs. 
Anyway, my mum believes that the damaged drain in her house needs to be repaired as it has caused rubbish to be clogged there and also the flow of water from the house to the main drain outside the house is very slow.  So in a way, clearing the broken drain and making sure that it is not clogged would be a good thing regardless of whether finances would be depleted or health would be affected.
