Feng Shui Leaks

Dear Sir
I'm a strong wood person, NE is my Excellent sector, SW is my prosperity sector, South is my Disaster sector. I've attached a picture & floor plan of my 2 storeyhouse, it hasa small garden & the roof is Flat. Lighting in all the roomsis good during the day. But according to my sister's friend, my house's fengshui is bad, wealth is being flushed away due to the following reasons:
(1) There is a drainin my front porch, it comes from outside extending into my front porch and goes out from the side of my main gate ??please refer to photos & floor plan attached for your reference; drain is in yellow)??When it rains, water (wealth) will flow infrom outside & flow out from the side of my main gate.
(2)There is a watertapin my front porch just outside my living room, used for drawing piped undergound water to water plants & to wash clothes.
(3) The toilet is located next to mymain gate (main gatefacing West which is my longevity) , affecting my health.
(4) There is a gentle slope just outside my main gate, according to my sister's friend it signifies deterioration, no advancement..
(5) My living room's main door is directly facing my living room's back door (pls refer to floor plan attached for your reference), I can't remember what her friend said about it.
The way she said it seems like the end... I hope to have your expert views, advise. Are there any remediesthatI couldimplement for the above leaks?
Deeply appreciate
Best wishes
