After all the money I have paid for digging up the backyard and installation, you would think that he would have a little more professional concern. My constant question had been when he was digging it all up and laying down new pipes: Is that pipe going to be wide enough for all of the water coming down in the new gutters? I had had a new roof put on and garge built in. the first rains after that had flooded out the garge as the roof people had put it on the gutters wrongly. three tries latter, it is strill not right.

Anyway, the plumber assured me, yes.
That was the widest pipe you could get and it would do the job. Can you please. please recommend someone to me WHO KNOWS ABLOUT THE RATIO OF WATER FLOWING DOWNWARDS, SIDEWAYS, ETC, WHEN THERE IS MAXIMUM DOWNPOUR FROM A STORM IN BRISBANE. I am in desperate need of good advise from someone who can work things out. I have abridged the story of my woes soemwhat here and have had so many things go wrong with the plumbing that I just don't know where to turn.

Wow, another non returning contractor hits the dust trail. Now you can fully understand why I strongly feel the average home owner is far better off going to a home center buying the materials and doing the work themselves.

Storm drainage is not like a lot of USA handymen think with a hit and miss approach.

Storm drainage is much more complicated then regular house / office building plumbing drainage systems.
