Re: Sludge in rain water tank 49May 14, 2016 8:30 pm Firstly, you can only reduce the pipe size if you have leaf diverters fitted to the downpipes. This is to safeguard against a dead bird etc being washed into the wet system and then trapped by the smaller pipe. The pipe immediately after the junction is reduced in size to minimise water loss and to reduce costs. Because the pipe is reduced in size, it flows with a higher velocity when drained than would a larger pipe.

The required first flush system that the council requires, to me is a waste of time, and I could really do without them. Other than the last 500mm of my downpipes are under the ground, and most of that is mostly shaded anyhow. Owner Building at Jimboomba Woods in Logan City Qld.
