Re: Sludge in rain water tank 47Nov 07, 2015 10:15 pm einadia It's hard to know which would be worse - (hopefully only occasional) blockages because of too short a distance between the downpipe and the leaf diverter, or (possibly frequent) water loss and splashing where it might be a nuisance because of too big a distance. What's your opinion? It really depends on your own situation. If you were reliant on harvested rainwater for potable use, you would be concerned about any yield loss and would almost certainly opt to have the pipe's outlet closer to the mesh as most do and monitor the diverter for large objects causing blockages. If yield loss was not a concern, then nuisance value and the visual effect may be. The way the current crop of leaf diverters are designed, the onus is on the owner (or installer) as to how close to the mesh the downpipe is fitted. I have seen many leaf diverters with blockages between the mesh and the bottom of the downpipe and many leaf diverters are installed in situations where climbing a ladder to clean them presents a considerable safety hazzard. einadia "During lighter rainfall, a lot of water travels down the downpipe's inner wall that is furthest away from the house and the reason for this is because the section of downpipe that is sloped towards the house wall transfers water by surface adhesion to the downpipe's outside wall." By "outside wall", do you mean the outer surface of the pipe, or the inside surface of the longer bit of pipe further from the house? The pipe's inside wall that is furthest from the house. In my previous post, perhaps I should have written "During lighter rainfall, a lot of water travels down the downpipe's inner wall that is furthest away from the house and the reason for this is because the section of downpipe under the eave that is sloped towards the house wall transfers water by surface adhesion to the vertical section of the downpipe's outside wall." If you look at the photo in the previous post, you will understand what I mean. einadia "Make sure that the reservoir completely drains and does not retain water and debris." Which reservoir? The leaf diverter's reservoir under the mesh. Believe it or not, not all leaf diverters completely drain! This is why you sometimes see weeds growing inside leaf diverters. 3in1 Supadiverta.

Re: Sludge in rain water tank 48May 14, 2016 5:55 pm [quote="SaveH2O"] It is also easy to install a cheap and simple DIY sediment trap into the wet system's pipe work. The trap is installed 4-5 metres past an elbow or tee as it must be in a non turbulent section of pipe to capture settled bed load. As you can see in the diagram below, when the very slow travelling bed load reaches the opening in the 45 degree junction, it simply drops down and is later flushed through a reduced sized pipe at high velocity. Hi SaveH2O, thius is interesting, but I'm not quite sure what you mean by the "flushed through a reduced sized pipe at high velocity" bit... 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 link below is a one year summary of a 4 tank system in QLD that has the sediment traps (2 x 100mm DWV pipes). The rain harvesting system is probably the best in the district. viewtopic.php?p=1146540#p1146540 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: Sludge in rain water tank 50May 16, 2016 10:50 am I've set up one of these sludge pipe systems here, but haven't reduced the size of the end of it, so just straight out of my 100mm pipes. I'm amazed at the amount crap that sits down the bottom of these pipes, and so glad that I put them in. 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.
