Downpipe compliance question- rainwater tank 6Sep 01, 2017 9:17 pm SaveH2O The only rainhead leaf diverter that I recommend is the ICON Leaf and Debris Controller Also as I don't have the computer skills to put both your quotes in the same reply - Is it possible at some time in the future for me to have a rainhead leaf diverter like the one you suggested above retrofitted ............... with the gutters and 90mm down pipes I have that currently have no rainhead ?. If yes, please do PM details once you introduce it for sale.... any recommendations on plumber to install in Melbourne also welcome. Re: Downpipe compliance question- rainwater tank 7Sep 03, 2017 11:01 pm You can buy the ICON diverter in Bunnings for $38 but I intend to also supply them separate to the kit I mentioned and post free at the same price in the Melbourne metro area. I will PM you soon. A big mistake that people make is to fit leaf diverters unnecessarily high. All leaf diverters need maintenance and safe access is important. Because the ICON diverter's outer filter now has a steep sloped non wire mesh straight surface that doesn't trap debris, it is low maintenance but there is an inner mosquito proof wire mesh filter that does require occasional close up inspection. Fortunately, the outer filter lifts up on two pivots and inspection is very easy. I know a good plumber who has a passion for rainwater harvesting but he is in the outer SE suburbs. I can't recommend a lot of plumbers I come in contact with. The photos below show what happens when a leaf diverter retains water or doesn't flush debris. Sorry about the poor quality of the first photo. I also don't recommend the 'bucket' type of leaf trap (they have an inner mesh filter), the bottom photos might give you a laugh.

I'm in south east, so might be in plumber's range. Would be great to get advice on what is possible at this stage. Yikes re: types of sloppy work you see.

Re: Downpipe compliance question- rainwater tank 12Nov 07, 2018 11:48 pm Well in an article (2016) the NCC mentioned that to achieve a 6 star standard rating there must be provided a minimum 2000litre rainwater tank (+other specs). How do you cite that in a drawing? The article https://www.nationalpolyindustries.com. ... australia/ This link for Victorian 6 star achievements notes! https://www.google.com.au/url?sa=t&sour ... 1593928881 I get this requirements where are they specified: "Buildings will need to be designed to ensure that roof water from a minimum of 50 square metres of roof catchment area is: collected by a drainage system (gutters and downpipes); and stored in a minimum 1000 litre rainwater tank; [I need the standard cited, what regulation?; is it relevant to BCA standard?] and is plumbed to at least a toilet or water heater or all laundry cold water outlets." Sustainable Design Requirements For New Houses, House Extensions & Transportable Buildings Development Guide No. 19 Any help welcomed! Cheers Re: Downpipe compliance question- rainwater tank 13Nov 08, 2018 7:04 am The requirement and regulations for rainwater tanks varies between states and even regions within States. Your situation depends on where you live and sometimes your council wikll have over-rides. There is not a one all-encompassing rule and not all States require water tanks on new homes. The 2,000 L tank servicing a minimum 50 sq m roof catchment area is a Victorian 6 star requirement (are you in Victoria?) but a tank is not required if you specify a gas boosted solar HWS or when the property is connected to recycled water...water that you are charged for. "Roof catchment" is deemed to be the roof area as looked at as a flat plan area but factored for the slope by using a multiplier found in AS/NZS 3500.3 which allows for wind driven rain. For example, the common 22.5 degree roof slope is factored as 1.21 which would give a plan area of 40 sq m draining to one downpipe a factored or roof catchment area of 48.4 sq m. In this situation, two downpipes would be required. Note that a standard Victorian slotted 115mm quad gutter would not be compliant to drain a 48.4 sq m roof catchment area in any case. NSW is bound to BASIX. South Australia has a tiny 1,000 L mininum tank capacity requirement and they don't allow the use of manual switching devices! This variation is found in the NCC. The tank size is also dictated by local council rules which may include a detention requirement. In these cases, the tanks can be very large. Different State variations are found in the NCC but local councils can override national regulations and these mandates do not appear in the NCC. Your builder should know the local council overrides if any. The BCC minimum roof area harvested mandate I mentioned earlier is one example. 3in1 Supadiverta.
