If the corner downpipe drains to a stormwater system or a pit, then how is the water diverted uphill through the wye junction to the top of the tank? There is the possibility that the downpipe connects to another downpipe, forming a loop or 'charged' wet system. This is done when additional downpipes are diverted to meet a requirement to harvest a minimum roof area, do you have a minimum roof harvest area requirement? You can quickly check the flow paths by seeing whether the tank's overflow pipe and the corner downpipe connect to a common sub surface pipe. A wet system retains water in the pipes to the level of water at the top of the vertical riser. If this is the case, then there are also the concerns about obvious mosquito access to the standing water at 3 entry points (no leaf diverters or a flap valve are fitted) as well as the wet system eventually either stagnating or blocking (or both) due to the build up of crud and organic matter and no visible means of flushing the system. Note that your area may not require these fittings but meeting compliance does not guarantee good design. The only first flush diverter that I can see is useless. Yours uses a 90mm uPVC stormwater pipe, these are measured as an outside diameter, the internal diameter is 86.2mm, giving a volume of 5.8 litres per meter and the collection pipe would be little more that 1 metre long. If the downpipe does drain to a point of discharge, then no water will flow to the first flush diverter (and the tank) anyway. If the corner downpipe does connect to another downpipe as a closed loop wet system, then the other (third) downpipe's first flush will still be in that downpipe when the small first flush diverter is full. The first flush diverter will mostly fill with the settled water retained in the vertical riser since the last rain event as very little of the crud being drained down the corner downpipe will find its way up the wye junction. The minimum flushing velocity required for a horizontal 90mm pipe is 0.7 metres per second. This equates to 5.8 x 0.7 x 60 = 243 litres per minute but the wet system pipe is vertical, not horizontal. If there are 3 downpipes diverted to the tanks, then the total roof area drained to the tanks needs to be known so that the flow rate during a 1:20 ARI can be calculated and compared with the 90mm overflow pipe's maximum drainage capacity. Most plumbers don't know the overflow capacities of water tank overflow outlets. Asking the question is a good test that nearly all plumbers will fail because they are not trained in rainwater harvesting. There is a submersible pump fitted, make sure that it hasn’t been plonked directly on the first tank’s floor (as many are) unless the pump has its own stand to separate it from the sediment layer. A lot of blocked washing machine filters and dirty cisterns are traced back to submersible pumps not being isolated from the sediment layer and in most instances, this also contravenes the manufacturer's instructions and conditions of warranty. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ The white 20 mm uPVC pressure pipe, if installed in direct sunlight, is required by AS/NZS 2032 to be either painted with light coloured water-based paints or otherwise protected. It hasn’t been but the uPVC downpipes are also unpainted and so this could be planned to be done later. As per the photo, it is currently not compliant. There are 4 tanks yet they haven’t used a settling tank system. Big mistake but this is a matter of best practice and knowledge which isn't covered by compliance. I am interested as to where the gutter’s high and low points are as I somewhat doubt that there would be a high point between the downpipes. I would have had the left side downpipe draining to the second tank from the left. It is more than possible that the left downpipe harvests the greater roof area but the overflow pipe is on the tank at the other end! This could easily cause the left hand tank to over-top during heavy rain once the tank fills as the inflow could easily exceed the flow capacity through the tanks balance pipes. Unfortunately, the photos don't show the position and size of the balance pipes. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: Coral Homes' Daydream 32 in Kurri Kurri NSW 258Jun 26, 2015 10:34 pm Not much happened this week the carpet went in and the house was cleaned professionally (but the outside still looks like a dump so hopefully that's Monday's job). We are still waiting on a few things on back order including the outdoor kitchen bench, sink and grill, the triple sliding doors for our study cupboard, the shower in the main bathroom and the bigger shower screen for the ensuite. Our PCI is booked for Tuesday at 9am. Hopefully my night shift goes well Monday night and I can get out of the hospital on time (winter brings in more sick people for obvious reasons) and get home by 9!! Then it should be 7-10days and we can FINALLY move in Our fences start on Monday, our blinds have been ordered (roller for most of them, panel for the sliding doors), 3/4 of our furniture is purchased and I have started packing too! Bring on the next two weeks! Media room step and carpet Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Our black carpets are in all rooms - media, four bedrooms and the study.

We're supposed to have PCI on Tuesday too! Not sure what we're still missing though. Ask the council if there is a chance of getting build over easement exemption. Sometimes easements are unused and 24cm is not all that much. Good luck.
