Months have dragged by, but finally an update. After 13 rejections, a plumber was booked, but was a no show for 12 weeks. Eventually found another who turned up. Even better, he read all the instructions on the box for the SupaDiverta, and got some understanding about vortices.
Not everything has been fully done as planned as there's still a lot of other work in progress, and as usual, everyone turns up at the same time. The major omission for now is not connecting the First Flush fittings to the SupaDivertas. An interim simpler solution was to run poly down to a tap valve, which then fed into larger poly, ending at the drainage pit near the tank.
Like the majority of other aspects of the overall project, very little has gone to plan or budget.
garage side shows the start of the lines to the tank, and the Metric Poly exiting the pump and filters toward the house.
The old system on Imperial poly still feeds inline to the house, but with backflow valves the new system will be enabled by a valve at the pump, and the old system pump being switched off.
Gutter was installed after these photos. Unfortunately the roof plumber went on 4 weeks holiday, so missed out on 125mm in 2 days!
It was a bit of a juggle with all the pipes.
90mm Stormwater goes to the right and meets the existing house system feeding the old tanks.
There are 2 more downpipes and SupaDivertas along the Shed wall.
note. to smooth the flow into the 40mm PVC, 45º elbows were used. The T into the 40mmm pipe was rotated at 45º, saving another adapter..
transit from shed under path to tank.
Unfortunately I was elsewhere when the Sediment Trap was done, and think the rise before it may affect it's performance.
Tank Connections. not shown around to the left is the CFA outlet.
The PondFlex and 40mm connections hopefully are the gentle rise, though there's a 90º elbow at the input.
at ground level is an incorrectly installed 20mm outlet, but with a valve installed if ever needed.
The mid level outlet is 32mm Metric. alongside another incorrectly installed 25mm outlet, again with a valve fitted in case of need.
A Grundfos constant pressure pump was a bit of a splurge, but with the old Davey dipping around 5 times in a 5 minute shower, it was deemed essential. Probably not really required, water filters were also installed.
The catchment is all new and Fielders mesh will be installed, and the closest trees taller than the building are 50 metres away.
Nothing in the tank as yet, until more rain comes along, though the first few times will be used to wash out the various lines.
Still many other elements of the refurb and new building to be done, so First Flush and other corrections that may be suggested will be looked at when it can be fitted in, if there's anything at all left in the budget bucket.
None of this would have happened without the considerable help, advice and patience of saveH2o. I've tried to understand the concepts, and hope we've come somewhere close to practical completion.
