I saw corporate_misfit's pump with the variable speed controller and 35l pressure tank this week and when it comes on, it is so smooth and quiet compared to the pump…

Yes, please send me his details. I think it would be worthwhile to know more about his set-up as a pressure tank is definitely a part of my plan and…

Thanks for your detailed responses SaveH2O, they are really helping me to understand what is involved. The information you have shared should be invaluable for anyone trying to work out…

Just going through a small redesign at the moment but it should have no major impact on the plans so far. I was just wondering what would be a appropriate…

I don't know why they are using the same table for both countries as it seems that it would give a big buffer the for NZ homes.
The NZ figures for…

That is a big gutter
Yes, it's a big gutter It is really aimed at more commercial applications but I think it will…

Thanks for the education SaveH20, it is really appreciated. I am learning quite a lot. After thinking about it properly, I realised my error with the idea of lowering the…

If I installed a backflow prevention valve in the line to the tank could I then lower the installed height of the leaf diverters and FFD's to be near the…

Thanks again for all your help SaveH2O, it is really gratefully received.
They sent me the spec drawings for the tanks and that is the rim height from the drawing.…

Just to clarify, I wouldn't be burying the tanks as the ground is falling away beside the house and it will just require a couple of small cuts to create…

Thanks for the link SaveH2O. I have been revisiting the house design and am now looking at going with a suspended floor so minimal cut and fill involved for the…

I have had a quick look…

I have calculated out the monthly mean rainfall adjusted for an 1100mm average yearly rainfall at 60% yield on 292.6sqm of roof. If the average daily consumption for 3 people…

6 weeks of 529l per day is 22,218l for the reserve. Yes, I know that is not necessarily 6 weeks of actual consumption but the way I see it, it…

Looking at my roof area of 211sqm + 81.6sqm I have a total roof area of 292.6sqm. Multiplying by 1100mm a year rainfall and a 60% yield I end up…

I found a study (2004) on residential rainwater usage in the Auckland region that outlines the following:

Hi SaveH2O, what an amazing response! I am currently trying to absorb it all and read the other threads you highlighted. Yes, I have read some other threads here which…

I am looking at a build in NZ in a semi-rural area where the only service to the property is power so I will need to deal with rainwater for…

Thanks for the info, didn't mean to hijack someone's thread. I think I might need to start a new thread as I see a number of questions in my future.

So much great information here. I read with interest about putting a header tank in the roof space to feed the toilet cisterns to save the pump and I was…
