I started designing and prototyping a superior leaf diverter in April 2015 but had to shelve it in September 2015 because the 500-micron filter, which had unique flow paths, could…

Don't underestimate the importance of also having a forensic examination at PCI of all stormwater and sewer pipes plus the roof drainage for compliance. A plumber's COC is self issued…

No one is going to come knocking on your door, check your house for roof drainage compliance and fine you if errant.
Plumbing practicioners in Victoria are required to install roof…

Hi Stacey,
It's always great to hear reviews of the implementation of advice given on the forum. I wish they happened more frequently.
As you will have found, doing something to…

The timer sounds amazing! I might buy one and do a long-term field trial.
Why can't you attach the timer to a tap supplied by a pump? The pump will turn…

All said and done, the only difference between the gravity fed drip tube that you previously used and a standard drip hose that requires a 100 kPa pressure regulator is…

A recent customer bought that and removed it, saying it needed more hydraulic head than he had available.
Just checked the specifications and it states a minimum 40 kPa.

Ah, I see.
The high AusPost charges are the problem, particularly to QLD. I have a Sendle account and so I could check their freight cost but it would be…

I sell the only Holman Green Smart gravity drip hoses available in Australia (but only sell in the Melbourne metro area) and I have been told by customers that the…

Ok, thanks. I had to make absolutely sure.
Given that a substantial part of the pipe run will be dry even when the tank is full and also considering the cost…

In post 6, you wrote "There is an approximately 1.5-2M drop in height from the last downpipe to the top of the tanks." Is this drop from the top of…

Excellent.
You are better off having a floating intake made for you by an irrigation store. The commercial ones are overpriced, the 'filter' often has large apertures (1200-1400 micron are not…

Just join three 45-degree elbows together but you need to have water diverting into a tank to first pass through mosquito proof mesh. This would be satisfied by fitting good…

So, two 225mm pipes each diverting water from 450 sq m of roof to separate tanks.
A 150mm DWV pipe has an internal diameter of 146mm. This equates to a volume…

Before I give a full answer, I need to know the harvested roof area and your 1:20 ARI/AEP.

Shouldst thou direct thy cursorem o'er thine avatar, a window shalt forthwith appear. Within, at its lowermost part, is found the means by which thou mayst log out.

There is discussion about fitting a low restriction inlet in many Homeone threads. Just do a forum search using the keywords.
It is simply a tank valve with a flexible hose…

I just noticed that I wrote "overflow" instead of inflow. I have edited it.

Are you off the water grid?
The amount of water that is lost is considerable and the leaf diverter's overflow characteristic is weird. I also don't understand why the upstream leaf…

If I am understanding what you have done, the change will make little difference because the height of the water column hasn't changed. Most friction loss will occur at the…

Here is a similar one except that this one overtops (insufficient hydraulic head) whereas yours pushes water forwards which indicates that the bottom of your upper downpipe is angled to…

When you check how far below the leaf diverter the standing water is, can you also do a comparison check with the other downpipes that divert into the same carrier…

If it isn't a head issue, it will invariably be a blockage. Given that it isn't the furthest downpipe from the tank on the carrier pipe, the blockage has to…

Are leaf diverters fitted to all downpipes and are they all at the same level?
Is the problem leaf diverter (shown) the one that is furthest from the house?
When it…

Should thou wish to keep thy palate sweet for sausages, avert thine eyes from their crafting.
Bunnings sell the adaptor.
Algae needs light and nutrients to exist. Having well designed leaf diverters…

Oh, it's vertical and bell-mouthed! Its overflow capacity will be massive plus the vertical extension provides more storage capacity.

The ICON adapter is very small when compared to standard 100x50x90mm adaptors and so there are less beads used in its manufacture and packaging and freight costs are a lot…
