I assume then that the house is on stumps.

Also not done and he cannot possibly argue that it was for to do so would be to argue even greater incompetence.

Who certified it? It has a 100mm DWV pipe.
If your 1:20 ARI is 265 mm/hr, the velocity of water flowing through a 100mm DWV pipe (104mm ID which has…

Have you checked your contract to see whether there is a Performance Solution that allowed the brickies to use a weaker mortar mix?

45 sq m falls under the 50 sq m column. If you scroll down to the 275mm/h Design rainfall intensity, you come to a B or E gutter which are…

The left side overflow area could be a 100% result of the inadequate gutter size but it is more likely also a result of inadequate slope. Does water pool in…

So...you have no Legal Point Of Discharge (LPOD)?
That is not a good situation when you are on reactive soil plus the 'pit' is too small and would quickly swamp. You…

That is correct and it is something that I have posted many times to point out the absurdity of the reg. Suitably sloping such a gutter would result in a…

This is going up on my Wall Of Infamy.
BTW, NCC Volume 2 3.5.3.5 states:
"Downpipes must -
(a) not serve more than 12 m of gutter length for each downpipe".

I couldn't make sense of this the first few times that I read it but I now suspect that he was possibly/probably referring to the pipe flowing with reverse slope…

I"ll address your concerns as a segmented block answer and also try to explain and reference the regulations so that you understand them. I cannot however help addressing the answer…

Do you know the gutter size and are there overflow slots in the front wall? I need to know the gutter's cross sectional area to check compliance.
How old would the…

A few more mentions about the diagram.
The 300mm gap requirement shown between the bottom of the pipe at the top of the vertical riser and the leaf diverter (rainhead) is…

You need to check the QLD plumbing regulations but here in Victoria a COC is issued for plumbing work when the total value of the labour PLUS parts and fittings…

This should be compulsory for every State as it is in QLD and most if not all other northern regions.

Yes you can but having a container that can hold 1,000 kg (1 ton) of water sitting in your attic is a different matter, something you should get professional advice…

The cowboy has done work that is massively non compliant and you should take steps to get your money back and additional monetary compensation for removing the defective work.

Ag pipes have to be connected to silt pits. That is a regulation.
The pit's drain pipe is then usually connected to the stormwater by a licensed plumber but it can…

Is this still to do with housing? It looks like it is off a train.

The builder needs to take care to ensure the house is built as per the plan and contract. What is on the plan?

It will be part of the charged system and water in the downpipes will be the same height as the tank's vertical riser. Every 1 meter in a water column…

There are recent similar threads, just do a forum search using appropriate key words.

I assume that the pipe next to it is a vertical riser (inflow) pipe. If so, the capped pipe might be someone's idea of a charged system's inspection opening/flush outlet.…
