Before you consider the type of path, you must first consider your soil classification.

This is a very common problem and the reason why a lot of people don't fit leaf diverters to the top of wet system downpipes. If at all possible, they should be fitted to prevent mosquitoes and other pests accessing the standing water. Your wet (charged) downpipe diversion will discharge into the t...

Like with any builder, you need to check the contract for 'hidden' Performance Solutions '. Henly had one a while ago that allowed for a 20mm recess for the Damp Proof Course . Many new home owners have not even heard of Performance Solutions and remain forever none the wiser. There are many Perform...

An additional fact that you need to know to understand the system is that the friction loss expressed as equivalent pipe length of the pipe between the pit and the intersecting junction is about 46m. A 250 mm water level above the pipe's invert in the pit will provide a maximum flow rate of about 39...

I should have enlarged the photo that showed the pit's pipe, that would have shown me that it wasn't a thin (1.9mm) walled 90mm stormwater pipe. Aah! The perils of not being on site. https://forum.homeone.com.au/u/38282_1555036604.jpg It looks like water could seep through around the pipe. I would ...

Just wondering instead of connecting the watertank overflow pipe to the stormwater pipe, just connect that to the Pit (probably increase the size of the pit). Or use a 2nd pit for the watertank overflow pipe and then to the stormwater pipe? The tank is part of the stormwater system and it also need...

Lol, they state free Standards but charge when someone falls for the click bait. I'm glad that you were successful elsewhere.

Thanks for the diagram, exactly what I needed. I can see the problem, it's what I suspected and it fails to meet the performance requirements in the NCC by a huge margin. Whoever did the storm water plan has no clue about hydraulic design. I will post some calculations for you tomorrow when I have t...

So you have to get out of your sleeping bag in the dark, scrounge around for a weapon, you find a thong and beat the bejesus out of it! G'day to all of our American friends out there.

Except that you could have stayed in the Penthouse Suite at the Grand Hyatt Cannes Hotel, Martinez, France and had change left.

I don't know where you stand with the builder, it's not my field. It appears that the slab (and site cut) is too low, did you have the house built or buy established? An inadequate head is effectively a flow restriction and the one I was fearing you had. 1. Does the pit connect to a common pipe that...

Is that ORG? . The round with the black grate. I thought its just a storm water inspection point. Thanks for that....You are correct of course. I should have looked closer, I thought that it was domed. Not an ORG!!!

Yes, I heard about this on 3AW talk back radio. Unfortunately, legislation deems it necessary.

I contacted a plumber when I noticed it with the recent rain. I think he is just everyday plumber. I was given a quote of around $8000-$9000 to put AG around the 3 sides of the house. Considering this is $$$$ expense, I thought of getting another quote. https://forum.homeone.com.au/u/88799_15545985...

We recently bought a house which is around 2 years old (NSW, Liverpool Area). We are in a difficult situation with drainage. Our house sites at a lower level than our neighbors.The soil is reactive (H1) clay so water doesn't drain easily. We are planning to put AG-pipe so that the water drains prop...

whom to blame... Metronest Homes, GD design & his engineer, Surveyor, site supervisor, trades people, or colour consultant team, estimator team, or Owner of our builder. No one bother to come forward & except thier mistakes. Everyone blame everyone. https://forum.homeone.com.au/u/38282_1554...

You need to use a proper thread title when you start a thread seeking advice because it will also helps others later when they do a forum key word search. I will answer your question after you have edited the thread's title to something that will also help others.

KDR sites ideally should be subjected to rehydration to predetermined moisture levels. There was a healthy trend towards it a few years ago when some slab engineers started making it a condition. Not sure if any are still doing it but many regions are already in a dry spell and there is a good chanc...
