Second question: DWV tees are a bit different to stormwater tees in that they don't communicate with the carrier pipe at 90 degrees. You have plenty of head and so just keep it simple. I'm having trouble uploading a photo of a DWV tee, will try again later in the morning. Will also post more information later today as I will have a bit of spare time then. Plumbing Sales are close to me and I have often bought various items from them. Many items are sold in small bulk lots which can be a problem for some customers. Their prices are very good and the $19.90 flat rate postage is cheap for most orders. Irrigation stores are usually the best option. Bunnings have become very expensive lately. 3in1 Supadiverta.

Re: Downspouts and Subsurface pipe sizes 22May 29, 2023 1:13 pm OK I'll retain the status quo for downspouts. For the dwv junctions/tees I'm not really concerned with whether it's the wyes or tees etc. It's just that there aren't any tees or wyes in 80mm which is what the majority of my carrier pipe will be. So I can. Either up size to 100mm or downsize to 65mm at the junctions. This is OK with me but I just don't know which is better. Re: Downspouts and Subsurface pipe sizes 23May 29, 2023 5:11 pm 80mm DWV fittings are made in 88 and 45 degree junctions as well as a 45 degree junction with a 50mm branch. Do you have any irrigation store nearby? Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ https://www.perthirrigation.com.au/subc ... V+FITTINGS 80mm pipe and fittings are however more expensive than 100mm pipe and fittings. You could change from having 80mm pipe to 100mm pipe and have sediment traps a metre or so past the elbow at S2 and a couple of metres past the elbow out from DP9 on the straight run. 3in1 Supadiverta.

Re: Downspouts and Subsurface pipe sizes 24May 30, 2023 10:04 pm OK great this is very helpful. I can't find any irrigation stores on the Sunshine Coast that also sell DWV stuff, esp the 80mm for whatever reason that is harder to find. I'm gonna order some pieces as I'm away at the moment but when I'm back I will post some photos of the pads I've built and what I'm planning on doing. I'll be back home in a couple of weeks. Re: Downspouts and Subsurface pipe sizes 25May 31, 2023 5:09 am Ok. I'll ask around and also post some additional notes in the interim. Possibly some irrigation stores further west. 3in1 Supadiverta.

Re: Downspouts and Subsurface pipe sizes 27Jul 17, 2023 7:13 am OK it's been a little while! I've been busy getting time where I can to work on this. I started by grading a pad (borrowing a friends excavator) to place my two crusher dust pads on top for the 2 tanks. I then ripped some H4 sleepers to give me a frame for my crusher dust to sit in. You don't need the frame but since my space was a bit tight, I was worried about errosion at the edge of the tank base. Plus it looks nicer anyways. I spent a whole day making sure my frame was level and staked it into the ground so I could screed the crusher dust to get it flat using one of the off cuts from the sleepers and compacted it with a rental from Kennards. I got my neighbours to help me get the 2 tanks into place and I used builders film at the base (was hoping it would stop scratching the tanks and also stop the tanks digging into the rocks as we moved them around).

Unfortuantely my house has 4 inches of concrete pathway at a lot of the perimeter so I after a bit of research I rented a core drill to get through the slab so that each new downspout addition to the system can be routed underground. Once I drilled the holes, I then used a technique called water boring, which I tackled using a pressure washer, sledgehammer and some hard yakka to get my pipes underneath the concrete toward the holes I drilled. Probably one of the worst jobs I've ever done, especially as I ran into a lot of roots and had to either re bore or try and chop them out with a long fence bar. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ I'm now trying to work out how to get from 150mm DWV to a 50mm low restriction inlet to the tank. I bought this which says it's Clearpond Pondflex: https://smart-water.com.au/product/corr ... -25mm-x-1m Though it's black on the website, they sent me a grey one, is that meant for chemicals and gasses or can I use it for potable water? Should I also use this for the balance line?
