Re: Damp proof course 77Mar 01, 2014 11:46 am Liliana So it's the amount of regrind that determines its strength or lack of. To a degree. Using regrind (same material) makes the manufacturing cheaper. Storm water pipe is cheap because it uses less material (thinner walls) and more regrind. The three pipes are different otherwise. The different classes (pressure rating) of uPVC pressure pipe depends on the wall thickness. uPVC DWV and storm water pipe is not pressure rated. Sorry for the confusion. Liliana I've had a look at 2.4 of the Stormwater drainage requirements of the BCA you sent so I can at least insist on Class 6 UPVC. The document I sent you is not a BCA document, it is an old (June 2006) document from a building consultancy group and it claims to present: STORM WATER DRAINAGE REQUIREMENTS– DOMESTIC PROJECTS (BCA Parts 3.1.2 and 3.5.2) Some of the clauses are now redundant or have been changed, I don't have the BCA regulations and so I can't comment further on the document's current accuracy. I am sure that one of the forum's building inspectors or builders will have a current copy and can comment further. http://www.agbc.com.au/forms/STORMWATER ... EMENTS.pdf I drew attention to 2.4 because it states: 2.4 Storm water drains shall be minimum 90mm Class 6 UPVC and have a minimum fall of 1:100 and 100 mm cover under soil and paved areas; The notable thing is that it states 90mm Class 6 UPVC. Class 6 is uPVC pressure pipe. If for some reason there is another 'Class 6' reference floating around somewhere in our parallel universes in relation to storm water pipe, I have never seen it. If there are two (or three) different 'Class 6' ratings to two (or three) different uPVC pipes, it would be an incredulous situation. uPVC pressure pipe is not made in 90 mm. Either the building consultancy group has wrongly copied the BCA text when preparing the document I sent or the BCA wrongly referred to 90 mm storm water pipe as class 6 at the time the building consultancy group's document was prepared. If so, it may still do so. If the latter is the case, then this is most probably where your building designer has copied it from. Whatever the situation, it shows either a woeful lack of industry knowledge by more than one party or an incredibly incompetent situation where there are references to at least two different class sixes pertaining to different uPVC pipes but such a situation existing is unfathomable. Unfortunately, I don't think that it will help your situation, it is more for 'added interest'. EDIT: Linked the document discussed. 3in1 Supadiverta.

Re: Damp proof course 78Mar 01, 2014 1:26 pm Well if even building consultancies get it wrong, what hope do I have? I've scraped some more dirt away but still can't see any writing. This is the one they used near the rainwater tank though:
Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ I notice it does only have a thickness of 1.9. So can I stipulate the wall thickness I want? Re: Damp proof course 79Mar 01, 2014 1:38 pm It has to be in the contract. The plumbers are highly unlikely to pay extra for stronger pipe as already indicated. The designer botched it. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

Re: Damp proof course 80Mar 01, 2014 1:41 pm I've just looked back through my correspondence with the builder and I have found this: The main pipe (discharge pipe) that runs to the front is 100mm. Me: I understand that the discharge pipe is 100mm but what about the pipe feeding the rainwater tank underground? The plumber advised it's 100 mm as well. So that is clearly not true as far as this particular pipe is concerned anyway. Have look at your house plans and you will probably find that brick articulation joint has been missed.
