Re: Stormwater pipes and primer 28Feb 19, 2016 7:18 pm Primer is essential to prepare pipe walls for joining. It will remove any pipe manufacturing residue that may interfere with fusion of surfaces of spiggot and socket. Over the years I have seen few joints fail and have in some cases been able to recover fittings for re joining. However where solvent cleaner is used reclamation is impossible because of fused surfaces.

My concreters unearthed my aggi drain that is supposed to discharge to a silt pit as per engineering. It must also discharge to a silt pit as per the regulations found in: AS/NZS 3500.3 AS/NZS 3500.5 Just a very important note here about AS/NZS 3500.3 and AS/NZS 3500.5 The National Construction Code (NCC) comprises the Building Code of Australia (BCA) Parts 1 and 2 and the Plumbing Code of Australia (PCA) Part 3. The BCA has hierarchy over the Australian Standards that are called up in the BCA as Deemed To Satisfy (DTS) solutions. See hierarchy pyramid below. The BCA sits at level 3, the Australian Standards sit at level 4a as DTS provisions. The Plumbing Regulations 2008 adopted the PCA in 2008. The PCA at the time of adoption (2004 edition) made no reference to the BCA under the DTS provision for roof drainage systems. On May 1 2011, the PCA was introduced into the NCC as volume 3.At the time of adoption, Victoria introduced a variation into the DTS provisions of Part D1 to exclude the BCA as a DTS provision for roof drainage systems. Victoria has made no changes to the variation in Part D1 of the PCA since it was introduced in 2011. Because you are building in Victoria, if you or someone else representing you argues any case regarding stormwater drainage (which includes roof drainage), you only need to refer to: AS/NZS 3500.3 AS/NZS 3500.5 To put it politely, the BCA was excluded because the BCA roof drainage regulations are crapola! However, having said that, the AS stormwater regulations also promote sub standard installations (pipework that is insufficiently sized in many instances to facilitate the roof area drained) because plumbers are judged as qualified to install to their own 'design' which they are then able to sign off as being compliant. Lol. Even if your builder is also a plumber who is qualified to do stormwater drainage, diverting Ag pipe directly to the stormwater system is a big NO. If he is not a suitably qualified plumber, then he should not have done the installation and if the work has been signed off by a plumber, then he should also be hauled over the coals. 3in1 Supadiverta.

Lol. Yes my builder pulled that one on me. They under designed my stormwater discharge system and claimed they complied to AS. When questioning how they pulled the section which says they can use their experience and knowledge of the are to design the system. I'm planning on making a complaint to the plumbing board of they do not fix it. Re: Stormwater pipes and primer 32Feb 20, 2016 7:15 am I did find a reference in the Standards where AS2200 is needed to be consulted when calculating the pipe sizes...I haven't been to bed yet but when I get a chance this weekend, I will find the reference and post the details for you. The Victorian Plumbing Commission was abolished several years ago, plumbing now comes under the VBA. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.
