Browse Forums Building Standards; Getting It Right! 1 Jan 31, 2022 2:11 pm Hi brains trust. Im think i may have a plumbing fail on my hands and would appreciate an opinion from some of the qualified blumbing professionals on here. I aske dthe builder to ensure the plumber took pics of the clay plugs an dthe installed flexi/swivels joins. What i got back was nothing that shows that these were installed. House is on H2 soil and the below excerpts from the plans are noted for dainage.

Re: possible plumbing fail on new build 7Jan 31, 2022 7:11 pm Whatever is in the contract or engineering plans apply but I don't think that the plumber would have appreciated being asked to take photos. You have to be careful about AS 2870 because the NCC only references it for the slab which comes under building/construction, plumbing is not referenced. It is critical that the plumbing provisions are legally referenced elsewhere. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

You have to be careful about AS 2870 because the NCC only references it for the slab which comes under building/construction, plumbing is not referenced. It is critical that the plumbing provisions are legally referenced elsewhere. To be fair, whether the plumber was pleased or not is of little consequence. They're self certifying work that has zero ability to verified after the slab goes down. We've seen in this forum and in the Induistry what happens when no one Sks questions or verifies the work. What I'm trying to understand is from the pictures provided, is whether there appear to be are any flexible/swivel joints installed (as per the documented plumbing requirments),as to me, they appear to be missing wholesale from the entire job so far Dark matter scientist, can breathe underwater, mind reader and can freeze matter just by willing it.

Re: possible plumbing fail on new build 9Jan 31, 2022 8:28 pm Here are some details, others have put photos up before similar to this Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: possible plumbing fail on new build 10Jan 31, 2022 8:43 pm I have plenty of diagrams. And I understand how it's supposed to work. Im asking whether the photos appear to show any of these joints in place? I'm not a plumber, but to me it appears they arent installed in any of the pics. Would there not need to be expansion joints in the upvc pipes penetrating the top of the slab where they enter the home? The expansion joins are detailed in the plans for down pipe connections and logically if there is movement would ntthe pipes penetrating into the homes also be subject to those pressures?

Also there aren't any penetrating edge beams, but the highlighted dot point in pic 1 is the scenario I'm asking about Would there not need to be expansion joints in the upvc pipes penetrating the top of the slab where they enter the home?

Re: possible plumbing fail on new build 12Jan 31, 2022 9:36 pm The detail I've put up illustrates what you have highlighted in yellow It's pretty clear? Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: possible plumbing fail on new build 13Jan 31, 2022 9:37 pm I can't see any couplings or swivel joints from what I see. They are very apparent when fitted. Clay plugs can be compacted clay soil that is yet to be laid but there are also clay plugs similar to boxes made by companies like Plastec, These are very noticable. Look up Plastec and search for Clay Plug. Storm Plastics might also make them. Were the photos you posted taken by the plumber? I don't understand why he wouldn't fit swivel joints etc if he knew he was to be taking photos. Are the pipes now covered? If not, can you visit with the builder or at least contact him? 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

Re: possible plumbing fail on new build 15Jan 31, 2022 10:22 pm The photos were taken weeks ago by plumber, only tendered now. Deck is in place with pour tomorrow. I've raised concerns earlier today. Familiar with clay plugs, though with how much gravel there is either side of the pipes its hard to say they've installed them either. Plumber recons he has. Short of pulling up the formwork and digging, won't be able to tell for sure. I wondered why he'd sent these like this too, which is why I was questioning whether I was missing something. Are the swivel/expanders also meant to be on the plumbing coming up through the slab into the house? That's how I read the hilighted requirement.

The Footings and Slab were inspected independently as will the rest of the work throughout the build. The pour was delayed to resolve the defects associated with the Slab and photo evidence received of rectification. The problem is not the slab/footings, it's the plumbing. Underground. Which a slab/footings inspection doesn't pick up nor is it the engineers remit. The plumbing, as you well know, is self certified by the plumber. The surveyor doesnt even sign it off. So there's nothing an engineer conducting a Slab Inspection is going to be able to comment on in relation to what I'm asking about UNLESS the plumbing was protruding through an edge beam which would be visible in the form work.

While it won't help with regards to clay plugs surely a snake camera inspection of the plumbing would show the flexible joints if they were installed?

I get one of those as standard at handover to ensure the system isn't damaged. But I've seen how the footage of these these inspections generally looks and Im not confident it would be able to pick this up. The pull through is generaly too fast to spot joins and other minor visual indicators and is primarily dne to spot any crushed pipes or errant star pickets through the system etc. Dark matter scientist, can breathe underwater, mind reader and can freeze matter just by willing it.

LOL, Of course not it's always someone else's problem even when they overlap most on site never look past their noses, until someone points out a problem. Builders are great at instructing their certifiers to look at only what I'm paying you to do... so look the other way...and don't trip over (humour) Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs yes it is possible but watch for noise transmission, decouple as best you can.
