hello jrmurdock, you have created more questions than answers!

Are you a currently licenced certifying plumber? if not you should not be touching sanitary plumbing.

what was your issue with the plumber you employed?
these 2 questions are a good start.

regards

LOL       



pop into mitre 10 mega and ask to talk to stan - he will see you right old mate

The legal side of things are interesting....

First off i think there are a lot of Myths out there.

For COC:

At the time of the pre‐line/plumbing inspection, the certifying plumber who undertook the plumbing work shall provide the building inspector with a completed (Construction Statement ‐ Pipework Test) form.

As the mess/pre-line was done by the plumber, hence I have the pipework test completed.

Even if I had done all the plumbing work myself, all that would be required is to get a plumber to:

NZBC G12 VM1, AS/NZS 3500.1:2003:  By pressurising the pipework to 1500 kpa for a period of not less than 30 minutes and checking to see that there are no leaks

That's it.... the plumber doesn't need to sign his life away or warranty the work in any way.... he just needs to do a simple pressure test!

NZBC counts for didly - read the governing act

LOL integrated, you must be like the plumber I employed. Unable to give an actual answer to the question, yet able to offer some bung legal advice on the side.

For your reference COC / "certificate of compliance" is compliance with the NZBC. It has nothing to do with your "governing act"

Yes Yes Yes Integrated. Most Plumbers would know the reasons why they position wingbacks at the height and depth that they do such as a preference to use barrel nipples and flanges, to keep connections where they are easily accessible no hidden behind a commercial sink where they are hard to get at, in case some verticalled challenged people take residence in the property and want to lower the sink.

Welcome to our world jrmurdoch where the regulations are as twisted as the people writing and imposing them, where most people think it's just a matter of doing a couple of connections and turning on the water but forget about cross connections, siphoning and other issues that could contaminate a towns water supply. Where you can read on bit of legislation and it will tell you one thing and read another and it is interpreted different.

For example jrmurdoch changing a toilet seat is sanitary plumbing where if must be done by a registered tradesperson and if that person is only licensed then they must be supervised by a Certifying Plumber. You can't blame the tradespeople as we don't make the rules we just abide by them the same as everyone else should.

As far as price goes if you got it done for less that $120.00 an hour you got a good deal.

 

  well said Rodza and to follow I hope the insurance knock back your claim on the damages jmurdoch as that would be the perfect icing on the cake 

I'm not sure why the plumber should have turned up with his own plan? that should have been given to him by YOU!

We do over 100 houses a year and our kitchen wingbacks are all at 600mm off the floor....sometimes you need to extend the flexi hoses....sometimes not....

but I'm sure if you look out your window you'll see the world isn't ending...stop being tight...

as for the depth.....installing 100mm dux (or whatever is your preference) male wingbacks is the best way (no threaded joint in the wall) and the dwangs set back at 35mm from the front of the framing edge....hope this helps
