My interpretation was under ground = drain, above ground = plumbing.

scroll to bottom of page for a link to down load an info brief and i think there definitation is on pg4

this on the pgdb site also defines what is plumbing and drainlaying but as normal the board didnot cover the full story and include slabs in this outline and as most new housing nowdays involves slab work this is a very poor performance from what is ment to be a knowledgable gang of people yet they fail to realise that when plumbers ask them what is drainlaying and what is plumbing...We plumbers are refering to under/in slab drainage when we ask BECAUSE we already know that under ground pipework is drainage and suspended/above ground pipework is plumbing...we already know this but the stupid board doesnot and will not clarfy why below ground pipework under a slab is considered plumbing when in all reality it is drainage in my eyes...i would hesitate to guess that there is no where in the legislation that defines this area of plumbing???drainlaying??? so they will not approach this area for fear of opening a can of worms...imagine if all of a sudden it was found that slab work is actually drainage work there would be court cases flying left and right and fingers pointing in every direction lol.

I hear that in australia the drainlayers do all under slab work as it is rearly drainage and it is actually below ground...again we in NZ are some of the only ones left on the planet who are run by the all powerfull bunch of no common sence dictators at the board who are afraid to clarify with legsliation in hand why actual drainage is called plumbing works???...makes me laugh...lol

Does anyone out there in the big bad world of plumbing know where it defines slab work as plumbing works???...or is this just how it has always been? :P
thanks thunder.

Not saying this is entirely technically correct and true - just that maybe this is the way it has always been
