We specialise in plumbing, drainlaying and gasfitting. Our capability to take care of all plumbing aspects of the build results in a smoothly run project. Our office liaises with your builder or project manager to coordinate the work and our capable plumbers get the job done. If you are project managing your own build, we can advise you on a plumbing schedule and our requirements at each stage.

PLUMBING

WHAT'S INVOLVED

Water and waste pipework e.g. for bathroom, kitchen and laundry​. Plumbing is installed in three main stages; preslab, preline and fit off. Preslab refers to the pipework laid beneath the slab. Preline is the pipework brought up through the walls. Fit off is the installation of your front of wall fixtures and fittings.

PROJECT STAGE

Stage 1 - Preslab​ (after foundations, prior to slab being poured)

Stage 2 - Preline (after roof is installed, prior to insulation going in)

Stage 3 - Fit Off (after painting/flooring is finished)

USEFUL INFORMATION
  • Each stage of your plumbing will require a council inspection which we will organise on your behalf. 

  • Central heating pipework and fittings are installed at the same time as the plumbing stages.

GASFITTING

WHAT'S INVOLVED

Gas pipework and appliance installations for water heating, room heating and cooking  e.g. gas fire, gas hobs, 

PROJECT STAGE

Stage 2 - Preline (after roof is installed, prior to insulation going in)

Stage 3 - Fit Off (after painting/flooring is finished)

USEFUL INFORMATION
  • Council require a gas certificate to submit with your code of compliance which we supply as part of your final documentation.

  • Most properties in Wanaka and Queenstown have LPG bottles rather than natural reticulated mains gas. We install an external gas bottle station with 2 x 45kg bottles.

  • The gas bottle station must be installed on a concrete pad on flat ground, away from windows and any sources of ignition e.g. external water heater.

  • Reticulated mains gas is only available in newer subdivisions. The home owner liaises with the mains gas provider to get a meter installed by an appointed third party.

DRAINLAYING & MAINS WATER
WHAT'S INVOLVED

Drainlaying refers to underground external wastewater pipework, water mains, stormwater pipework, soakpits, sumps, downpipes and channel drains.

PROJECT STAGE

Stage 1 or 3: Drainage is preferably done after the slab is poured, prior to scaffold going up. If this isn't possible, the drainage will be done at the end of the project, before landscaping starts. 

USEFUL INFORMATION
  • External drainage requires a council inspection, which we organise on your behalf.

  • Council require a drainage plan to submit with your code of compliance which we supply as part of your final documentation. 

OFF MAINS SOLUTIONS

 

WHAT'S INVOLVED

We can assist with off mains solutions for semi-rural/rural properties  e.g. water pumps, water tanks for rainwater or fire-fighting, onsite wastewater treatment and disposal, irrigation dripperfields. 

PROJECT STAGE

Stage 1 or 3: Usually coordinated with other digger work as excavation is required. 

USEFUL INFORMATION
  • An electrician must be engaged for pump installations. 

  • An wastewater engineer must be engaged for onsite wastewater dispersal. We then install the system according to their specifications. 

  • Most water tanks in rural residential areas require a fire-fighting connection.
