Plumber Jobs in New Zealand


What does a Plumber do?

A Plumber installs, maintains, and repairs water, gas, sanitation, drainage, air conditioning and roofing systems depending on their area of expertise.

What skills does a Plumber need to have?

The skills required to be a Plumber centre around installation, maintenance and repair processes for the water supply, heating, and sanitation of a building. There are several different types of plumbing including mechanical, sanitary, drainage, maintenance, and roof related services. There are common core and technical skills across each discipline, but there are also specific requirements which are unique to each respective aspect.

Mechanical plumbing involves the installation, maintenance and repair of air conditioning and heating systems. This includes the unit and any necessary piping or duct work. A mechanical Plumber should be able to determine the specifications and dimensions required for installation through interpreting the blueprints of the respective air conditioning or heating system. 

Knowledge of evaporator and condenser coils in air conditioning units is required to complete installation effectively. The same applies to VRV (Variable Refrigerant Volume) or VRF technology (Variable Refrigerant Flow) which are designed to reduce energy consumption. A sufficient understanding of the above ensures that a Plumber can work competently across all systems including ducted, split system and bulkhead units.

Sanitary plumbing related to discharge pipes, sanitary stacks, sewerage pump sets, drainage, and disposal systems. A Sanitary Plumber will also need the acquired knowledge and skills to clear blockages, rough-in water supply and pipes along with install appliances and accessories.

Despite sharing similar elements with sanitary plumbing, drainage plumbing requires additional expertise. This includes being able to install drainage systems both above ground and in-ground, along with connecting stormwater and sanitary drainage systems. Training and certification to use excavation and other machinery is necessary to complete the drainage processes.

A large portion of plumbing work is either installation or repairs, and the importance of ongoing maintenance cannot be underestimated. A Plumber needs to have a certain general knowledge of building and construction. This is useful when clearing blocked drains, dealing with hot water systems and gas maintenance. They are also regularly required to service and replace taps and household appliances including dishwashers and washing machines. Identifying leaks and the source of them is another critical aspect. This is most often related to wet areas such as bathrooms and kitchens.

Plumbing is not limited to drainage systems that run at or below the surface. Those with expertise roofing and gutters are in many cases required to have plumbing qualifications. This covers a wide range of tasks such as cladding, laying roof sheets, capping, and flashing. The installation, maintenance and repair of down pipes and gutters is another key component.
