This blog post is about plumbing in New Zealand and includes information about the plumbing needed for a residential house, why you might need to use a plumber, how you find one and where you look. This is a domestic rather than commercial context.
The owner of a house needs a plumber for three main reasons – the first when building a house, the second when doing alterations and the third for repairs when something goes wrong.
A plumber is a trades person who is certified to do plumbing and often gas fitting. They gain plumbing qualifications, usually at a polytechnic – doing a course that has practical sessions. These qualifications are usually Level 4-5 certificates under the New Zealand Qualification authority.
A person wanting to become a plumber learns the plumbing trade by studying the plumbing course and being an apprentice to a certified Master or registered plumber. As the apprentice, they observe the plumber carrying out his trade and is supervised until he becomes competent by gaining the Plumbing certificate and can successfully complete plumbing tasks.
The apprentice needs to learn how to use the tools of his trade, buy his own and know how to look after, maintain and service his tools and equipment. The first course the apprentice needed was to learn about how to work safely in confined spaces, followed by how to work at heights. His first aid covered the first aid equipment he needed to take with him on the job and how to avoid accidents by working safely.
Joe Stephens is one of the best local plumbers Whangarei has who only takes residential housing plumbing jobs. He is one of the best plumbers Whangarei has ever seen. In January 2017, he had a job to fix a shower leak in a bathroom. First he spoke to the owner as to what the problem was. The owner said that the shower was going very slowly and was leaking around the shower faucet.
The plumber turned on the shower faucet and watched the water flow and observed the drips when turned off. He used his plumbing tools in his kit to unscrew the shower faucet, take out the valve with his wrench and turn the screw inside the pipe. He need to cut a hole in the shower cubicle to gain access to the pipes. He found that the pipe needed some glue around the fitting to make it water tight.
He showed the apprentice how to install the water holt water pressure valve before installing the water pump. He explained that the hot water pipe expanded and contracted as it got hot and cold. The temperature control valves were then installed and tested while following instructions in the leaflet, plumbing procedures and according to local council regulations.
He used other plumbing tools to measure the length of the water pipes he needed and then to install the appropriate fixtures to other pipe. He did this then attached it to the other pipe and completed the maintenance by filling up the hole in the shower cubicle.
The following week, another call came when the person was installing a dishwasher in a newly renovated Kitchen and needed it fitted with the appropriate plumbing outlets for the water. There was a hole in the back of the wall under the kitchen bench where he needed to fit a series of pipes for hot and cold water so it went from the dishwasher unit to the water outlet.
