What do plumbers do?

Qualified and licensed plumbers provide a range of services relating to plumbing for residential, commercial or industrial properties. It is typically considered the that ‘dirty job that someone else has to do’. Generally most people don’t give a second thought to their plumbing until a problem arises with a leak or blocked drain. The truth is, plumbing is the one system that your home in Sydney that you absolutely can’t be without. It keeps your home clean, hygienic, virus free and safe. It enables you to cook, clean and do many other things we take for granted.  Without plumbing you’d have no hot water, no gas to cook with, no flush for your toilets, no swimming pools or no air conditioning.


Plumbers plan, install, maintain and repair all the systems in your property that allow water and gas to flow in and out. Consider where these systems exist: bathrooms, toilets, kitchens, laundries, swimming pools, barbecues, air conditioners which are in all rooms of your home. What you generally see or experience is the fitting or fixture e.g the toilet, vanity sink, tap etc. Although what you don’t see is the system of piping, valves and fittings that allow these systems to work correctly. These have to be carefully selected, placed and installed inside your building walls by plumbers or gas fitters. Without this your plumbing won’t operate effectively, quietly and in a way that keeps you and your family safe.

Do people who do plumbing need to be licensed?

All of these scenarios and requirements are just a small example of why all plumbing must be done by a licensed plumber in Australia. Trying to take matters into your own hands could lead to disastrous damage to your property, or even injury or death. This becomes even more important in unit blocks or properties with shared walls. Plus on a more practical level it could void any insurance claims.

So yes, a plumber has to be licenced and it is easy to check online for their current license and for a safety certificate.

Why can't you fix or install your own plumbing?

Like many skilled trades there is a lot more to plumbing than meets the eye and a YouTube video won’t provide all the answers to every scenario. Plumbing in Sydney is very carefully regulated in order to keep it safe while also ensuring standards are met, for example;

Sewage and waste – have to be managed carefully in order to avoid the dangers of exposure to harmful bacteria and poisonous gases. 

Natural and LPG gas – is highly combustible and requires special care with procedures to avoid ignition or explosions.

Hot water – regulations also exist to ensure that the water in your hot water tank is of a sufficient temperature to prevent the growth of dangerous legionella bacteria. At the same time, your plumbing also needs to incorporate valves that limit the temperature of the water coming out from your shower, so that it won’t burn your skin

Piping – the materials used, sizing, types of joins and gradients used must meet the correct measurements or falls to not only be legal, but to function correctly.

So while some people may feel like it is possible to replace a washer in their leaking tap themselves or unclog a drain, you may be surprised as to the underlying issues these problems are causing that only a qualified plumber can identify and remedy correctly.
