What’s Involved in Installing New Gas Lines for a Renovation?

Mainline Plumbing andv Civil Pty Ltd Client • September 3, 2025

‘What's that smell?’, ‘Was that a hiss?’, ‘I don’t like the look of that old pipe in the corner’. When you’re renovating a building, you can come across all sorts of unfamiliar and unexpected things, and way up there on the list of worries will be gas, because this is something you know you can’t mess around with.

The good news is that there is no need to worry as long as you have the right level of professional expertise at your disposal, and that means finding a good gas fitting plumber.

What makes a good one? Qualifications is the logical place to start. For a gas pipe installation or a new gas connection in NSW, find yourself a licensed professional. It is easy enough to do this; if someone is a licensed gas plumber they will advertise the fact. It will be on their website, on their ads in the local paper and on the side of their van.

That is because it’s a good thing to be. It’s a skill that involves study and practice, and because gas can be dangerous, knowing how to deal with it makes a gas fitting plumber a sought-after member of the local trades network.

Word of mouth is a great thing too. See if any family or friends have recommendations. This can be very important with any trade but is particularly so with gas.

Why Is Gas Such a Cause for Concern?

Gas is popular for central heating, hot water and particularly cooking because it has this instantaneous quality. You don’t have to wait for things to heat up with gas. Show it a flame or even a spark and it’s away generating heat. Hence the expression ‘now we’re cooking with gas’.

Cooks like it because once you switch it off it is off immediately, too. If a pan of milk is about to boil over, turn off the gas hob and the milk settles down. Do it with electricity and it’s a gradual process, so the hob will cool down in a while, but not before it has sent milk all over the place.

But it’s the ignition that concerns us here. When something as volatile as gas is involved, you have to know where it is – which is particularly important in renovation jobs, but also crucial if your building is going to be the bright young thing on what is now a demolition site. Bulldozers and drills are not subtle.

They get results by sheer power, and while that can be a great help if there are obstacles to overcome, if one of those obstacles is a gas pipe, there can be trouble.

That is why in Australia a group of enterprising people in the construction industry formed Dial Before You Dig, which is now a nationwide resource where developers can check if there are any gas pipes down there before the heavy machinery rolls in.

This is very important for a new gas connection in NSW, because when things are buried, coming across them can be a nasty surprise.

Upgrading Gas Lines

If there is already a gas line into a property, that may save time and money, but not always. If it is not up to current standards, for safety’s sake it will have to be replaced. Technology has moved on and what was good enough fifty years ago may now be regarded as hazardous and, for instance, old, galvanised gas pipes will have to be replaced by the superior modern copper variety.

You may also face the prospect of converting from LPG (liquefied petroleum gas) to natural gas. A licensed gas plumber can handle all this for you.

Inside the property there may be major work to do, again with replacing old pipes, and also removing old appliances that have been there for decades. Obviously, this sort of work has to be approached carefully, and good quality up-to-date hardware installed.

Even if existing gas lines are safe, any kind of renovation or remodelling job will involve putting things in different places, and each step must be done properly and safely.

Similarly, even if the existing gas lines are of suitable quality and in good condition, the disruption of the renovation can cause problems which your new best friend, the gas fitting plumber, can sort out.

By the way, if you want an old-fashioned look to the kitchen, that can be arranged. There are modern versions of the homely old ranges on which, in films, there always seemed to be a pot of stew ready at all hours of the day and night.

If you inherited one of these when you bought the place, don’t get sentimental, get resourceful and find something that looks similarly attractive and soothing but does the job more effectively and a lot more safely.

Preparing for a plumbing emergency is probably the wrong way to put it. Being prepared is more to the point, and it is a process that starts even before a plumber sets foot in your building. If you are starting from scratch, having the premises built, you are perfectly placed to do the job properly. If you have bought or taken over something that has been in operation for some time, you may be kitting it out because your requirements are rather different or adapting what is there already. Either way, avoiding commercial property plumbing emergencies is the object of the exercise, and this starts with choosing a good company offering commercial plumbing services . That is to say, you probably don’t contact the people who installed your new shower cubicle at home and make their day with the prospect of a big job – unless you know they have the expertise and capacity to deal with that big job. This is no place for sentiment. You’re looking for an outfit that offers commercial emergency plumbing services as part of their regular commercial plumbing services. You will find them online and you’ll still see some advertising in the newspapers and local magazines. You may need to discuss your requirements with them and get an estimate, which will mean showing them around the premises and explaining a bit about what your business entails. Having a good working relationship with your tradies is very helpful and, in this case, can be critical. Nobody is anticipating commercial property plumbing emergencies , but these things happen and the better prepared you are, the greater the chance of minimising trouble. If there are flammable substances on your premises, for instance, the risk of fire increases dramatically, so you fire prevention strategy has to be extremely well thought out, and plumbing contingency planning is best done collaboratively. You know your business and the common hazards as well as the occasional ones that can occur without warning. Is a Fire a Plumbing Emergency? Having a good water supply in the building is clearly essential for all kinds of reasons, and fighting fires is one of them. However, the company carrying out your commercial plumbing services should be well aware of the limitations of water in that respect. Your fire emergency provisions may need to involve foam, dry powder, CO2 or even wet chemicals. However, water can still be essential for many types of blazes, and that is why the fire trucks are still geared up for dousing flames with good old H2O. Water-based Plumbing Emergencies The more common situations that could call for commercial emergency plumbing are leaks and bursts. A leak is a subtle, subversive threat that can suddenly spell trouble if water gets into machinery or the electrical system. Therefore, you need to have a plan for if this happens. Bursts are more dramatic and can cause flooding with clean water or wastewater, and whichever one it is, it needs to be shut down ASAP. Commercial Emergency Plumbing: What to do Let’s say you have taken care with your commercial plumbing services, but something happens anyway; what are you going to do? The most important thing is to stay calm, because racing around in a panic is not going to help. You need to make cool, rational decisions and the first one is to stop the emergency at its source. That might mean shutting down the water supply to a machine or shutting off the water altogether at the mains. It could mean throwing the master switch in the electricity box to avert any danger of electrocution. Call the emergency services immediately and once you have done what you can to stop the flow, get out of the building. You’ve seen the signs in hotels, and you’ve heard the safety briefings on planes: leave anything you don’t absolutely need and get out of there. An emergency is an emergency, and the crucial thing is to make sure everyone involved is safe, including yourself. The aftermath and the repercussions you can deal with afterwards. Preventing Commercial Property Plumbing Emergencies With luck you will never have to deal with a commercial property plumbing emergency, but you know what they say about luck: you make your own. Find a good provider of commercial plumbing services, work with them to get the best possible system in place and don’t let the whole thing down by cutting costs. Using good quality equipment installed and serviced by experts is the best kind of insurance. And there’s the other crucial word: maintenance. Get it done regularly and keep an eye out yourself. Nipping trouble in the bud can save a lot of heartache as well as money, so be vigilant and encourage your employees to do the same. At Mainline Plumbing & Civil, we can help you prevent commercial plumbing issues. Read more about our services here .

While plumbing in the home is a relatively straightforward business, with the kitchen and bathroom to look after plus the water tank and boiler, in commercial premises it can be a lot more complex, not least because of the scale. In a big commercial unit, you may have hundreds of metres of pipes plus various areas with different purposes and therefore different plumbing needs. It stands to reason, then, that the tradespeople who provide a good, cheerful service in residential settings are not necessarily the best choice for bigger buildings. There are extra considerations in a commercial building, with fire safety prominent among them, and this involves specialised training. There may also be working at height to consider, which again means gaining knowledge and expertise over and above the basic requirements of the plumber’s trade. Certification is needed in specialised areas and there are plumbing compliance standards to be met. Employees of an industrial plumbing contractor will have spent plenty of time studying to gain a thorough understanding of working in commercial settings – and there is a huge variety within the category. Take, for instance, the difference between a factory and an office block, a school’s classrooms and its gymnasium, and that’s before we get to the very special environments of clinical units like hospitals. Every commercial unit has a requirement for water, and a large-scale plumbing infrastructure presents very different issues from a two-bedroom home. Business Plumbing Solutions If you are having a building fitted out for a business, it is important to get a commercial plumbing contractor involved at an early stage. Plumbing has to be incorporated into the premises, rather than added on afterwards. If it’s an office suite, you may be thinking about the ambience, the light, the acoustics, and generally making sure it’s a good place for productivity – and productivity comes from people being comfortable and able to concentrate. While the kitchen area may not be high on your list of priorities, having a decent one is all part of being the kind of employer people want to work for. If you’re setting up an industrial unit there may be a requirement for some showers in addition to the usual washing and toilet facilities, but how big and where? An experienced industrial plumbing contractor can draw on past projects to show you what works and what doesn’t, thereby saving you from making errors that detract from the perceived status of the place of work. Everyone has relatively high standards these days, and it is important that the plumbing doesn’t let you down in either its scope or efficiency. You won’t find industrial options in the hardware superstore on your local industrial estate, so you can either make it up as you go along and take your chances or you can talk to someone accustomed to large-scale plumbing infrastructure. They’re not going to try to push you towards things you don’t need, because their job is to install and service units, not sell them. Having said that, they will have seen which options previous clients were happy with and those that people regretted and soon had to replace. What Extra Skills Do Licensed Commercial Plumbers Have? All plumbers are used to working in confined spaces, but in a big setting, particularly one with high ceilings, safety becomes even more important. A licensed commercial plumber will be trained to work in these conditions, and not only will they be more aware of safety, but because they are comfortable working like this, they can get a good job done rather than failing to do their best because they want to get it over with. Working at heights, for instance, is not something that just anyone would be prepared to do, but a company offering business plumbing solutions will have staff who can work safely up in the rafters while seeing to anything from water pipes to sprinklers. They will have a good knowledge of fire prevention and be able to provide the premises with fire hydrants and reels, the sort of hosing that rolls up flat for convenience and space-saving but turns into a big, fat hose full of water when needed. A plumbing company billing itself as commercial plumbing contractors should also be able to guide you through the legal requirements and point you towards the people to talk to at the council to make sure premises are up to scratch as regards local regulations. If You’re Taking Over an Existing Building Expert assistance is essential when you take over a property that someone else set up, because it is now your responsibility, and a good firm of commercial plumbing contractors will cast an expert eye over the setup to see if it’s okay as it is or needs upgrading. Health and safety regulations are not just obstacles put in your way by bureaucrats; they exist to safeguard your workforce and your customers. At Mainline Plumbing & Civil, we cover all commercial plumbing needs. Read more about those services here .
