Plumbing for new homes done right the first time

When you’re building, you only get one shot at getting the plumbing right. Once pipes are buried under a slab or walls are lined, mistakes turn into expensive headaches. Outright Plumbing plans, installs, and tests every system properly from the very beginning, so you can move in confident that everything will work the way it should.

  • We design and rough-in plumbing layouts before the slab is poured to avoid costly relocations later.
  • We install high-quality sewer, stormwater, and water supply lines with the correct falls, joints, and inspection points.
  • We fit off kitchens, bathrooms, and laundries with precision, making sure fixtures align neatly with cabinetry and tiling.
  • We supply and connect hot water systems, test pressures, and certify everything for compliance.

Every task is a cinch for Outright Plumbing

Every build has its quirks, but most projects fall into a few common scenarios. Here’s how we make sure the plumbing side runs smoothly.

Planning and designing the plumbing layout

Before a slab is poured, we map out water and waste lines to suit the design of the house. We look at fixture placement, fall of the land, and council requirements to make sure everything will work long-term — not just on paper.

Installing kitchens, bathrooms, and laundries

These are the busiest rooms in the house, and they rely on good plumbing more than anything else. We install water and waste connections for sinks, toilets, showers, dishwashers, and washing machines, making sure everything lines up perfectly with cabinetry and tiling.

Connecting sewers and stormwater to the mains

A house is only as good as its drains. We install sewer and stormwater lines with the correct fall, join them to boundary traps and council mains, and test every joint so there are no surprises once you move in.

Fitting hot water systems and ensuring compliance

From electric storage tanks to continuous-flow gas systems, we fit the right hot water unit for the house and make sure it’s compliant with energy and safety standards. We also run pressure tests to protect the whole system.

Six things you should know about plumbing in new builds

Plumbing is one of the most critical trades in a new build — but because it’s hidden, many people don’t think about it until something goes wrong. Here’s what separates a quality job from one that causes problems down the track.

Rough-in happens before concrete, not after

Once a slab is down, pipes can’t be shifted without saw-cutting concrete. That’s why licensed plumbers lock in water and waste pipe locations before the pour, coordinating with builders and drafts so fixtures line up perfectly later.

The fall of the land dictates drainage design

Stormwater and sewer lines rely on gravity. A block with poor natural fall needs carefully planned drainage grades or even pump systems. Get it wrong, and you’ll have slow-draining showers or stormwater backing up into the yard. We survey site levels and plan pipework to keep water moving properly.

Not all pipework is created equal

Builders sometimes push for cheaper pipe materials to save costs, but these split, deform, or clog faster. We use high-grade PVC and copper that meet Australian Standards, pressure-test every run, and ensure pipes are bedded properly so they don’t shift once the soil settles.

Inspection points make future maintenance possible

A new house without properly placed inspection openings is a nightmare to maintain. We install access points at key junctions, boundaries, and changes of direction so blockages can be cleared without ripping up landscaping or floors.

Water efficiency pays for itself

WELS-rated toilets, mixers, and showers aren’t just about ticking a box. With 4-star fixtures, a family of four can save tens of thousands of litres a year. We guide you toward systems that cut bills without sacrificing performance.

Compliance and certification aren’t optional

Plumbing in new builds must pass staged inspections under AS/NZS 3500. Skipping compliance or rushing inspections leads to failed approvals, costly rework, and delays to occupancy. We supply all required compliance certificates and liaise with inspectors so the job passes first time.

Common questions about new home build plumbing

Every project comes with its own challenges, and builders often have similar questions about plumbing for new homes and developments. Our FAQs share clear, practical answers so you know exactly what to expect.

What plumbing services are included in a full new home build package?

On a new home build you want one plumbing crew who can do the lot. Outright Plumbing takes that responsibility on every project we’re part of, so you don’t have to manage multiple trades or worry about gaps in the job. From the first trenches through to the final compliance checks, we handle the whole scope.

Our work covers all of the core areas you’d expect in commercial and industrial plumbing services, backed by the systems and experience to match the size of the build. That usually includes:

  • Complete plumbing installations for water, drainage and gas.
  • Safe and compliant gas fittings for hot water, cooking and heating.
  • Hot water systems fitted and ready for use.
  • Blocked drain prevention and clearing to keep everything flowing properly.

Every project has its own demands, and Outright Plumbing scales our work to suit. Whether you’re managing a multi-unit site or a one-off home, we make sure the plumbing is built to spec, tested properly, and ready for compliance.

Can you assist with plumbing design during the planning stage?

Yes, and Outright Plumbing often steps in at this stage to make life easier for builders and developers. Plumbing works best when it’s planned around the build from the start, not bolted on at the end. By involving us early, you avoid rework, cost blowouts and scheduling issues once construction begins.

As roof plumbing and drainage experts, we’re used to collaborating with builders, engineers and architects to get the design right. We act as plumbing specialists who can spot potential issues, suggest practical solutions, and make sure every detail aligns with both compliance standards and your build schedule.

Every site has its own conditions, and the complexity of the plumbing can vary a lot. By working with Outright Plumbing at the design stage, you’ll know the system is thought through, compliant, and ready to slot into place when construction gets underway.

Are you experienced in meeting OH&S and site safety requirements for large developments?

Yes, we are. On large builds, safety and compliance matter just as much as the plumbing itself. Outright Plumbing has worked on plenty of large-scale jobs where OH&S standards are front and centre, so we know what’s expected.

We come onto site with the right PPE, tickets and insurances, and we follow inductions closely. Just as important, we coordinate with site managers and other trades so our work doesn’t clash with theirs.

Every site has its own plumbing need, whether that’s dealing with deep trenches, heavy machinery, or tricky access. We plan ahead, stick to the rules, and keep your commercial projects running safely and on schedule.

How do you manage plumbing for heritage-listed or council-sensitive sites?

These jobs always need extra care, and we’ve built up the experience to manage them without slowing you down. Before we start, we confirm exactly what the council requires so there are no surprises once work is underway.

We also adapt how we work to suit the property. Heritage buildings often need special attention around Victorian Building Authority plumbing standards, and we make sure our approach meets those requirements while protecting the structure.

A lot of that comes down to roof and drainage work, which is often where heritage restrictions are strictest. Outright Plumbing takes the time to get those details right, so you can hand over a site that ticks all the boxes for both compliance and function.

Can you provide input on sustainable or water-saving plumbing solutions for new builds?

Yes, we can. Builders and developers are under more pressure than ever to deliver homes that are efficient and sustainable, and plumbing plays a big part in that. Outright Plumbing can advise on practical ways to cut water use and improve efficiency without adding unnecessary complexity to the build.

That might mean selecting fixtures with better water ratings, designing smarter drainage layouts, or installing energy-efficient hot water systems. We also look at long-term reliability, because there’s no point fitting a system that saves water now but fails in a few years.

By getting us involved early, you’ll know the plumbing design isn’t just compliant, but also meets the expectations of modern buyers who are looking for greener homes.

Do you provide aftercare or maintenance support once the build is complete?

We do. Our job doesn’t end the day the compliance certificate is signed off — we know new builds still need support once the owners move in. Outright Plumbing offers ongoing services to keep everything running the way it should, which is a big help for builders, developers and strata managers who want peace of mind after handover.

That includes regular servicing, warranty call-outs, and tailored packages for sites with more complex setups. Our plumbing maintenance team can also take care of complex plumbing maintenance services for multi-dwelling developments or commercial builds where the systems are larger and need specialist attention.

This way, you know the plumbing isn’t just done right during construction — it’s backed by a team who’ll be there to keep it performing long after the build is complete.

Can you provide same-day support if something goes wrong during construction?

Yes, we can. On a busy site, a plumbing issue can put the whole schedule at risk, so fast support matters. Outright Plumbing offers emergency services to get you back on track the same day.

If something bursts, blocks or fails during construction, we’ll prioritise your call and send a licensed plumber out straight away. Our team has the experience and equipment to deal with urgent problems safely, whether it’s a water supply issue, a blocked sewer, or a safety concern.

By having us on call, you don’t have to stress about downtime. We’ll step in quickly, resolve the issue, and let your crew keep moving with as little disruption as possible.

What happens if a defect is found after the final inspection?

Defects are rare, but they can happen. If something comes up after handover, Outright Plumbing will take responsibility and put it right. Our work is backed by compliance certificates and workmanship guarantees, so you’re never left carrying the problem alone.

For issues like leaks, fittings or even plumbing repairs, we’ll return to site, diagnose the cause, and fix it properly. If it’s covered by warranty, there’s no extra cost to you.

You can trust that when we finish a job, we stand by it. And if anything isn’t up to scratch, we’ll make it right without delay — that’s the standard we hold ourselves to on every build.
