Plumbing a new home is a big part of the build that ensures comfort, efficiency and durability. A good plumbing system means smooth water supply, efficient drainage and minimal maintenance.
Here are 8 tips to help you plan and plumber your new home:
1. Start with a Full Plumbing Plan
A full plumbing plan is the base of a good system. It determines where the pipes, fixtures and appliances go, and is best planned early in the design stage to avoid costly changes later.
Work with your architect and builder to align the plumbing layout with the overall floor plan. Place wet areas like bathrooms, kitchens and laundries close together to minimise pipe runs and save costs.
Make sure there’s enough space for larger fixtures like bathtubs and washing machines. Don’t forget to plan for outdoor plumbing like garden taps or irrigation systems.
2. Hot Water System
Hot water systems are a part of any modern home and choosing the right one will ensure efficiency and comfort. There are many types to choose from including electric, gas, solar and heat pump water heaters.
Think about the size of your household and your energy usage when choosing a system. For larger families continuous flow (tankless) water heaters are a good choice as they provide endless hot water without the need for a big storage tank.
Solar water heaters are an eco-friendly option, reducing your reliance on electricity or gas. Position the system close to the bathrooms and kitchens to minimize heat loss in the pipes.
3. Use Good Quality Materials
The materials you use for pipes, fittings and fixtures will impact the life and reliability of your plumbing system. Cheap materials may save you money upfront but will often lead to leaks, corrosion or bursts down the track.
Use durable materials like copper or PEX (cross-linked polyethylene) for your pipes. Copper is strong and resistant to bacteria, PEX is flexible and easy to install.
For fixtures use stainless steel or brass as they resist corrosion and wear better than cheaper options.
Always use materials that meet industry standards for safety and performance.
4. Water Efficiency
A water efficient plumbing system not only saves you money on your bills but is also good for the environment. Modern fixtures and appliances are designed to save water without compromising performance.
Install dual-flush toilets, low-flow showerheads and taps with aerators to reduce water consumption. Consider a greywater system to recycle water from sinks and washing machines for toilets or irrigation.
Doing this from the start will save thousands of litres of water a year and your household costs.
5. Drainage Systems
A good drainage system is key to preventing water damage, blockages and bad smells. Drainage pipes should be sloped correctly to allow smooth flow of wastewater and adequate venting is essential to maintain air pressure and prevent suction that can disrupt water flow.
Plan for stormwater drainage to manage heavy rainfall especially in areas with changing weather. Use grated trench drains or channel drains in driveways and patios to prevent water pooling.
Make sure drainage pipes are accessible for maintenance as clogs can develop over time.
6. Ventilation
Ventilation is often the most overlooked part of plumbing. Proper ventilation ensures air flows freely through the pipes and prevents pressure imbalances and sewer gases entering your home.
Add vent pipes to your plumbing design especially for multi-storey homes where vertical plumbing stacks are common. These pipes allow air to escape safely and maintain the system’s performance.
Talk to your plumber to ensure compliance with building codes and optimal performance.
7. Outdoor Plumbing
Outdoor plumbing adds functionality to your property for gardening, car washing and outdoor cleaning. Properly installed outdoor systems can also increase your home’s value.
Plan for outdoor taps, irrigation systems and even outdoor showers if needed. Install frost-proof taps and insulated pipes to protect them from extreme temperatures.
If you’re installing a rainwater harvesting system make sure the tank is accessible and connected to outdoor taps or toilets.
8. Get a Professional Plumber
While it’s tempting to save costs by doing some of the plumbing yourself, hiring a licensed professional is essential. Plumbing is a complex system and mistakes can lead to costly repairs, poor performance or even safety hazards.
A professional plumber will ensure your system meets building codes and standards and will give you expert advice on material selection, layout and installation. They can also identify potential problems before they become major issues and save you money in the long run.
Always check the plumber’s credentials, experience and references to make sure you’re hiring the right person for the job.

Plan for the Future
When designing your plumbing system, think ahead. If you plan to add a second bathroom, laundry or outdoor kitchen in the future, include those in the initial design. This will save you time and money later.
Insulate
Insulate your pipes to improve energy efficiency and protect them from extreme temperatures. Insulated pipes will maintain water temperature, reduce energy consumption for heating and prevent freezing in cold climates.
Maintenance
Even a brand new plumbing system needs maintenance to stay in top condition. Schedule regular inspections to check for leaks, clogs or other issues. Fixing small problems before they become big ones.
