Water pipe installation is a crucial part of any home or business plumbing system. Whether you’re building new pipes or replacing old ones, getting it right means fewer headaches down the track. At All Needs Plumbing, we specialise in pipe relining, a modern, trenchless method that saves you time, money, and mess. Let me walk you through what water pipe installation involves, explain why pipe relining is a game-changer, and share some pro tips from my years in the trade.
What Is Water Pipe Installation?
Water pipe installation means laying down the pipes that bring fresh water into your property. Traditionally, this involved digging trenches, pulling out old pipes, and replacing them with new ones. While effective, this method can be disruptive, expensive, and time-consuming. That’s why pipe relining has become a popular alternative.
Pipe relining repairs or installs new linings inside existing pipes without the need for digging. It creates a strong, seamless “pipe within a pipe” that lasts for decades. This method is perfect for fixing leaks, cracks, or blockages and can sometimes be used for new pipe installations where access is tricky.
Types of Pipes We Work With
We install and reline various pipe materials, each with its own strengths and ideal uses:
PVC (Polyvinyl Chloride)
This plastic pipe is lightweight, affordable, and resistant to corrosion. It’s commonly used for cold water supply lines and drainage. PVC pipes are easy to work with and ideal for underground installations because they don’t rust or degrade easily.
Copper
For many years, copper pipes have been an essential part of plumbing. They are known for their durability and reliability. They handle hot and cold water well and resist bacterial growth. Copper is an excellent choice if you want a long-lasting pipe, though it tends to be more expensive than plastic options.
PEX (Cross-linked Polyethylene)
Because PEX pipes are flexible, they are easier to install, especially in small spaces. They’re also resistant to freezing and bursting and can handle both hot and cold water. Due to their versatility and cost-effectiveness, PEX is becoming increasingly popular in Australian homes.
CPVC (Chlorinated Polyvinyl Chloride) and HDPE (High-Density Polyethylene)
These pipes are designed for specific uses, like hot water lines and underground installations. CPVC can withstand higher temperatures, while HDPE is both rigid and flexible, making it ideal for trenchless installations.
Choosing the right pipe depends on your property’s needs, local regulations, and budget. We’ll help you pick the best option to ensure your plumbing system performs well for years to come.
How Pipe Relining Works
Pipe relining is a clever, minimally invasive way to fix or install water pipes without digging trenches. Here’s the step-by-step process we follow at All Needs Plumbing:
1. Inspection
We start by inserting a small CCTV camera into your existing pipes. This lets us see the inside condition, identify cracks, blockages, or corrosion, and measure the diameter and length of the pipe. This step ensures we know exactly what we’re dealing with before any work begins.
2. Cleaning
Next, we clean the pipes thoroughly using high-pressure water jets or mechanical tools. This removes any debris, roots, grease, or mineral buildup that could prevent the new lining from adhering correctly. A clean pipe is essential for a successful relining.
3. Liner Preparation
We prepare a flexible liner that’s soaked in a special epoxy resin. This liner is custom-cut to fit the exact length and diameter of your pipe. The resin is what hardens to form the new pipe inside your old one.
4. Insertion
Using compressed air or water pressure, we carefully insert the resin-soaked liner into your existing pipe. The liner unfolds and presses against the pipe walls, filling cracks and sealing leaks.
5. Curing
We then cure the resin to harden it. Depending on the resin type, this can be done with hot water, steam, or UV light. The curing process solidifies the liner, creating a rigid, seamless pipe inside the old one.
6. Final Check
After curing, we run the CCTV camera through again to ensure the lining is smooth, properly cured, and free of defects. We also test the water flow to confirm everything works perfectly.
The whole process usually takes just one day, and you won’t have to worry about trenches or major disruptions. It’s a clean, efficient way to extend the life of your pipes or install new ones where digging isn’t practical.
Pro Tip: If you embed PVC pipes in concrete, use sleeves or conduits around the pipe to prevent cracking from occurring. This protects the pipe from the concrete’s curing heat, making future repairs or replacements easier. It’s a small extra step that can save you big headaches later.
Installation Process for New Pipes
If you need new water pipes installed from scratch, we handle the entire process with care and professionalism:
Site Assessment and Permits
We begin by inspecting your property to determine the soil type, pipe routes, and access points. We’ll also help you get any necessary permits from local councils to ensure your installation complies with regulations.
Trenching and Excavation
When trenchless methods aren’t an option, we carefully dig trenches to lay the pipes. We minimise disruption to your garden, driveway, or landscaping.
Pipe Laying and Connections
We lay the pipes in the trench precisely, ensuring they have the proper slope and alignment. We then use high-quality fittings to securely connect the pipes, preventing leaks and ensuring a smooth water flow.
Backfilling and Protection
After laying the pipes, we backfill the trench with suitable soil or sand to protect them from damage. If the pipes run under concrete or in areas prone to damage, we also install protective sleeves or insulation to protect them.
Pressure Testing and Flushing
Before finishing, we pressure test the system to check for leaks and flush the pipes to remove debris. This ensures that your new water line is clean, safe, and ready to use.
Pro Tip: Always bury water pipes below the frost line to prevent freezing. In most parts of Australia, that means at least 12 to 18 inches underground. If you live in a colder area, check the depth of the frost line and bury pipes deeper. This simple step prevents costly burst pipes in winter.
FAQs About Water Pipe Installation
How Long Does Water Pipe Installation Take?
Typically, installing or relining a residential water line takes about one day for lines up to 20-65 feet long. The exact time depends on factors such as soil type, pipe material, and site accessibility. Rocky soil or tight spaces may slow the process. We always try to get work done quickly and with as little trouble as possible.
How Long Do Water Lines Last?
Water lines can last for decades—up to 70 years or more—depending on the material and the quality of installation. Copper pipes last the longest. PVC and PEX pipes last a little less, but they are still durable. Older pipes can last a lot longer if you line them. This can save you a lot of money on replacements.
Can I Run My Water Line?
While some might consider DIY, installing a water pipe requires permits and must meet strict plumbing codes. Incorrect installation can cause leaks, contamination, or system failures. We strongly recommend hiring licensed professionals like us to ensure safety and compliance. We’ve seen many DIY jobs that ended up costing more in repairs and wasted time.
Can I Bury PVC Pipe in Concrete?
Yes, if installed correctly, PVC pipes can be buried in concrete slabs. Using sleeves and ensuring proper curing protects the pipe, allowing for future maintenance. We always follow best practices to ensure your pipes stay safe and accessible.
How Far Underground Does a Water Pipe Need to Be?
Water pipes should be buried below the frost line to prevent freezing. This is usually 12 to 18 inches in warmer areas but deeper in colder climates. Local regulations also specify minimum depths. We constantly check local codes and soil conditions before installation to ensure your pipes are safe and compliant.
