Corroded pipes are a common issue in older homes and commercial properties across Australia. Over time, metal pipes—especially copper and galvanized steel—can deteriorate due to water quality, temperature, pressure, and exposure to other materials. At Same Day Trades, we provide expert solutions for corroded water pipes, whether it’s a leaking copper pipe, a rusted sink drainpipe, or damage to your hot water heater connections.

Our team is available 24/7 to inspect, repair, or replace corroded plumbing using long-lasting, corrosion-resistant materials. Same-day service is available for urgent issues.

Common Signs of Corroded Pipes

Corrosion may not always be visible, but there are clear warning signs that your pipes are breaking down:

  • Discolored or rusty water from taps
  • Metallic or unpleasant taste in water
  • Drops in water pressure
  • Water stains on ceilings or walls
  • Leaks near joints, water heaters, or under sinks
  • Moisture or mold growth in hidden areas
  • Warm areas on the floor (possible hot water pipe corrosion)

Ignoring these signs can lead to serious plumbing failures, damage to floors or walls, and higher water bills. Contact us for an inspection if any of these issues sound familiar.


Types of Corroded Pipes We Repair

Corroded Copper Water Pipes

Copper pipes are widely used for residential plumbing due to their durability. However, internal corrosion from low pH or hard water can cause pinhole leaks and discoloration. We carry out copper pipe corrosion repairs, replace damaged sections, and check surrounding lines for signs of wear.

Corroded Water Heater Pipes

Hot water systems are especially vulnerable to corrosion. Water heater inlet and outlet pipe corrosion can disrupt flow or cause leaks. Corrosion on water heater fittings is also a common source of gradual damage. Our team identifies and repairs corroded pipes on hot water heaters to prevent further issues.

Corroded Drain Pipe Under Sink

Under-sink plumbing is often exposed to moisture, leading to corroded drain pipes in bathrooms and kitchens. Signs include leaks, musty odors, or rust around connections. We replace corroded pipes under sinks and reseal connections to ensure lasting performance.

Corroded Pipes Under House or Behind Walls

Hidden pipes beneath flooring or inside walls may corrode silently. Common signs include rising damp, mold spots, and spikes in water usage. We detect and repair corroded pipes under houses using advanced tools to minimize disruption.

Water Heater Fitting Corrosion

Corrosion on water heater pipes and fittings often begins at joints or threaded connections. Corroded fittings may affect water quality and flow. Our licensed plumbers can replace affected parts and test the water heater to ensure full functionality.


What Causes Pipe Corrosion?

Corrosion happens when metal pipes react with elements in the water or surrounding environment. The most common causes include:

  • Hard water: Minerals in hard water accelerate hard water pipe corrosion.
  • Water chemistry: High or low pH levels can corrode copper and steel pipes.
  • Temperature fluctuations: Hot water heater pipe corrosion is common due to heat.
  • Mixed metals: Contact between copper and steel pipes may cause galvanic corrosion.
  • Old materials: Lead pipe corrosion and rusted galvanized steel are common in older homes.
  • High water pressure: Excess pressure stresses older or thinner pipes.
  • Standing water: Poor drainage may cause corrosion on water heater connections or under sinks.

We identify the root cause before making repairs to reduce the risk of future corrosion.


Risks of Leaving Corroded Plumbing Unrepaired

Corroded plumbing pipes can fail at any time. Even small leaks can cause larger problems if ignored. Risks include:

  • Burst pipes and sudden flooding
  • Damage to walls, ceilings, floors, or insulation
  • Mold and mildew from persistent dampness
  • Health concerns from lead or rust exposure
  • Reduced water flow and pressure
  • Total failure of water heaters due to pipe corrosion

Addressing corrosion early is more cost-effective than dealing with emergency repairs later.


Our Corroded Pipe Repair Process

Same Day Trades follows a precise, effective process to locate and resolve pipe corrosion:

1. Inspection and Diagnosis

We begin with a full inspection of affected areas. Our licensed plumbers use moisture meters, thermal imaging, and pressure testing to pinpoint issues like corroded copper water pipes, rusted drain lines, or leaking fittings.

2. Pipe Repair or Replacement

Once the corrosion is located, we determine whether a repair or full pipe replacement is needed. For small areas, copper pipe corrosion repair is often sufficient. For widespread corrosion, we recommend replacement using corrosion-resistant pipes.

3. Fixture and System Review

We check adjacent plumbing and systems to identify related corrosion problems. This includes corrosion on water heater pipes, fittings, and valves. Preventing further damage is part of every repair.

4. Testing and Cleanup

After completing the work, we test the water system for leaks and flow. Our team cleans up the work area and disposes of any damaged pipe materials.


Materials and Techniques Used

To prevent further corrosion, we use only high-quality, Australian-standard materials:

  • PEX and copper piping designed for corrosion resistance
  • Proper connectors to prevent galvanic corrosion between metals
  • Protective pipe sleeves and anti-corrosion wraps
  • High-pressure fittings for water heaters and supply lines
  • Sealants approved for drinking water systems

Our materials and installation methods are designed to last—and we back our work with a lifetime workmanship guarantee.


When Should Corroded Pipes Be Replaced?

While some small areas of corrosion can be patched or repaired, replacement is often the better long-term solution in these cases:

  • Multiple leaks in a short time
  • Corroded pipes under the house showing widespread decay
  • Lead pipe corrosion or outdated materials
  • Low water pressure across multiple taps
  • Corroded water supply lines near water heaters or meters
  • Water heater pipes corroding both at the inlet and outlet

Our plumbers explain all options clearly, with upfront pricing and no hidden charges.

Frequently Asked Questions

How do you fix a corroded water pipe?

Our plumber usually begins by checking where the corrosion has formed and how far it has spread. If only a small section is affected, that part can be removed and replaced. For larger damage or older piping systems, full pipe replacement may be the better long-term fix.

Do corroded pipes need to be replaced?

It depends on the condition of the pipe. If the corrosion is minor and isolated, a repair might be enough. But if the pipe is leaking from multiple areas or made from older materials like galvanized steel or lead, replacement is often the safer option.

Is it safe to drink water from corroded pipes?

Drinking water from corroded pipes isn’t recommended. Rust or metal particles can affect water quality and taste. In some cases, harmful materials like lead may be present in older pipes. It’s best to stop using the water for drinking until a professional has assessed the system.

How much does it cost to replace pipe corrosion?

The cost can vary based on where the pipe is located, how much needs replacing, and the material involved. Replacing a short section under a sink costs less than removing damaged pipes inside walls or under concrete. A licensed plumber can inspect the problem and provide an exact quote before work begins.

Living alone meant when my toilet and drain was not working I was completely stressed and had no idea what to do. From the initial phone call, to the first visit and quote for the job I was reassured and helped by each person...

Derek

Luke at Same Day Trades did a great job and was very professional and courteous as are all other tradespeople that I have dealt with from your company on the times that I have used your services.

We had a kitchen drain that was blocking up from grease. The plumber cleaned it out with Hydro jet drain cleaning machine. Drain is now back to original condition. Very happy with the works done.

Nikki B.

Preformed a great service and was very clear on pricing and what needed to be done before starting. Also went above and beyond to make sure there was no other problems elsewhere that needed attending too. Highly recommend!
