Plumber Dolls Point

Our plumbers recently attended a property in Kurnell, on the south side of Botany Bay. 

The resident reported a burst pipe that had flooded their bathroom. Our team turned both the hot and cold water supply off so they could work onthe burst pipe safely and efficiently. The pipe was made out of old copper with soft-soldered joints and was approximately 30 to 40 years old. Unlike newer silver-soldered joints, copper joints are prone to cracking and failing suddenly, leading to frequent leaks.

Due to the copper pipework, our plumbers couldn't resolder it and call it a day. The affected parts of the pipe (both internal and external) had to be carefully cut out, removed and replaced with newer, copper press fittings. To ensure the new pipes were secure and leak-proof, our plumbers thoroughly pressure tested it.

After all the checks were completed, the plumbing system was turned back on and the client was happy.

Complex Water Leak and Pipe Replacement on Mandible Street, Alexandria

Our plumbers were called to a major water leak beneath Mandible Street in Alexandria. There was water all over the centre of the road and Sydney Water had advised us that it was likely coming from a fire service pipe. Since these pipes are used only for firefighting and rarely inspected, they tend to corrode over time, leading to underground failures and leaks with little to no warning.

As Mandile Street is a busy road and is a mix of residential and commercial areas, the local council required us to complete all work at night to manage safety and traffic flow.

What Our Plumbers Found

Once our plumbers shut down the water supply and exposed the leaking pipe using their non-destructive digging techniques, they discovered that the pipe was severely corroded. The corrosion was so severe that repairs would be impractical, so a full replacement was needed.

Our plumbers got to work, replacing 25 metres of steel pipe from the connection point on the opposite side of the road to the building. We also upsized the copper pipe to allow for a higher rate of water flow in the future as the area grows.

How the Work Was Completed

Works were carried out over multiple nights and included:

• Saw cutting and excavation
• Removing the damaged pipe
• Installing new copper pipework
• Installing hydrants and backflow devices
• Backfilling and restoring the roadway

Installing A New Isolation Valve Without Shutting Down Water to 100 Apartments in Mascot

Everyday Plumbing was recently called to a mixed commercial and residential building in Mascot to carry out some plumbing works. However, before the works could start, our team noticed a significant challenge - the water supply pipe connected to the commercial part of the building had no isolation valve installed. This pipe also supplied cold water to 11 storeys of the building as well as 100 apartments.

Without an isolation valve, if we were to start any plumbing job would need to shut off the entire building's water supply. For a large building like this, the disturbances would be substantial.

To avoid building-wide disruptions and water loss, our plumbing team used specialised pipe-freezing technology to complete the job quickly and effectively.

Why Are Isolation Valves So Important?

Isolation valves are an integral part of any commercial plumbing system. This valve allows sections of the pipe to be isolated for maintenance and repairs.

In this case, having no isolation valve installed meant that there was no safe way to work on the pipe without affecting hundreds of residents. The pipe in question also extended 20 metres up through the building, which created additional safety risks if the pipe needed to be cut.

Using Pipe Freezing Technology to Keep The Water Running

To maintain water throughout the building, our plumbers used a live pipe freezing method.

Pipe freezing creates a temporary ice plug inside the pipe, allowing plumbers to safely isolate a section of the pipework without draining the system or shutting off the water supply.

For this job, we froze the pipe on both sides so we could install an isolation valve.

Upstream Freeze

Freezing the upstream side prevented pressurised water from entering our work area so we could install the new isolation valve quickly and safely.

Downstream Freeze

The downstream side was also frozen. This was an important step as 20 metres of a 50mm pipe remained full of water. Without the downstream freeze, cutting the pipe would result in flooding.

Installing the New Isolation Valve

With both ends of the pipe successfully frozen, a new isolation valve was installed using crimp fittings. Crimp fittings are highly reliable, quick to install, and eliminate the need for hot works and cutting, providing a safer installation method within the confined plant room environment.

The Result

The new isolation valve was installed successfully without interrupting the building's water supply. This building now benefits from a dedicated isolation point, making it easier for future maintenance, repairs and upgrades to be done without disturbing the water supply.

The plumbing team at Everyday Plumbing were called out to a strata complex of villas in Kirrawee. This complex of villas had been experiencing multiple burst pipes and it was causing issues for the residents. Our testing revealed the pressure was over 1100kpa - AS3500 states a maximum pressure of 500kpa to domestic residence. The main water meter 32mm water frozen with liquid nitrogen, slightly relocated (to create additional room) modified with new isolation valve and and pressure reduction valve was installed. This resolved the complexes issues and brought the pressure within limits.

Our Assessment Of The Pipes

When dealing with repeated burst pipes, it's important to look beyond the initial damage and assess the condition of the entire system. Our plumbers carried out a detailed inspection of the affected areas and reviewed the history of recent pipe failures throughout the complex.

Recurring burst pipes can often be linked to factors like:

• Aging infrastructure 
• Corrosion
• Excessively high water pressure
• Environmental factors like ground movement
• Hidden leaks

Developing a Cost-Effective Solution

Rather than reacting to each burst pipe when they happen, our plumbers worked together to come up with a proactive plumbing strategy. Our recommendations focused on improving the reliability of the complex's water infrastructure while helping to minimise future maintenance costs and emergency call-outs.

Our plan considered:

• The age and condition of the villa's existing pipes and plumbing systems
• Long-term maintenance needs
• Minimising disruption to the residents
• Reducing future burst pipes
• Protecting the complex and the villas from water damage

Once we had assessed the plumbing, we installed a pressure-reducing valve. This valve is used to lower and stabilise incoming water pressure, protecting the complex's plumbing from dangerously high pressure.

The Result

By using our advanced tools to investigate the underlying causes of the repeated burst pipes, Everday Plumbing delivered a long-lasting and effective solution.
