Emergency Steps
When you have a hot water system emergency in Sydney, follow these steps to ensure your situation is handled effectively before our reliable plumbers arrive:
Knowing the exact location of your hot water heater is crucial. It might be upstairs, downstairs, internal, or external.
If your hot water system is leaking, locate the control valve. For electric storage tanks, the valve is usually at the base of the tank. For continuous flow systems, it’s typically underneath the heater. If water continues to flow, locate and turn off the water meter.
If possible, turn off your power supply to prevent any electrical hazards. For electric hot water heaters, you might also need to turn off the circuit breaker to avoid the heating element turning on unexpectedly.
If you have a gas hot water system, turn off the gas supply until our specialist plumber arrives to assess and repair the issue.

Hot Water System Maintenance Near You
Do hot water systems need to be maintained? The answer is a resounding YES!
Hot water systems are often out of sight, leading to them being overlooked. Despite their hidden location, they work hard to provide hot water for showers, taps, washing machines, and dishwashers. Given their daily use, regular hot water system maintenance is crucial for efficiency and longevity.
When servicing a hot water system with a storage tank, there are 6 main aspects that will usually be assessed by our team.
- Checking for any visible signs of water heater leakage
- Replacing the sacrificial anodes that are stored in your hot water tank if needs be
- Check the pressure and temperature of the water tank
- Check the static flow and working flow of the water pressure
- Check the electrical element at the base of the system
The maintenance for a continuous flow hot water system is slightly different. Our plumber will usually perform the following checks at a service to ensure your unit is efficient and running to its best performance.
- Check the fan function.
- Inspect the heat exchange.
- Test the gas pressure.
- Assess the isolation valve is working properly.

We struggled to have any plumber who wanted to take on the job. Then Ryan came along. We were quoted on the spot and we were booked in straight away. Matt came by to do the job for us, he was so nice and informative. Professional and efficient and nice to boot. I can't remember the receptionist's name but she knew exactly what I was talking about. So helpful. Thankyou.
Phillip did a brilliant job, friendly, professional, and got the job done efficiently.highly recommended👍
Just had some Downlights upgraded with Network Reece could not be more helpful and professional
Ryan, Phil & Oliver were very professional, helpful & fixed my several problems.
Great work by Oliver Jake and Phil. Everything works perfectly
Matthew was swift to respond and diagnose the issue with our lack of water pressure. Initial estimates indicated the need to temporarily bypass a section of piping until we could locate the blockage before performing a more permanent solution. During testing for pipe location it was determined a faulty isolation valve was the culprit negating the need for the temporary solution and significantly reducing the cost of the solution. Matthew was courteous and professional throughout and once diagnosed correctly was a swift fix, would highly recommend.
Over two days of working outside to unblock a private stormwater easement affecting four properties on the same easement, Phil and Matthew brought us success. Happy to have them anytime. Great workers. Network you certainly have the right people for the job.
Network Plumbing is excellent! Another emergency blocked loo! So close to Christmas I didn’t think the issue would be resolved and I would have cancel planned celebrations . One phone call and Tim arrived within 3 hours resolving the problem. Tim is absolute gentleman! Every person I deal with at company is so professional. It says a lot about the owner, Scott who staff speak so highly of and respect . I cannot recommend this company more highly. Number 1 in my opinion!! Thank you for coming my rescue again Network plumbing. Kerrie-Ann
Phillip and Shaun. Very happy with the service
Phillip and Chase have done a marvellous job here today. Arrived on time, worked very efficiently and finished in very good time. Did a beautiful job!! Thanks chaps!! Hope we don’t need you again but would really welcome you if we do!!
I can’t speak highly enough of my experience with Network Plumbing. The plumber, Spencer, was polite, prompt and professional. He communicated my plumbing issues so I understood my options and then followed through with quotes and action. Excellent service! 👍

Frequently asked questions
Do you have more burning questions about leaking taps, a blocked toilet or your plumbing system? Here are some plumbing solutions.
Hot water repair costs vary depending on the system type, age, and the part that’s failed. Some issues are minor and quick to fix, while others involve critical components that need careful assessment.
Rather than guessing over the phone, our Sydney technicians inspect the system on site, explain what’s gone wrong, and walk you through the most sensible repair options before any work begins.
In many cases, yes – especially if the system is relatively young and the fault is isolated. Repairs can be a cost effective way to restore hot water quickly.
However, if the system is older or experiencing repeated failures, replacement may be the better long term option. A professional assessment helps you make the right call based on safety, reliability, and value, not guesswork.
Yes. Licensed plumbers, and gas fitters for gas systems – repair, service, and replace hot water systems. Because hot water systems involve water pressure, electricity, or gas, work must be done by a properly licensed professional.
Our Sydney team is trained across electric, gas, and heat pump systems.
Most hot water systems last 10–15 years, depending on the type, usage, water quality, and maintenance. Regular servicing can extend lifespan, while hard water and heavy usage can shorten it.
Knowing the age of your system helps determine whether repair or replacement makes the most sense.
It depends on the system’s age and the nature of the fault. Repairs on newer systems are often worthwhile, while major component failures on older units may make replacement the smarter long-term option.
Our approach is to assess the system properly and explain the pros and cons of each option before you decide.
Common issues include failed heating elements, faulty thermostats, gas ignition problems, sediment build-up, and pressure relief valve issues.
Many of these problems show early warning signs before total failure, which is why timely inspection can prevent complete loss of hot water.
Service costs vary depending on system type, access, and what checks or adjustments are required. Rather than applying flat assumptions, we inspect the system on site and explain what the service involves before proceeding.
There’s no set rule, but being without hot water for more than a day — especially during cooler months – is generally considered disruptive and should be addressed promptly.
If hot water loss affects hygiene, health, or daily living, it’s worth having the system assessed sooner rather than later.
Diagnosis involves checking power or gas supply, thermostats, heating elements or burners, pressure levels, safety valves, and overall system condition.
Because each system behaves differently, proper diagnosis requires onsite inspection rather than phone assumptions.
A quick first check is whether power or gas supply has been interrupted, such as a tripped circuit breaker or extinguished pilot light.
If supply is present and there’s still no hot water, it’s best to have a licensed technician assess the system to avoid safety risks or further damage.
The most common causes are failed heating elements (electric), ignition or gas supply issues (gas), thermostat faults, or system shutdowns due to safety mechanisms.
Each cause requires a different solution, which is why professional diagnosis is important.
Warning signs often include:
• Fluctuating water temperature
• Reduced hot water supply
• Strange noises from the tank
• Rusty or discoloured water
• Small leaks around valves or the base
Catching these signs early can prevent full system failure.
