Hot Water System Repair, Replacement & Installation
Whether your existing system needs a small repair or it is finally time to upgrade, we repair, replace and install every kind of water heater, with same day service across Sydney.
Failed elements, faulty thermostats, worn valves, leaking fittings and pilot lights that will not stay lit - all diagnosed and repaired fast, with the common parts carried on the van. Most hot water repairs are completed in a single visit.
An old hot water unit that is leaking, rusted out or past its prime? We supply and install a like-for-like or upgraded system, often the same day, and we remove and dispose of the old unit for you at no extra cost.
Building, renovating or switching system types? We handle the full hot water system installation, including the gas or electrical connection, the relief valve and drain line, and the compliance certificate at the end.
Regular hot water maintenance - flushing the tank, checking the anode, testing the relief valve, servicing the burner - is the most effective way to extend the life of a water heater and keep energy costs down. Most people skip it until something breaks.
A burst tank, a major leak or a gas smell around the unit is a hot water emergency. We are available 24/7 for these, and we will talk you through isolating the unit safely while we are on the way.
Your Local Hot Water Plumber in Sydney
When the hot water goes, it is rarely convenient. It is a Saturday morning, or the middle of winter, or the day you have people staying. What you want is a hot water plumber who can tell you quickly whether the unit can be repaired or needs replacing, give you a straight price, and get it done.
R&G Plumbing, Gas & Drainage is a Gordon-based team with close to two decades of experience across Sydney. We are licensed plumbers and licensed gas fitters, which matters more than people realise: a gas hot water system legally requires a gas licence to work on, and you receive a compliance certificate on every gas install we complete.
We work on every type of water heater found in Sydney homes - gas storage and continuous flow, electric storage, heat pump and solar - and we service all the leading brands, including Rinnai, Rheem, Bosch, Dux, Aquamax, Stiebel Eltron and Sanden. Whether it is a failed element, a faulty thermostat, a leaking tank or a full hot water system replacement, we diagnose the real fault first and quote before we touch anything.
Call 0461 330 531 for same-day service, or request a free assessment, and we will come back to you quickly.
Signs Your Hot Water System Needs Repair or Replacement
A water heater rarely fails without warning. It usually gives you weeks of small hints first, and catching them early is the difference between a modest repair and an emergency replacement on a Sunday. Here is what to watch for.
A blocked drain can escalate quickly. A CCTV drain inspection will show the cause and the best fix.

Honest Advice, No Upselling
If your system can be repaired, we will repair it rather than replace it. We would rather do a small job well and be the people you call next time than sell you a water heater you did not need.
Electric, Heat Pump and Solar Hot Water
Electric Hot Water Systems
Electric water heaters are simple and reliable and found in a great many Sydney homes, often running on off-peak or tariff 33. Most faults come down to the element or the thermostat, and both are straightforward repairs. We also handle full replacements, including upgrading an ageing electric hot water heater to a more efficient system. Electric hot water systems remain the most common setup we service where it makes sense.
Heat Pump Hot Water
A heat pump does not generate heat directly - it moves it, drawing warmth from the surrounding air to heat the water, much like a reverse-cycle air conditioner. That makes it the most energy-efficient option available, often cutting hot water running costs substantially, and many models qualify for government rebates. We help you size one correctly for your household.
Solar Hot Water Systems
A solar water heater uses roof-mounted collectors and an electric or gas booster for cloudy days. We repair boosters, service panels and tanks, and replace ageing solar systems that have had their day. Solar is environmentally friendly and very economical to run, but it does need occasional servicing to stay that way.
Should You Repair or Replace Your Hot Water System?
This is the question we get asked on nearly every job, and the honest answer is that it depends on three things: the age of the unit, what has actually failed, and what the repair costs relative to a replacement.
As a rough guide, if the unit is under 8 years old and the fault is a component - an element, a thermostat, a valve, a thermocouple - repair it. These parts are designed to be replaced, and a repair will typically give you years more service for a fraction of the cost of a new system.
If the tank itself is leaking, or the unit is past about 10 to 12 years and has started needing repeated attention, replacement is almost always the better value. A corroded cylinder cannot be repaired, and pouring money into an old water heater one part at a time usually costs more in the end than replacing it once.
Replacement is also worth considering if your energy costs have crept up, or if your household has grown and the system can no longer keep up. Moving from an old electric storage tank to a heat pump, for instance, often pays for itself over time through lower running costs and available rebates. We will lay out both options with real numbers and let you make the call - we do not work on commission and we have no interest in selling you a system you do not need.
Gas Hot Water Repairs & Installation in Sydney
A gas hot water system is still the most common water heating choice across Sydney, and it is where most of our hot water work sits. Our licensed gas fitters repair, service and install both gas storage tanks and continuous flow units, and every gas job finishes with a compliance certificate.
A gas storage system heats and holds water in an insulated tank, ready for use. They are reliable and economical to run, but the tank has a finite life - usually around a decade - and once the cylinder corrodes it cannot be repaired, only replaced. Common faults we repair are the thermocouple, the gas control valve and the burner assembly.
A continuous flow unit heats water on demand as it passes through a heat exchanger, so it never runs out and it wastes nothing keeping a tank warm. They are more efficient and take up far less space. When they fail it is usually the ignition, the flame sensor, the water valve or a scaled-up heat exchanger - all of which we can repair.
Common Gas Hot Water Faults
- Pilot light will not stay lit - usually the thermocouple
- No ignition or a clicking sound with no flame
- Water heats then goes cold mid-shower - often the flame sensor or a scaled heat exchanger
- Fluctuating temperature and poor temperature control
- A smell of gas around the unit - treat this as urgent
If you can smell gas anywhere near the water heater, turn the gas off at the meter, ventilate the area and call us immediately on 0461 330 531. Gas leaks are not something to wait on, and only a licensed gas fitter should be working on the system.

Real Reviews from Satisfied Clients
I really appreciated the honest advice, attention to detail, and fair pricing. I highly recommend R&G Plumbing to anyone looking for reliable, fairly priced, and professional plumbing services.
Thank you again to the entire R&G Plumbing team!
Initially, it looked like the floor would need to be dug up for a 1.5 day job$$, which we couldn’t afford. Instead, Jack kept investigating and found another access point through our neighbour’s carpark ceiling. He organised access to neighbours garage, removed the roots, and repaired the pipe at a much more affordable price. The roots were way worse than we expected.
As a young couple and first home buyers, this was our first time dealing with a plumber and we were pretty stressed since we thought it was a simple blockage but it turned out to be a complex issue. I gotta check the drainage when im purchase property in the future. Learnt my lesson!
Jeremy and Zac explained everything clearly and provided a detailed report and invoice so we can raise it with strata, as the drainage is linked to other units and may have further issues.
Really grateful for the honesty and effort. We’ve definitely found a plumber we trust and would happily connect with Jeremy’s team again.

Hot Water Plumber Sydney FAQs
How quickly can you repair or replace my hot water system?
In most cases, the same day. We offer same day service for hot water repairs and replacements across Sydney, and we are available 24/7 for urgent situations such as a burst tank or a gas leak.
Should I repair my hot water system or replace it?
It depends on the age of the unit, what has failed and what the repair costs. If your water heater is under about 8 years old and a component has failed, repair is usually the sensible call. If the tank is leaking, or the unit is past 10 to 12 years and needing repeated repairs, replacement is generally better value. We explain both options plainly and let you decide.
How long does a hot water system last?
Most storage systems last around 8 to 12 years, and continuous flow units often longer. Regular hot water maintenance - checking the anode, flushing sediment, testing the relief valve - makes a real difference to how long you get.
How much do hot water system repairs cost in Sydney?
It depends entirely on the fault. Replacing a thermostat or an element is a modest job; a failed heat exchanger or a corroded cylinder is a different conversation. That is why we assess the system first and give you a fixed price before any work starts, with no call-out fee.
What type of hot water system is best for my home?
Gas continuous flow suits most homes with a gas connection and never runs out. Heat pumps are the most energy-efficient option and often qualify for rebates. Electric storage is simple and reliable. Solar has the lowest running costs but the highest upfront outlay. The right answer depends on your household size, your energy connection and how you actually use hot water. We will recommend based on that, not on what we happen to have on the van.
Do you repair gas hot water systems?
Yes - gas is the bulk of what we do. Our licensed gas fitters repair gas storage and continuous flow units, including thermocouples, gas control valves, burners, ignition faults and scaling. Every gas job comes with a compliance certificate.
Can you switch me from electric to gas, or to a heat pump?
Yes. Changing system type is common, usually to cut energy costs. We will talk you through what the changeover involves, what it will cost, and whether any rebates apply before you commit.
Do you carry parts and systems with you?
For most common jobs, yes. We carry elements, thermostats, valves and seals on the van, and we have direct access to every leading brand, so a new water heater can usually be on site the same day.
Are you licensed for both plumbing and gas?
Yes. Every job is done by a fully licensed plumber, and by a licensed gas fitter when gas is involved. You receive a compliance certificate at the end of every gas installation.
What brands do you install and service?
All the leading brands, including Rinnai, Rheem, Bosch, Dux, Aquamax, Stiebel Eltron, Sanden and Reece. If you have a particular brand in mind, just let us know.
