Common hot water system faults we repair today
Faults range from pilot outages to corroded tanks and blocked valves. We focus on fast diagnosis and safe, affordable repair so you get reliable service without delay.
No hot water or inconsistent temperature
Fluctuating output often points to failing thermostats, thermocouples or control parts. An extinguished pilot or ignition fault on a gas model can cause no heat.
Leaks, bursts and discoloured supply
Pooling near a tank or rusty taps usually indicates internal corrosion or an exhausted anode. We replace seals and worn parts to stop leaks quickly.
Low pressure, hissing or banging noises
Blocked strainers, failing valves or scale build‑up restrict flow and create banging or hissing. These signs mean the unit needs cleaning or valve replacement.
Pilot light, thermostat and safety valve faults
We test ignition systems and safety devices, including PTR valves. If repairs are uneconomic due to age or corrosion, we explain replacement options clearly.
For same‑day diagnosis and dependable service, call us on 1800 571 216 and we’ll prioritise a safe, effective fix.

Hot water system types we service and install
We install and maintain gas, electric, heat pump and solar systems with branded parts and full commissioning.
Below we outline the main options so you can see which type best suits your home or business.
Gas storage and continuous flow heaters
Gas storage units use insulated storage tanks and pilot-lit burners for fast recovery. They suit larger families and sites with high peak demand.
Continuous flow gas units heat on demand. Typical capacities range from 12–32 L/min; 26 L/min at a 25°C rise suits many homes.
Electric storage and instantaneous units
Electric storage tanks work well on off‑peak tariffs or continuous supply depending on usage patterns. Tariff choice affects running costs.
Electric instantaneous units provide on-demand supply but can be limited by household electrical capacity. Upgrades may be needed for higher flow rates.
Energy-efficient heat pump systems
Heat pump systems extract ambient heat to cut electricity use. They deliver reliable heated supply while reducing running costs compared with direct electric units.
Solar with electric or gas boosting
Solar options include roof-mounted (Hiline) or ground-level (Loline) tanks paired with electric or gas boosters. Location affects access, weight and servicing needs.
We provide full installation and changeover services, safe decommissioning of old equipment and commissioning tests. Call 1800 571 216 for advice or bookings.
| Type | Key benefit | Typical capacity | Best for |
|---|---|---|---|
| Gas storage | Fast recovery, reliable on high demand | 150–300 L storage tank | Large families, continuous use |
| Gas continuous flow | On‑demand efficiency | 12–32 L/min (common 26 L/min) | Average households wanting endless supply |
| Electric storage | Simple installation, off‑peak savings | 80–250 L storage tank | Smaller homes, off‑peak tariff users |
| Heat pump | Low running costs, efficient | Equivalent to 150–300 L storage output | Energy‑saving focus, moderate demand |
Costs, efficiency and choosing the right unit for your home
A clear plan that compares installation cost and expected energy use helps avoid surprises down the track. We provide transparent advice that balances upfront outlay with long‑term savings, focusing on affordable quality.
We compare real‑world running costs against installation expenses so you can see value over a unit’s service life. Continuous flow gas is usually efficient but can need extra retrofit work and flue changes when replacing storage models.
Balancing installation, running costs and retrofit work
Electric storage on off‑peak tariffs can cut ongoing bills compared with continuous tariffs. Solar and heat pump options raise installation cost but lower long‑term energy use.
We outline likely expenses and savings, including any retrofit gas or venting work so you can budget accurately before proceeding.
Right‑sizing capacity and placement to reduce dead legs
We assess household demand, peak times and flow expectations to recommend a correctly sized unit. Undersizing causes poor performance; oversizing wastes capital and energy.
- Compare installation costs with expected running costs over service life.
- Account for retrofit needs when switching from storage to continuous flow gas.
- Consider off‑peak electric schedules, or solar/heat pump tradeoffs for lower energy bills.
- Place the unit to reduce pipe runs and dead legs near kitchens and bathrooms.
We present a clear, upfront quote that factors servicing access, venting and compliance. Call us on 1800 571 216 for tailored guidance and a costed proposal that matches your needs.
Maintenance that prevents breakdowns and extends system life
Preventive checks reduce breakdowns and lengthen the life of your heating equipment. We recommend scheduled maintenance to keep systems safe and efficient across homes and businesses in Melbourne.
Five‑year service intervals for maximum safety and efficiency
We advise a full service about every five years. This helps maintain safe pressures and correct temperatures and protects your tank and storage components.
Pressure and temperature checks, PTR valve inspection
Our plumbers measure temperature and pressure, and inspect the PTR valve. We replace the valve per manufacturer guidance if needed to ensure safe relief.
Anode, thermocouple and gas controller assessment
We check the sacrificial anode and replace it to prevent corrosion. We test ignition components such as the thermocouple and gas controller on heaters for reliable lighting.
Cleaning burners, removing sludge and adjusting gas pressure
We clean pilots and burners, remove sludge from cylinders and adjust gas pressure to manufacturer settings. After the visit we provide a written report with recommendations for future installation or safety improvements.

FAQ
What common faults do we see with hot water systems and how quickly can they be fixed?
We often attend faults such as no heat or fluctuating temperature, leaks, discoloured supply, low pressure and noisy operation. Our technicians triage calls, isolate systems for safety and carry common parts to enable same‑day fixes where possible. For complex issues like tank replacement or major corrosion, we provide a clear timeline and upfront cost estimate.
Do we offer emergency response any time of day or night?
Yes — we provide 24/7 emergency service with rapid dispatch across greater metropolitan areas. Our phone triage helps us assess safety risks and prioritise urgent jobs, letting us send a licensed plumber with the right tools and replacement components quickly.
Are your plumbers licensed and which brands do you use for parts and replacements?
All our plumbers hold current Victorian plumbing licences and gas registration. We install and repair reputable brands such as Rinnai, Bosch, Rheem and Stiebel Eltron, and use manufacturer‑approved parts to maintain warranties and long‑term reliability.
What causes no heat or inconsistent temperature in a system?
Common causes include failed thermostats or thermocouples, blocked burners, scaling in elements or heat exchangers, and issues with gas control valves or electrical supply. We diagnose the root cause on site and recommend repair or replacement based on safety, efficiency and cost.
How do we handle leaks, bursts and discoloured supply?
Leaks may stem from failed fittings, corroded tanks or damaged valves. Discolouration often indicates corrosion or sediment build‑up. We isolate the unit, replace faulty valves, repair or replace sections of pipework and advise on tank replacement when corrosion is extensive.
What can cause low pressure, hissing or banging noises and can they be fixed quickly?
Low pressure can come from blocked inlet filters, scale build‑up or failing pressure regulators. Hissing or banging may indicate trapped air, water hammer or sediment hitting heating surfaces. We clear obstructions, fit water hammer arrestors if needed and descale components to restore normal operation.
How do you troubleshoot pilot light, thermostat and valve faults on gas units?
We check the pilot assembly, thermocouple and gas control valve for proper operation, confirm gas pressure and inspect the burner. If safety components fail, we replace them with certified parts and test ignition cycles and safety shutdowns before leaving site.
Which unit types do we service and install?
We service gas storage tanks, continuous flow (instantaneous) units, electric storage heaters, heat pump systems and solar units with electric or gas boosting. We tailor service and installation to the building type, household demand and energy goals.
What factors determine installation and running costs?
Installation costs depend on unit type, flue or venting requirements, location and any needed pipework or reticulation changes. Running costs vary by fuel type, unit efficiency and household usage. We provide estimates that compare upfront price, expected energy use and payback periods.
How do we size a system correctly to avoid wasted energy and dead legs?
We assess household demand, peak draw times, number of bathrooms and existing pipe layout. Right‑sizing limits storage losses and reduces long runs that create dead legs. For some homes, continuous flow or a heat pump offers better efficiency and lower standing losses.
What routine maintenance do we recommend to prevent breakdowns?
We recommend servicing every five years for many systems, with more frequent checks for high‑use or corrosive environments. Maintenance includes pressure and temperature checks, PTR valve inspection, anode rod assessment, cleaning burners, flushing tanks and adjusting controls to maintain efficiency.
How do we inspect and replace anode rods, thermocouples and gas controllers?
During service we remove and inspect the sacrificial anode for corrosion; if it’s depleted we replace it to extend tank life. We test thermocouples and gas controllers for reliable operation and replace any parts that fail safety or performance checks using OEM or approved components.
Do you work with solar and heat pump systems and handle boosting and controls?
Yes — we service solar collectors, tanks and electric or gas booster systems, and we install heat pump units with correct electrical supply and refrigerant handling. We also commission control systems and ensure integration with existing boosting arrangements for consistent supply.
