Hot water system issues in St Leonards, such as inconsistent temperature, no hot water, or visible leaks from the tank or pipework, often indicate component failure, sediment buildup, or incorrect system sizing for household demand. Fixed Today Plumbing diagnoses hot water faults onsite, identifies the failed component or underlying cause, and provides a fixed-price quote for repair or replacement depending on the system's age and condition. This covers electric storage, gas continuous flow, gas storage, and heat pump systems from major brands including Rheem, Dux, Rinnai, Vulcan, Aquamax, and Thermann; where a system has reached end-of-life or repair costs approach replacement value, we explain the options and help you select a new unit that matches your household size, fuel type preference, and installation constraints.
Hot water systems fail for predictable reasons tied to age and usage patterns. Electric storage tanks develop sediment layers at the base, which insulate the heating element and reduce efficiency until the element burns out from overwork. The sacrificial anode rod inside the tank, designed to corrode preferentially and protect the steel lining, eventually depletes, allowing the tank itself to rust through. Gas continuous-flow units experience burner fouling, heat exchanger scale buildup, and ignition component failures, particularly in areas with hard water.
The first sign of trouble is usually temperature inconsistency: hot water that runs cold mid-shower, takes longer to heat, or arrives discoloured with rust particles. These symptoms suggest the system is struggling and likely close to failure. Visible leaks from the tank base or pressure relief valve discharge are more urgent, indicating internal corrosion or excessive pressure that needs immediate assessment.
When we assess a faulty hot water service, we check the power supply or gas supply first, then test the heating elements or burners, inspect the thermostat and temperature controls, examine the tank for corrosion or leaks, and measure the water temperature at the outlet. For systems that have stopped heating entirely, the fault is usually a failed element, thermostat, or gas valve. For systems producing intermittent or inadequate hot water, sediment buildup or undersized capacity is more likely.
Repairs make sense when the system is relatively young and the fault is isolated to a replaceable component such as an element, thermostat, or pressure valve. Replacement becomes the better option when the tank is corroded, multiple components have failed, or the unit is more than ten years old and showing general wear. At that point, investing in repairs often just delays the inevitable, and a new system offers better efficiency and a fresh warranty period.
For new installations, we guide you through the decision based on household size, existing fuel availability, and installation location. Electric storage is straightforward and suits smaller households or properties without gas connections. Gas continuous-flow systems provide endless hot water on demand and suit larger households with simultaneous usage needs, though they require adequate gas supply and proper venting. Heat pumps extract ambient heat from the air and are the most energy-efficient option long-term, though they have higher upfront costs and work less effectively in very cold climates.
All hot water installations include tempering valves to limit outlet temperature to 50°C at tapware (preventing scalding), pressure relief valves to prevent tank over-pressurisation, and compliance with AS/NZS 3500 plumbing standards. For gas systems, we also ensure correct flue installation and combustion ventilation. Once installed, the system is tested under operating conditions and confirmed to deliver stable hot water at the set temperature before leaving.
Fixed Today Plumbing provides a Lifetime Labour Warranty on all workmanship, meaning if a fault develops due to how the repair or installation was performed, we return and rectify it at no additional cost. Manufacturer warranties on the hardware itself vary by brand and model, and we explain those terms when quoting so you understand what's covered and for how long.
