We provide straightforward advice based on the condition, age, efficiency and repairability of the existing system.

- Faulty valves and fittings

Signs your hot water system needs attention
Some hot water faults develop gradually, while others cause an immediate loss of hot water or a significant water leak.
No hot water
A complete loss of hot water may be caused by a failed heating element, thermostat, gas supply issue, ignition fault, electrical problem or a system that has reached the end of its useful life.
Hot water runs out too quickly
The system may be undersized, inefficient, partially faulty or struggling to meet increased demand within the property.
Leaking tank or pipework
Water around the hot water unit may indicate a leaking valve, damaged fitting, corroded tank or excessive pressure within the system.
Unusual noises
Rumbling, popping or banging sounds can be associated with sediment build-up, pressure issues, ageing components or internal system deterioration.
Discoloured water
Rust-coloured or dirty hot water may indicate corrosion inside the tank, deterioration of internal components or ageing pipework.
Temperature changes
Water that becomes unexpectedly cold, excessively hot or inconsistent may require inspection of the thermostat, tempering valve, heating components or system controls.
Is your hot water system leaking?
A leaking hot water system should be inspected promptly, especially if water is spreading through the property, entering walls or ceilings, approaching electrical fittings or causing damage around the unit.
If the leak is serious, isolate the water supply to the system if it is safe to do so and call D.R. King Plumbing for urgent assistance.
Should your hot water system be repaired or replaced?
Not every hot water fault requires a new system. In many cases, a failed valve, thermostat, heating component, connection or fitting can be repaired.
Replacement may be more practical when the tank is leaking, corrosion is advanced, replacement parts are unavailable or the existing unit is old, inefficient or no longer suitable for the property.
Our plumbers will assess the condition of the system and provide clear information about the available options.
Factors we consider
- Age and condition of the system
- Location and source of the fault
- Availability of replacement parts
- Condition of the storage tank
- Household or building hot water demand
- Ongoing energy efficiency
- Installation location and available space
- Expected cost of future repairs
Hot water systems we work with
The right system depends on the property, available energy supply, installation space and expected hot water usage.
Electric hot water systems
Electric storage systems are commonly installed in homes, units, offices and commercial properties. We can assist with leaks, valves, connections, installation and system replacement.
Gas hot water systems
Gas systems can provide efficient hot water for residential and commercial applications. Faults may involve gas supply, burners, ignition components, valves, controls or water connections.
Continuous-flow systems
Continuous-flow or instantaneous systems heat water as it is needed. Correct sizing, installation and servicing are important for reliable temperature and flow.
Storage hot water systems
Storage systems hold heated water within a tank. Common problems include tank corrosion, failed valves, leaks, pressure issues and insufficient capacity.
New and replacement hot water system installation
A replacement hot water system needs to be correctly selected and installed for the property. An undersized system may run out of hot water, while an unsuitable installation can create reliability, pressure or compliance problems.
D.R. King Plumbing can help assess the property, existing connections, available installation space and expected demand before recommending an appropriate replacement.
