A faulty geyser is most often caused by a failed thermostat, a faulty heating element, or corrosion inside the tank. We specialise in diagnosing these specific faults to restore your hot water supply safely and in line with compliance standards for Randburg residences.
Identifying a Failing Geyser
A geyser rarely fails without providing clear warning signs. Recognising these indicators allows for preventative action, protecting your home from the significant water damage that a catastrophic tank failure can cause to ceilings, wiring, and structural supports.
Key indicators that your geyser requires an immediate diagnostic assessment include:
- Water constantly dripping or running from the overflow pipe outside your home.
- No hot water, or water that is only lukewarm and runs out quickly.
- The dedicated geyser circuit breaker on your distribution board trips repeatedly.
- Audible humming, hissing, or banging noises coming from your roof space.
The Root Cause of Geyser Failure
Most geyser issues in Randburg homes stem from component fatigue or mineral build-up. The water quality in parts of Gauteng can accelerate limescale accumulation on the heating element and thermostat probe. This insulation effect forces the components to work harder, leading to reduced efficiency and eventual failure.
The Critical Role of Safety Valves
The Temperature and Pressure (T&P) Valve is a non-negotiable safety device, not an operational component. If the thermostat fails and the geyser overheats, this valve is designed to release excess pressure. A seized or faulty valve can result in the geyser tank rupturing with extreme force, causing severe property damage.
Professional Geyser Repair and Installation
Our certified technicians perform a complete system diagnostic to determine if a repair is a safe and viable long-term solution. In some cases, a full replacement is the more responsible and cost-effective option, particularly if the integrity of the geyser tank itself is compromised.
Our standard geyser service protocol is designed to ensure safety and compliance:
- A full inspection of the geyser tank for corrosion, the element, and the thermostat.
- Verification that the installation meets SANS 10254 standards, including a correctly installed drip tray and overflow piping.
- Testing of all electrical connections and ensuring the correctly rated circuit breaker is installed.

FAQs
How often should a geyser be serviced?
We recommend a full geyser service every 2 to 3 years. This preventative maintenance involves draining the tank, cleaning out sediment, checking the sacrificial anode rod which prevents corrosion, and testing all safety components to prolong its operational lifespan.
Why is my geyser tripping the power?
This is almost always due to a failed heating element. Water has likely penetrated the element’s outer sheath, causing a direct electrical short circuit when it tries to heat up. This is a fire hazard and requires immediate replacement by a qualified technician.
Is a leaking geyser an emergency?
Yes. Any persistent leak indicates a potential tank failure or a compromised safety valve. You should immediately switch the geyser off at your main distribution board and shut off the cold water supply valve to the unit before calling a professional plumber for an emergency call-out.
