How do I maintain my geyser?

[Updated 7 May 2025)]

We are often asked: “How can I maintain my geyser? There are no moving parts!”

The truth is that most standard electric geysers in South Africa can and should be maintained. In addition to a plumber inspecting the components and checking for compliance, one crucial part to monitor is the anode. This self-sacrificing rod plays a vital role in preventing corrosion. As it deteriorates over time, it loses its ability to protect the geyser—making regular replacement essential, typically every year or so.

Maintenance

It’s important to start this maintenance early. Geyser experts advise that if the anode isn’t replaced within the first year of installation, it may corrode to the point where its threads are rusted and fused. Attempting to remove it at that stage could cause further damage. In short, delaying the first replacement may make future maintenance impossible.

Geysers serviced every 12 to 18 months tend to last significantly longer. Claims history consistently shows that schemes which follow proactive maintenance practices experience fewer failures than those that neglect regular servicing. In terms of sectional title ownership, prescribed rules place the responsibility of geyser maintenance squarely on the owner. This responsibility extends far beyond just replacing the anode.

During a service, several additional checks should be performed:

• Verify the geyser’s temperature setting.
• Inspect for leaks on the geyser and surrounding pipes.
• Check pressure valves.
• Examine the heating element for scale or mineral buildup.
• Ensure pipe insulation is intact—wind and weather can easily dislodge it.

Some geysers, such as copper or stainless-steel models, do not require anodes. These types often have stainless steel threaded connections for the element and thermostat, making maintenance much simpler and more cost-effective.

Whose responsibility is it?

Every scheme has its dynamics. In some cases, trustees may find it easy to arrange regular geyser servicing; in others, this may be logistically challenging. Where feasible, we encourage managing agents to educate trustees and owners about anode maintenance and to consider higher-specification alternatives, such as stainless-steel geysers, which offer better long-term value and reliability.

A more proactive approach to maintenance can significantly reduce the risk of damage and extend the life of each geyser unit. Talk to your managing agent, insurance broker and geyser specialist – there are ways to make a huge difference!
