New geyser installed? Learn essential maintenance tips for South African homes to improve efficiency, extend lifespan, and prevent costly breakdowns before problems start.

How to Maintain a Geyser After Installation
A geyser is an essential appliance in most South African homes, providing hot water for daily activities like bathing, cooking, and cleaning. Once installed, it's easy to forget about your geyser until something goes wrong. However, regular maintenance is crucial to ensure it operates efficiently, lasts longer, and avoids costly repairs. In this guide, we'll walk you through practical tips on how to maintain your geyser after installation, helping you save money and avoid unnecessary headaches.
Why Geyser Maintenance is Non-Negotiable
Your geyser is probably out of sight and out of mind... until it stops working. Proactive maintenance is the best way to prevent that dreaded cold-shower surprise. Here's why it's so important.
Extend the Lifespan of Your Geyser
A standard geyser can last anywhere from 5 to 15 years, but its lifespan is heavily influenced by maintenance. Regular servicing helps combat the two biggest enemies of any geyser: corrosion and sediment build-up. By keeping these in check, you can significantly prolong the life of your unit.
Improve Energy Efficiency (and Save on Electricity Bills)
Your geyser is one of the biggest energy consumers in your home. Over time, sediment from your water supply can build up at the bottom of the tank and coat the heating element. This forces the element to work harder and longer to heat the water, causing your electricity bill to creep up. A clean, well-maintained geyser is an efficient geyser.
Prevent Catastrophic Failures (and Water Damage)
A burst geyser can cause devastating water damage to your ceilings, walls, floors, and furniture. Regular maintenance involves checking crucial safety components, such as the Temperature and Pressure (TP) valve and the anode rod, which are designed to prevent the tank from overpressurizing or corroding from the inside out.
Ensure Consistent Hot Water Supply
Is your water not as hot as it used to be? Or does it run out faster than before? These are often early signs that your geysers need servicing. Maintenance ensures the thermostat is calibrated correctly and the heating element is functioning optimally, providing you with the consistent hot water you expect.
Your Geyser Maintenance Checklist: DIY vs. Professional Tasks
Maintaining your geyser is a team effort between you and a qualified plumber. Here's a breakdown of what you can do yourself and when it's time to call in a Kandua Pro.
Simple DIY Checks You Can Do Regularly (Monthly)
These quick checks don't require any special tools and can help you spot a problem before it gets serious.
- Visual Inspection: Take a look at your geyser and the surrounding area. Look for any signs of dripping water, rust spots on the tank, or dampness on the ceiling or walls below.
- Listen for Strange Noises: A healthy geyser should be relatively quiet. If you start hearing popping, banging, or rumbling sounds, it's often a sign of sediment build-up being heated at the bottom of the tank.
- Check the Drip Tray and Overflow Pipe: Your geyser should be sitting in a drip tray with an overflow pipe leading outside. Check that the tray is dry and the pipe isn't constantly dripping. A slow, occasional drip from the overflow is standard as the water heats and expands, but a steady stream means there's a problem.
- Test the Temperature and Pressure (TP) Valve: This is a critical safety feature. CAUTION: The water that comes out will be very hot. Carefully lift the lever on the TP valve for a few seconds. A short burst of water should come out of the overflow pipe. If it doesn't, or if it continues to leak after you release the lever, the valve may need to be replaced by a professional.
Essential Maintenance Best Left to the Professionals (Every 2-3 Years)
These tasks are more complex and require the expertise and tools of a qualified plumber. We strongly recommend booking a Kandua Pro for a full geyser service every 2 to 3 years (or more frequently if you live in a hard water area).
- Draining the Geyser to Remove Sediment: A plumber will safely drain the entire tank to flush out all the accumulated sediment and mineral scale. This immediately improves efficiency and reduces strain on the heating element.
- Inspecting and Replacing the Anode Rod: The anode rod is a "sacrificial" metal rod inside your geyser tank. Its job is to attract corrosive elements in the water, essentially sacrificing itself to protect the tank lining. Once it's depleted, the tank itself will start to corrode. A plumber will inspect it and replace it if necessary.
- Checking the Thermostat and Heating Element: A professional will check that the thermostat is accurate and that the heating element is clean and functioning correctly. They can replace these components if they are faulty or worn out.
- Inspecting All Electrical Connections: Faulty wiring is a serious safety hazard. A plumber will ensure all electrical components are secure, insulated, and up to code.
Warning Signs: When to Call a Kandua Pro Immediately
Some issues can't wait for a scheduled service. If you notice any of the following, turn off the power to your geyser at the main distribution board (DB) and call a professional right away:
- Water is leaking from the geyser tank itself.
- A complete lack of hot water.
- The circuit breaker for the geyser keeps tripping.
- Loud banging or rumbling noises from the tank.
- Discoloured or rusty-looking hot water.
- A continuous, steady flow of water from the overflow pipe.

Frequently Asked Questions (FAQs)
How much does a professional geyser service typically cost?
The cost can vary depending on your location, the type of geyser, and the services included. A standard service might range from R600 to R1500. If parts like the anode rod, element, or thermostat need to be replaced, the cost will be higher. It's always best to get a few quotes.
My overflow pipe is dripping. Is this normal?
A slow, intermittent drip is standard, especially when the geyser is actively heating water (due to thermal expansion). However, if you see a constant, steady stream of water, it usually indicates that the TP valve or another component is faulty and needs immediate attention from a plumber.
Can I install a geyser blanket myself to save energy?
Yes, installing a geyser blanket is a great DIY project that can reduce heat loss by 25%-45%. Be sure to follow the manufacturer's instructions carefully and do not cover the thermostat, control panels, or the TP valve.
How long should a geyser last in South Africa?
With regular maintenance, a good quality geyser should last between 10 and 15 years. Without maintenance, its lifespan could be cut in half, especially in areas with hard water.
What exactly is an anode rod, and why is it so important?
The anode rod is a metal rod (usually magnesium or aluminium) that screws into the top of your geyser tank. It protects the tank from rust by attracting corrosive particles in the water through an electrochemical process. It's designed to be "sacrificed" over time, and replacing it is far cheaper than replacing the entire geyser.
Does my home insurance cover a burst geyser?
Most building insurance policies in South Africa do cover damage from a burst geyser. However, some insurers may reject a claim if they find the geyser was not properly maintained. Regular servicing provides a record of responsible ownership. Always check the specifics of your policy.
How can I save electricity with my geyser, especially with loadshedding?
Besides regular maintenance and installing a geyser blanket, you can install a timer only to heat the water when you need it. Setting the thermostat to 60°C is also ideal for balancing energy efficiency and preventing bacterial growth.

What Your Garage Door Motor Actually Does (And Why It Breaks)
Spoiler alert: your garage door motor isn't actually doing the heavy lifting. The torsion springs carry almost all the weight. The motor simply pushes, pulls, controls the descent so it doesn't slam, and acts as a lock when the door is shut. That’s why a relatively small box on your ceiling can move such a massive door. Want to test this? Pull the red manual release cord and lift the door by hand. If it glides up easily and stays put when you let go, your springs are doing their job, and the fault lies with the motor. If the door feels like dead weight or slams back down- stop. You’ve got a spring problem.
