As the crisp Alberton mornings start to settle in, we all begin to rely a little more on that morning hot shower. But in Gauteng, winter isn't just tough on us - it's the ultimate stress test for your geyser.
Most geyser "catastrophes" are completely preventable with a simple service.

Here are the three red flags you should look for before the first big frost hits.
- The "Rusty Tap" Warning: If you turn on your hot water and notice a reddish-brown tint or a metallic taste, your geyser is trying to tell you something. Every electric geyser has a sacrificial anode—a magnesium rod designed to "sacrifice" itself to corrosion so your steel tank doesn't rust.
Once that rod is gone, the rust starts eating your tank. Replacing an anode costs a fraction of a new geyser installation, but if you wait until the tank leaks, it’s usually too late.
- Strange "Rumbling" or "Popping" Noises: Does your geyser sound like a kettle boiling or make strange banging noises in the roof? This is usually a sign of sediment and limescale build-up.
Over time, minerals in our water settle at the bottom of the tank, burying the heating element. When the element turns on, it has to heat through that "mud" first, which causes the water trapped underneath to boil violently. Not only does this waste massive amounts of electricity, but it also causes the element to burn out prematurely.
- The "Drip-Drip" on the Ceiling: If you see damp patches on your ceiling or notice water constantly running from the overflow pipe outside, your Pressure Control Valve (PCV) or Temperature & Pressure (T&P) valve might be failing.
In winter, the extreme temperature difference between the freezing intake water and the boiling tank creates internal pressure. If your valves are seized or faulty, that pressure has nowhere to go - and that's when geysers burst.
