A burst geyser is every homeowner's nightmare—usually happening at 2 AM on a Sunday, resulting in flooded ceilings, ruined carpets, and icy showers. But most geyser failures aren't sudden accidents; they act as the final straw after years of neglect.
At Construction Joburg, we believe in proactive maintenance. You can prevent 90% of failures by understanding how your system works and what to look out for.
The DIY Check: What You Can Do
While we don't recommend opening the electrical panel yourself, you can perform these visual checks safely:
- Listen: A healthy geyser hums. If you hear hissing, popping, or boiling sounds, your element or thermostat may be struggling.
- Look for Drips: Check the overflow pipe outside. A constant steady drip (more than the usual expansion relief) often signals a faulty pressure control valve.
- Check the Tray: If your geyser is in the roof, pop your head into the trapdoor (safely). Is the drip tray dry? If there's water in it, you already have a slow leak that needs immediate professional attention.

The Expert Fix: What We Do
To truly extend your geyser's life, you need a professional service every 18-24 months. Here is what our qualified plumbers check:
- The Sacrificial Anode: This metal rod is designed to corrode instead of your tank. Once it's gone, rust attacks the tank itself. Replacing this R300 part can save you from replacing a R5000 geyser.
- Vacuum Breakers: These prevent your geyser from imploding when water pressure drops (common during municipal water cuts). We ensure they aren't seized.
- Thermostat & Element: We test efficiency. An old element coated in limescale uses significantly more electricity to heat the same amount of water.
