At 911 Drain & Plumbing, we see geyser problems all over Pretoria East. In Garsfontein, Moreleta Park, Faerie Glen, and Silverwoods, the causes are surprisingly common, and knowing what to look for can save you a lot of stress.
Common Reasons Your Geyser Might Not Be Heating
1. Tripped or faulty thermostat
If the thermostat malfunctions, your geyser may stop heating water or heat it inconsistently. This is a common issue in older units around Garsfontein homes.
2. Heating element failure
Electric geysers rely on heating elements that wear out over time. When the element fails, your geyser may not heat at all or struggle to reach the set temperature.
3. Sediment build-up
Hard water areas like Pretoria East often see sediment collecting at the bottom of the geyser. This can cover the heating element and reduce efficiency, leaving you with lukewarm water.
4. Pressure valve issues
A faulty or leaking pressure relief valve can prevent the geyser from heating properly. This is a safety feature, so it’s important to have it checked by a professional rather than trying a DIY fix.
5. Electrical supply problems
Sometimes the problem isn’t the geyser itself but the power supply. Faulty wiring, tripped breakers, or blown fuses can all stop your geyser from heating.
Quick Checks Before You Call a Plumber
- Make sure the breaker for the geyser hasn’t tripped.
- Check the pressure relief valve for leaks or dripping.
- If your geyser has a reset button, press it and see if the water heats.
- Observe if hot water reaches all taps or just some, which can indicate pipe issues.
How 911 Drain & Plumbing Fixes Geysers in Pretoria East
We handle all types of geyser problems, from element replacements and thermostat repairs to full geyser installations. Last week, we were called out to a Garsfontein home where the geyser had stopped heating entirely. After inspection, we replaced the heating element and flushed out the sediment. The client had hot water again within a couple of hours.
We use the right tools and expertise to make sure your geyser is safe, efficient, and reliable. Learn more about our geyser services for Pretoria East homes.
