A common household concern is a faulty geyser, especially when you discover a geyser leaking from overflow pipe. This issue often indicates a problem with the thermostat regulating water temperature within your electric water heater. Ignoring a leaking overflow pipe, particularly in areas like Johannesburg where water conservation is vital, can lead to significant water waste and increased utility bills. Understanding how these systems function allows homeowners to tackle minor issues before needing professional assistance from a qualified plumber.

Geyser Overflowing? Quick Fixes & Prevention Tips Inside!
This guide provides practical advice for addressing a geyser (water heater) leaking from the overflow pipe and offers strategies for preventing future occurrences. A consistent leak can waste water, increase utility bills, and potentially damage your property. Let’s explore how to troubleshoot and resolve this issue.
Understanding the Geyser Overflow Pipe
The overflow pipe on your geyser is a crucial safety mechanism. It’s designed to release excess water pressure or volume, preventing the geyser from potentially bursting. When water continuously flows from this pipe, it indicates an underlying problem that needs immediate attention.
Why is My Geyser Leaking from the Overflow Pipe?
Several reasons can cause your geyser to leak. Understanding the cause is the first step towards finding a solution.
-
Excessive Water Pressure: High water pressure from the municipal supply can overwhelm the geyser’s capacity.
-
Faulty Temperature & Pressure (T&P) Relief Valve: This valve is designed to release pressure and temperature when they exceed safe levels. If it malfunctions, it might release water prematurely or constantly.
-
Thermostat Issues: A malfunctioning thermostat can cause the water inside the geyser to overheat, leading to excess pressure and water discharge through the overflow pipe.
-
Expanded Water Volume: As water heats up, it expands. If there’s no space for this expansion, the excess water is forced out through the overflow. This can be more pronounced in closed systems without an expansion tank.
-
Air Lock in the System: Air trapped in the water lines can sometimes cause pressure fluctuations that trigger the overflow pipe.
Quick Fixes for a Geyser Leaking from Overflow Pipe
Before calling a professional, try these simple troubleshooting steps.
-
Check Your Water Pressure: Use a water pressure gauge (available at most hardware stores) to measure the water pressure entering your home. It should ideally be between 40 and 60 PSI.
-
Inspect the T&P Valve: Carefully examine the T&P valve for signs of corrosion or damage. Lift the test lever on the valve. If the valve doesn’t reseat properly after releasing the lever and continues to leak, it likely needs replacement. Caution: Hot water will discharge when you lift the lever. Take necessary precautions.
-
Lower the Thermostat Setting: Reduce the geyser’s thermostat temperature. A lower setting might alleviate excessive pressure caused by overheating.
-
Check for Air in the Pipes: Sometimes, running all the hot water taps in your house for a few minutes can help clear trapped air from the system.
Prevention Tips to Stop Leaking from Overflow Pipe
Preventing a geyser from leaking is often simpler and cheaper than fixing a major problem. Implementing these practices can extend the life of your geyser and save you money.
Regular Geyser Maintenance
Regular maintenance is key. Schedule annual inspections by a qualified plumber.
-
Flush the Geyser Annually: Flushing removes sediment buildup that can affect the geyser’s efficiency and potentially damage components.
- Turn off the power to the geyser.
- Turn off the cold water supply.
- Connect a garden hose to the drain valve near the bottom of the geyser.
- Run the hose to a safe drainage area.
- Open the drain valve and allow the geyser to completely drain.
- Flush with cold water until the water runs clear.
- Close the drain valve and refill the geyser with cold water before turning the power back on.
-
Inspect the Anode Rod: The anode rod protects the geyser tank from corrosion. Have it inspected and replaced every few years.
Water Pressure Regulation
High water pressure is a common culprit.
- Install a Pressure Reducing Valve (PRV): A PRV regulates the water pressure entering your home, preventing excessive pressure from reaching the geyser. This is crucial if your incoming water pressure is consistently above 60 PSI.
Expansion Tank Installation
An expansion tank accommodates the expansion of water as it heats, preventing pressure buildup.
- For Closed Systems: If your plumbing system is a closed system (meaning it has a backflow preventer that prevents water from flowing back into the municipal supply), installing an expansion tank is highly recommended. The size of the expansion tank will depend on the size of your geyser. Consult with a plumber for proper sizing and installation.
Monitoring and Prompt Action
Pay attention to any unusual signs or sounds coming from your geyser.
- Listen for Unusual Noises: Gurgling, popping, or hissing sounds can indicate problems that need attention.
- Check for Leaks Regularly: Periodically inspect the area around the geyser for signs of leaks.
- Don’t Ignore the Overflow: If the overflow pipe is constantly dripping or flowing, address the issue promptly to prevent further damage.
By following these quick fixes and prevention tips, you can minimize the risk of your geyser leaking from the overflow pipe, ensuring its longevity and saving on unnecessary water and energy costs. If you are uncomfortable performing any of these tasks, consult a qualified plumber.
Geyser Overflowing? FAQs
Here are some frequently asked questions regarding geyser overflows and what you can do to prevent them. We hope this helps clarify some common concerns.
Why is my geyser constantly leaking from the overflow pipe?
A geyser constantly leaking from the overflow pipe usually indicates a problem with the thermostat, a buildup of pressure, or a faulty pressure release valve. The thermostat might be failing to shut off the heating element, causing the water to overheat and expand. This excess pressure then gets released through the overflow.
Can I temporarily stop the geyser from overflowing myself?
You can try turning off the geyser at the main switch. This will stop it from heating further and potentially reduce the overflow. However, this is only a temporary solution. It’s crucial to identify the underlying cause to prevent future occurrences and potential damage. Contact a qualified plumber for a lasting fix.
What are the risks of ignoring a geyser leaking from overflow pipe?
Ignoring a geyser leaking from overflow pipe can lead to several problems. Firstly, it wastes water and increases your water bill. Secondly, the constant dripping can damage ceilings, walls, and flooring. Most importantly, a malfunctioning geyser can pose a safety risk, potentially leading to burns or even an explosion due to excessive pressure.
How can I prevent my geyser from overflowing in the future?
Regular maintenance is key. Schedule a professional inspection at least once a year to check the thermostat, pressure release valve, and heating element. Ensure proper ventilation around the geyser and consider installing a temperature and pressure relief valve. Addressing minor issues promptly can prevent major problems like a geyser leaking from overflow pipe.
So, there you have it! Hopefully, you’re now a little more confident tackling a geyser leaking from overflow pipe. Remember to always prioritize safety and don’t hesitate to call a professional if things get tricky. Good luck!
