With the arrival of winter, households increasingly rely on hot water for daily domestic tasks such as bathing, washing clothes, and cleaning utensils. After remaining completely inactive through the summer and rainy seasons, water heaters are often turned back on without a second thought. However, switching on an uninspected geyser after several months of disuse can pose severe safety risks. Over time, internal electrical wiring, connecting pipes, safety valves, and heating elements can undergo degradation, leading to unforeseen hazards.
Failing to perform routine preliminary checks can trigger electrical short circuits, water leakages, electric shocks, or even dangerous pressure build-ups inside the storage tank. In addition to ensuring household safety, regular seasonal checks optimize energy efficiency and prolong the operational lifespan of the appliance. Before turning on your geyser for the first time this winter, following four essential inspection steps will guarantee both safety and performance.
Inspect Electrical Wiring, Plugs, and Grounding Systems
A water heater is a high-power electrical appliance that functions in high-humidity areas like bathrooms. Because water conducts electricity, even a minor electrical fault can escalate into a life-threatening hazard. Before turning on the power switch, inspect the power cable thoroughly for visible cracks, cuts, or signs of rodent damage. Check the plug and power socket for any discoloration, burn marks, or melted plastic.
Equally critical is ensuring proper grounding or earthing in your home electrical system. Poor grounding can lead to electric current leaking directly into the running water. If you notice loose connections, sparking inside the wall switch, or any burning smell, do not turn on the appliance and immediately consult a qualified electrician.
Check Pipe Connections, Valves, and Potential Water Leaks
Prolonged inactivity can cause rubber washers, metal joints, and inlet/outlet pipes to degrade, rust, or crack. Before connecting the appliance to the electrical outlet, carefully check every pipe joint attached to the unit. If you spot dripping water, moisture buildup, or visible corrosion around the connections, address these issues promptly.
Additionally, pay close attention to the pressure relief valve, commonly known as the safety valve. This safety component releases excessive internal tank pressure to prevent catastrophic structural damage or explosions. If water leaks continuously from the safety valve, or if it appears clogged with rust, seek assistance from a certified service technician.
Ensure the Tank is Fully Filled Before Powering On
One of the most critical operational rules for any water heater is never running it on an empty tank. Powering on an empty geyser will burn out the heating element within seconds, potentially causing permanent damage and fire risks. Prior to turning on the electrical supply, open the main water line feeding the geyser.
Next, open the hot water tap inside the bathroom to vent trapped air from the system. Wait until a steady, uninterrupted flow of water streams out of the tap. Once you confirm that the water tank is completely filled and there are no external leaks, it is safe to turn on the power switch. Never attempt to run the geyser if the main water supply is interrupted.
Clean Mineral Deposits and Schedule Professional Servicing
In areas with hard water, mineral deposits gradually accumulate on the inner walls of the tank and around the heating element, forming a thick white scale layer. During months of non-use, these deposits harden, severely reducing the heating efficiency of the appliance. If your geyser takes significantly longer to heat water or produces unusual popping or humming sounds during operation, mineral buildup is the likely cause.
Never attempt to open the outer casing or disassemble internal components yourself while the unit is connected to the mains. Self-cleaning carries significant electrical risks and can void product warranties. Hire an authorized technician to perform a deep internal cleaning and descaling service to restore optimal performance.
