Water dripping from your bathroom geyser is a high-priority concern that demands careful handling. Because electric water heaters combine water under pressure with 230V mains electricity, distinguishing between normal pressure discharge and serious tank failure is critical for household safety.
Typical mechanical and environmental triggers
As cold water heats to 65°C, it expands in volume, raising internal tank pressure. The spring-loaded pressure relief valve (usually with a small lever on the cold inlet pipe) is designed to drip small droplets during heating to prevent tank over-pressurization.
Flexible stainless steel braided hoses connect your wall plumbing to the geyser. Over time, internal rubber washers harden or hex nuts corrode, causing steady dripping down the outside of the pipes.
The heating element is bolted into the bottom of the inner tank with a rubber or silicone sealing gasket. Heat cycles and hard water minerals degrade this seal, allowing water to seep past the element mounting plate into the electrical cover.
Hard water salts cause galvanic pitting on the inner tank welds. Once the sacrificial magnesium anode rod dissolves completely, hard water attacks the steel tank wall, eventually causing pinhole corrosion leaks.
Basic troubleshooting before requesting service
Observe carefully: Is water dripping from the small spout on the pressure relief valve? From the threaded brass nut on the flexible hose? Or directly through the electrical plastic bottom cover?
If a few droplets drip exclusively while the water is actively heating and stops when the thermostat turns off, the safety pressure valve is operating normally.
Locate the small angle cock valve on the bathroom wall connected to the geyser cold pipe. Turn it clockwise to stop incoming water pressure.
Safety warnings & high-risk DIY mistakes
Our local technician visits your residence across any sector of Gurgaon with multimeters, pressure gauges, and diagnostic tools. The ₹199 inspection fee is adjusted directly into your final bill upon repair approval.
Yes, occasional dripping (a few spoonfuls per heating cycle) from the safety valve spout during active water heating is completely normal pressure relief.
Internal glasslined or enamel-coated storage tanks cannot be reliably welded once corroded. If the inner tank has rusted through, complete geyser replacement is necessary for safety.
Turn off the electrical switch and trip the bathroom MCB. Then turn off the wall inlet water angle cock valve to isolate both electrical and water supplies.

Stepping into the shower during chilly Gurgaon winter mornings only to find lukewarm or freezing water is a miserable start to the day. Electric water heaters (geysers) operate under heavy electrical load, where hard water minerals and thermal safety cutouts frequently cause heating failure.
