Is your geyser safe? Warning signs you shouldn't ignore
A geyser mixes water, electricity, heat and pressure — some faults are genuinely dangerous. Call a technician immediately if you notice:
- a mild shock or tingle in the water or on the body — an earthing or element fault
- the geyser tripping the MCB every time it's switched on
- water overheating or steam — a stuck thermostat (an explosion risk)
- continuous leaking from the tank or valve
- a gas smell near a gas geyser
- rusty or smelly water from the hot tap
Don't keep using a geyser showing these signs — switch it off and book a service.
Why you shouldn't DIY a geyser
A geyser combines live electricity with water and a pressurised tank. A wrong fix can cause shocks, short circuits, scalding or a burst tank. Leave diagnosis and repair to a trained technician — it's not a YouTube-tutorial job.
What geyser services can I book?
Complete water-heater care:
- Repair — no heating, leaks, tripping, noise, thermostat, element, PCB
- Servicing — descaling, tank flush, anode and valve check
- Installation — new fitting, uninstallation and shifting
Electric, instant, storage, gas or solar — one app covers it.
How do I book a geyser technician in Kolkata?
Open the Zaruri Hai app, tap Geyser Repair, describe the issue, and pick a slot. A verified technician arrives, diagnoses the fault, and shares the price before any work starts. Booking takes under two minutes.
Common geyser problems we fix — and what causes them
A quick read on the fault:
- No hot water — a failed heating element, faulty thermostat, tripped breaker, or heavy sediment.
- Water leaking — a worn element gasket, a faulty pressure/MFV valve, loose connections, or internal tank corrosion.
- Tripping the MCB — an element short or earthing fault. A safety issue — stop using it.
- Rusty or smelly water — a depleted anode rod or a corroding tank.
- Noise (rumbling/cracking) — sediment and scale on the heating element.
- Slow heating / overheating — scale buildup or a faulty thermostat.
Geyser not heating? Here's why
The most common complaint, usually one of four causes: a burnt heating element, a faulty thermostat, a tripped breaker/fuse, or sediment coating the element so it can't transfer heat. The technician tests each and replaces only what's needed.
Geyser leaking? What it means
First, rule out condensation: wipe the area dry and wait 30 minutes with the geyser off — if no water returns, it's just condensation. A real leak usually means a worn gasket at the element flange, a faulty pressure-release/MFV valve, or — most serious — internal tank corrosion, which often means replacement.
What does a geyser service include?
A full annual service keeps it safe and efficient:
- flush the tank to remove sediment
- descale the heating element
- inspect the anode rod
- test the pressure-relief/safety valve
- check the thermostat and element
- check for leaks and earthing, then test heating
How often should a geyser be serviced?
Once a year is the rule — but Kolkata's hard water leaves heavy mineral deposits, so heavy-use homes benefit from a check every 6–8 months. Regular servicing prevents element failure, low heating and sudden winter breakdowns.
What is the anode rod, and why does it matter?
The anode rod is a sacrificial magnesium rod inside the tank that corrodes instead of your tank — protecting it from rust. When it wears out, you get smelly or rusty water, and the tank itself starts corroding. Replacing a depleted anode rod is cheap and extends your geyser's life by years — yet most services skip checking it. We don't.
Hard water and scaling in Kolkata
Kolkata's water deposits minerals on the element and tank. Over time this scale slows heating, raises bills, causes rumbling noise, and burns out the element. Periodic descaling clears it and keeps the geyser efficient.
Storage or instant geyser — which do you have?
Two designs, serviced differently:
- Storage geyser — a tank (6–25L) that heats and stores hot water; common in bathrooms. More parts (anode, tank, T&P valve) to service.
- Instant/tankless geyser — small (1–3L), heats on demand; common in kitchens. Fewer parts, but element and electrical faults still occur.
We repair and service both, plus gas and solar water heaters.
Should you repair or replace your geyser?
A simple rule:
- Repair if the element, thermostat, valve or gasket has failed — usually cheap and quick.
- Replace if the inner tank is corroded or cracked (rusty water, base leaks) or the unit is very old — a corroded tank can't be safely fixed.
The technician inspects and tells you honestly which is worth it.
Geyser installation, uninstallation & shifting
New installation, plus uninstallation and shifting when you move. We handle secure wall mounting, inlet/outlet pipe connection, correct electrical connection and earthing, fitting the safety/pressure valve, a demo, and safe-use guidance — because a geyser fitted wrong is a hazard.
Geyser safety tips for your home
A few habits keep your geyser safe and efficient:
- set the thermostat to 50–60°C — hotter wastes power and raises scald risk
- switch it off when not in use; don't leave it on all day
- never use a geyser that's leaking, tripping or giving a shock
- get it serviced yearly and the earthing checked
- keep it away from splash zones and direct sunlight
Do you service all geyser brands and types?
Yes — every major brand. AO Smith, Racold, Havells, Bajaj, Crompton, V-Guard, Venus, Usha, Kenstar, Haier, Hindware and more — across electric, instant, storage, gas and solar water heaters. Our technicians are trained on all models.
How much does geyser repair cost in Kolkata?
You see the price upfront — a small service/visiting charge that's adjusted into the bill if you proceed, then a clear estimate after diagnosis. Servicing is fixed-rate; repairs depend on the part.
| Service | Indicative range* |
|---|---|
| Service / visiting charge | ₹199–₹350 (adjusted on repair) |
| General servicing (descale/flush) | ₹400–₹800 |
| Thermostat replacement | ₹400–₹1,000 |
| Heating element replacement | ₹500–₹1,500 |
| Leak / valve repair | ₹300–₹900 |
| Installation | ₹500–₹1,000 |
*Spare parts billed separately. Your exact, live price shows in the app before you confirm.
Do I pay an advance to book?
No advance. You pay after the work is finished and the geyser is heating safely. The service charge is adjusted into the bill once you go ahead with the repair.
Are your technicians verified and skilled?
Yes. Every geyser technician is background-verified and experienced with electrical, plumbing and safety work across brands. You get a professional who diagnoses correctly and fixes it safely — not a risky guess on a live electrical appliance.
Do you use genuine parts and give a warranty?
Yes to both. Any spare — element, thermostat, valve, anode rod, PCB — is a genuine component, and the work carries a 30-day service warranty. If the same issue returns within the window, we revisit free.

Usually a burnt heating element, a faulty thermostat, a tripped breaker or heavy sediment on the element. The technician tests each and replaces only what is needed.
Yes, treat it as a safety issue. It usually means an element short or an earthing fault. Switch the geyser off and book a technician rather than resetting it repeatedly.
Often a depleted anode rod or a corroding tank. Replacing the anode rod is cheap and protects the tank, but a badly corroded tank may need replacing.
Once a year, and every 6–8 months in hard-water areas like much of Kolkata. Servicing includes tank flushing, descaling, and checking the anode rod, valve, thermostat and element.
Repair if the element, thermostat, valve or gasket has failed. Replace if the inner tank is corroded or cracked, which shows as rusty water or base leaks and cannot be safely fixed.
Yes. We service all major brands including AO Smith, Racold, Havells, Bajaj, Crompton and V-Guard, across electric, instant, storage, gas and solar water heaters.
