If your geyser takes longer to heat water than it did last year, your electricity bill has crept up, or you hear a rumbling or popping sound when it heats — you are witnessing Gurgaon's most common geyser problem: limescale buildup from hard water. The good news is that descaling is a simple, affordable service that can fully restore your geyser's performance.
Gurgaon's Hard Water Problem in Numbers
Municipal and borewell water across Gurgaon sectors consistently tests at TDS levels of 400–900 mg/L, with many areas in Sectors 45–57, Palam Vihar, and Manesar testing above 700 mg/L. The BIS safe limit for drinking water is 500 mg/L. When this mineral-laden water is heated above 60°C inside your geyser tank, calcium and magnesium carbonates precipitate as hard white solid deposits — limescale.
How Fast Does Scale Accumulate?
At a TDS of 600 mg/L and a 15L geyser heated twice daily:
- After 6 months: 1–2mm layer on element and tank floor
- After 12 months: 3–4mm layer — element efficiency drops by 15%
- After 24 months (without descaling): 6–8mm layer — element may overheat and fail; safety valve may seize
The popping and rumbling sounds you hear from an old geyser are literally steam bubbles bursting through scale deposits on the heating element — a sign that descaling is overdue.
What Geyser Descaling Involves
- Power isolation: MCB switched off, geyser unplugged, and allowed to cool for 30 minutes.
- Tank draining: Inlet angle valve closed, outlet hot pipe disconnected, tank fully drained via gravity or the safety valve port.
- Heating element removal: The element flange (usually 4–6 bolts) is unscrewed and the element is carefully pulled out. This requires care to avoid cracking the glass tank lining.
- Element acid soak: The element is soaked in a dilute citric acid or acetic acid solution for 20–45 minutes to dissolve calcium carbonate deposits. Scale visibly fizzes and falls off.
- Tank interior flush: The tank is flushed with clean water to dislodge and rinse out loose scale flakes from the bottom.
- Anode rod inspection: The magnesium anode rod (sacrificial anode that protects the tank from corrosion) is inspected and replaced if more than 50% depleted.
- Reassembly and testing: Element is refitted with a new gasket, tank is refilled, and the geyser is tested for heating performance and leakage.
Descaling Cost in Gurgaon
| Service | Cost (PSHomeFix) |
|---|---|
| Standard descaling (element soak + tank flush) | ₹499–₹699 |
| Anode rod replacement (if needed) | ₹200–₹400 |
| New element fitting (if burned) | ₹400–₹700 |
| Safety valve replacement | ₹200–₹350 |
| Full annual service package | ₹799–₹1,099 |
How Often Should You Descale?
- TDS below 300 mg/L: Every 2 years
- TDS 300–600 mg/L: Every 12–18 months
- TDS above 600 mg/L (most of Gurgaon): Every 6–12 months
Pair your descaling schedule with the winter season — October/November before peak cold — to ensure your geyser performs optimally when you need it most.
