Enter your pincode or city name. Get your area's TDS in ppm, your hardness tier, and exactly what it means for your washing machine, kettle, and geyser.
TDS (Total Dissolved Solids) measures dissolved minerals like calcium and magnesium in your water. Above 300 ppm, these minerals visibly scale onto appliances and surfaces — shortening their lifespan and reducing efficiency.
REFERENCE GUIDE
Soft water. Light scale over 3–6 months. Biannual maintenance is sufficient.
Scale visible in kettles within 2–3 months. Quarterly descaling recommended.
Fast scale. Washing machine elements and kettle elements at risk within 12 months without treatment.
Aggressive scale. Appliances will show efficiency loss within a year. Element failure risk by year 2–3.
Industrial-level mineral load. Common in Rajasthan, Gujarat desert zones. Appliances need treatment every 2–3 weeks.
TDS stands for Total Dissolved Solids — a measurement of all dissolved minerals, salts, and compounds in water, expressed in mg/L or ppm (parts per million). They are the same unit.
The primary minerals in Indian hard water are calcium and magnesium carbonates. When water evaporates or is heated, these minerals precipitate out of solution and bond to surfaces — this is called limescale or scale.
Most Indian cities have TDS between 300–700 ppm due to borewell and groundwater dependency. European cities average 50–200 ppm. This is why Indian appliances scale 3–10× faster than the same appliances used abroad.
Washing Machine
Scale coats the heating element and drum. Efficiency drops within 6–12 months at 400+ ppm. Element failure risk by year 3–4.
Kettle
Fastest to scale. White crust visible within weeks at 500+ ppm. Boil time increases as scale builds — a measurable monthly change.
Geyser / Water Heater
Scale on the element acts as thermal insulation. Heating slows. Electricity use rises. Rumbling noise is scale cracking under heat stress.
The OrangeDemon database contains representative TDS values measured at 4,940 pincodes across India. Values are averages — actual readings can vary by building, floor, and whether your building uses municipal supply or a private borewell. For an exact number, purchase a TDS meter (available on Amazon for ₹200–₹500) and test your tap directly.
The city-level data is sufficient to know whether your area has a hard water problem and which maintenance schedule to follow. Most residents don't need the pinpoint accuracy of a handheld meter — they need to know whether to descale monthly or quarterly.
COMMON QUESTIONS
360 ppm is moderate-to-high hardness — common in Punjab, Haryana, and many UP districts. Your kettle will show white scale within 2–3 months of regular use. Quarterly descaling prevents buildup from hardening into crust. Not an emergency, but regular maintenance is needed.
430 ppm is HIGH hardness. Kettle scaling visible within 5–8 weeks. Washing machine element and drum accumulate deposits within 6 months. Monthly descaling is the correct maintenance interval. This is typical of NCR, central Haryana, and many central Indian cities.
270 ppm is MODERATE hardness. Light scale forms over several months but is easily managed. Biannual or quarterly descaling is sufficient. This level is typical of Punjab foothills, Chandigarh, and northern UP districts near the Himalayan water table.
You can use the OrangeDemon database here — search your pincode or city to get a representative TDS reading for your area. Without a meter and without this tool, the best indicators are: how fast your kettle scales (fast = high TDS), whether there are white marks on taps and shower glass, and how hard it is to lather soap in the shower.

FULL DATABASE
Every city in our database has its own hard water guide with TDS data, appliance impact, and a tailored descaling schedule.
NOW AVAILABLE
Triple-acid powder sachet. Citric, tartaric, and malic acid — all food-grade. One cycle dissolves calcium and magnesium deposits from washing machines, kettles, and geysers. Effervescent reaction confirms it's working.

TDS — Total Dissolved Solids — measures the concentration of minerals like calcium and magnesium in your water, in mg/L (ppm). Most Indian cities sit between 300 and 900 ppm due to borewell and groundwater sources. Above 400 ppm, these minerals visibly scale onto surfaces and appliances, shortening their lifespan and reducing efficiency.
