CHECK YOUR WATER'S
TDS LEVEL FREE.
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
What your TDS number means.
What is TDS in water?
TDS means Total Dissolved Solids - the mineral load in your water, measured in ppm.
In most Indian homes, that usually means calcium and magnesium scale building up on the appliances you heat water in most often.
Above roughly 300 ppm, the maintenance problem becomes visible quickly enough that routine descaling starts to matter.
What hard water slows down first.
Washing Machine
Scale coats the heating element and drum, pushing energy use up and performance down over time.
Kettle
White crust shows up fast, boil times stretch out, and flakes start showing in hot water.
Geyser / Water Heater
Scale acts like insulation on the element, so heating slows and electricity use rises.
HOW ACCURATE IT IS
Good for planning. Not pretending to be a lab test.
The OrangeDemon database gives representative TDS values for your area. That is enough to judge how aggressive your hard-water maintenance needs to be.

Good for deciding whether you need monthly or quarterly descaling
A handheld meter is still best if you need an exact building-level reading
COMMON QUESTIONS
TDS check - answered.
What does 360 ppm TDS water mean?+
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.
What does 430 TDS water mean?+
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.
Is 270 ppm TDS water safe and hard?+
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.
How do I check my TDS without a meter?+
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.
Is there a free online TDS checker for India?+
Yes - this page. Enter your 6-digit pincode or city name above to get your area's TDS in ppm, hardness tier (Low / Moderate / High / Extreme / Very Extreme), and recommended descaling schedule for your appliances. No registration needed.
