A Puryn water softener is a tank of ion-exchange resin fitted where water enters the building. It takes out the calcium and magnesium that scale geysers, taps and showers, and it regenerates with common salt. Five manual sizes from 1,000 to 9,000 LPH; automatic from 1,000 to 6,000 LPH. You need one when hardness is above 200 mg/L, the IS 10500 acceptable limit, and your lab report tells you if yours is.
Hardness changes the salt, not the size. Size the softener by how many taps run at once. Your hardness decides how often it regenerates and how much salt it uses.
Four signs: white scale on taps and showers, spots on utensils and tiles, dry skin and stiff hair, and geysers and washing machines that fail early. Orange stains or a salty taste are different problems with different fixes.
White crust chokes the flow and ruins fittings.
Utensils, glassware and tiles wear a chalky white film.
Soap will not lather; hair feels stiff after a wash.
Scale builds up on heating elements and inside pipes.
Rusty marks on basins and buckets.
High TDS, common in coastal wells.
We test hardness, TDS, iron and pH at your tap for free, and count how many outlets run at once. If your hardness is under 200 mg/L we will tell you that you do not need a softener.
A softener is a plumbing fix for hard water, not a drinking-water treatment. Under IS 10500:2012 the acceptable limit for total hardness is 200 mg/L as CaCO3, and 600 mg/L is the outer limit where no other source exists. Below 200 you generally do not need one. Between 200 and 400 you will see scale and stiff laundry. Above 400 the damage to geysers and washing machines is fast.

Size by your peak flow: how many showers and taps run at the same time. 1,000 LPH is about 16.7 litres a minute, enough for one shower and a tap together. A shower draws 8 to 10 litres a minute, a tap 4 to 6. Your hardness then decides how often it regenerates, not which size you buy.

The LPH is how much soft water the unit can deliver at once. Undersize it and the pressure drops exactly when everyone is getting ready in the morning.
More resin means more litres between regenerations. At 300 mg/L, 25 L of resin gives about 4,600 litres before it needs salt.
Softeners on this valve are rated to 2 bar. We check your pump pressure during the test, and fit a regulator if it is higher.

Both use the same resin and salt. The difference is who starts the regeneration. If it works out to once a week or less, manual is fine. If your water needs it every two or three days, automatic saves you from forgetting.
Top-mounted manual multiport valve and a separate brine tank. You turn the valve to regenerate when it is due. No power needed for the valve.
A programmed multiport valve runs the regeneration on schedule. You still top up the salt and we check the settings at service visits.
One product page covers every size. Tell us your hardness and your peak flow, or let us measure them, and we quote the right capacity with installation.
Move the sliders. Your hardness and the number of people decide how many days you get between regenerations and how much salt you use in a month.
How it works: standard softening resin takes up about 55 g of hardness (as CaCO3) per litre before it needs salt, so litres between regenerations = resin litres × 55,000 ÷ hardness. Daily use is the BIS / CPHEEO norm of 135 litres a person. Salt per regeneration is from the Puryn manual softener specifications. Real figures depend on your water and habits; we confirm them with your lab report.
Iron fouls softening resin and shortens its life. A softener removes only a little iron, at the cost of the resin. Where water stains sinks orange, an iron removal stage belongs before the softener, not instead of it. Acidic water gets pH correction before both.
The softener sits on the line from the pump to the overhead tank, so every tap, shower and appliance gets soft water. Our technicians fit it with a bypass, so water keeps flowing during regeneration and service.
Already have a softener that has stopped working? The resin may be exhausted or fouled by iron. See filter media replacement.
Have a lab report or a hardness strip reading? WhatsApp it with the number of bathrooms in your home. A person from our water team tells you the size and whether manual or automatic suits you.
Hardness, iron if you know it, and how many bathrooms or outlets run at once.
Peak flow for the size, hardness for the regeneration interval and salt.
We measure at your tap before any quote.
We test hardness, TDS, iron and pH, check your pump pressure, and size the softener to your home. Both lab reports are included in your price.
Water with high dissolved calcium and magnesium. It leaves white scale on taps and appliances and makes soap less effective. IS 10500 sets the acceptable limit at 200 mg/L as CaCO3.
A softener swaps calcium and magnesium for sodium, so softened water carries a little more sodium and is not treated for bacteria, nitrate or dissolved solids. Soften the house supply and use a Puryn purifier (e1 to e6) for drinking water.
No. It exchanges one set of ions for another, so total dissolved solids stay about the same. For high TDS or a salty taste you need RO.
Size by peak flow: 1,000 LPH covers one shower and a tap at once, 2,000 LPH two or three bathrooms with some overlap, 3,000 LPH a larger home, and 6,000 to 9,000 LPH apartment blocks and businesses. Your hardness then decides how often it regenerates.
If your softener needs regenerating about once a week or less, manual is fine. If your water is hard enough to need it every two or three days, automatic saves you from forgetting. Automatic is available from 1,000 to 6,000 LPH.
Each regeneration uses 4 kg of common salt on the 1,000 LPH model and up to 30 kg on the 9,000 LPH model. How often it regenerates depends on your hardness and use; the running-cost calculator on this page gives a monthly estimate.
Only a little, and iron fouls the resin. Where water stains orange, fit an iron remover before the softener.
Good resin typically lasts three to five years, less if iron or chlorine reaches it. When it stops softening after a proper regeneration, we replace the resin and keep the vessel.
No. An oversized unit costs more and can sit too long between regenerations. Size it to your measured hardness and real peak flow.
You get two lab reports: a pre-treatment report before we recommend anything and a post-treatment report after installation. Both, worth ₹2,000, are included in the price of your system. You pay ₹1,000 when we take the first sample, and it is adjusted when you order. For example, on a ₹65,000 system you pay the remaining ₹64,000.
A lab report tells you how hard your water is, and which softener fits.
