Answers for Scale-O combo packs: protecting two tanks, salt-free water softener plans, install tips and how to choose Mini, Semi or Centi sizes.
Chat on WhatsApp
What is Scale-O and how does it work?
Scale-O is a salt-free water softener for Indian homes with overhead tanks. Place the compact unit inside your tank. As water flows through the home, it conditions minerals and helps reduce hard-water scale on pipes, fittings and household appliances, without salt, electricity or plumbing changes.
Is Scale-O a salt-free water softener?
Yes. Scale-O is salt-free, with no salt bags, no refill hassle and no regeneration waste. Compare salt-free vs salt-based water softeners for Indian homes, or see water softener price and plans.
Does Scale-O waste water like salt-based softeners?
No. Scale-O does not backwash or discharge water during regeneration. You get scale protection without the water wastage common in many salt-based systems. Read more in salt-free vs salt-based water softeners.
How does the Scale-O trial / guarantee work?
Scale-O offers a 7-day risk-free trial so you can try salt-free hard-water protection at home. Guarantee activation is confirmed with your invoice. Chat on WhatsApp from this page if you need help choosing a tank size.
Does a water softener reduce hair fall from hard water?
Hard water hair fall in India is often breakage from mineral film, not medical shedding. A salt-free water softener in the overhead tank can help hair feel less dry. Scale-O does not claim to stop balding. See hard water hair fall guide.
Can I install a water softener in an overhead tank without a plumber?
Yes. Scale-O is a DIY water softener for overhead tanks: open the lid, place the unit inside, close and use water normally. No plumber, drain or electricity. Read the overhead tank water softener guide.
ComboWhat is a Scale-O combo salt-free water softener for two tanks?
Combo packs include sized Scale-O units so you can protect two overhead tanks, useful for duplex homes or separate tank lines. Explore water softener combo plans and the water softener for home collection.
ComboHow do I choose Mini, Semi or Centi sizes inside a combo?
Match each unit to each tank: Mini 500L-750L, Semi 1000L-1500L, Centi 2000L-2500L. Confirm tank capacities before you buy.
ComboDo combo units still install without electricity or salt?
Yes. Each unit is a salt-free, no-electricity softener placed in its tank. No shared salt plant or wiring. Compare technology in salt-free vs salt-based water softeners.
ComboIs a combo better than buying one large salt-based softener?
For homes with two overhead tanks, dedicated tank-level Scale-O units often fit Indian plumbing better than one bulky salt plant. See plans and pricing and overhead tank softener guidance.
