What is Reverse Osmosis Technology?

Reverse Osmosis is a water purification process that removes contaminants by forcing water through a semi-permeable membrane under high pressure. This membrane has tiny pores (approximately 0.0001 microns) that allow only water molecules to pass through while blocking dissolved salts, heavy metals, bacteria, viruses, and other impurities.

Key Components of an RO Water Purifier

Understanding these components will help you during installation and maintenance:

Pre-Filter System

• Sediment Filter: Removes large particles like sand, dust, and rust

• Carbon Filter: Eliminates chlorine, bad odor, and organic compounds

• Purpose: Protects the RO membrane from damage and extends its lifespan

RO Membrane

• The heart of the purification system

• Removes dissolved solids, heavy metals, and microscopic contaminants

• Typical lifespan: 2-3 years with proper maintenance

• Efficiency depends on proper water pressure (40-60 PSI)

Storage Tank

• Stores purified water (typically 7-12 liters capacity)

• Made of food-grade plastic or stainless steel

• Maintains water pressure for dispensing

Post-Filter System

• Activated Carbon Filter: Improves taste and removes residual odors

• Mineralizer (optional): Adds essential minerals back to water

• UV Filter (in some models): Provides additional disinfection

Electric Pump

• Required when input water pressure is below 40 PSI

• Most Bangalore homes need this due to low water pressure

• Consumes 25-50 watts of electricity

Solenoid Valve

• Automatically stops water flow when tank is full

• Prevents water wastage

• Protects system from damage

Why Bangalore Needs RO Water Purifiers

Bangalore's water supply comes from multiple sources including Cauvery river, borewells, and lakes. Here's why RO systems are crucial:

High TDS Levels: Many Bangalore localities report TDS levels between 500-1500 ppm. The BIS (Bureau of Indian Standards) recommends water with TDS below 500 ppm for drinking.

Borewell Water Concerns: Areas relying on borewell water often face issues with:

• Excessive hardness (calcium and magnesium)

• Nitrate contamination

• Heavy metal presence (arsenic, lead)

• Bacterial contamination

Municipal Water Treatment Limitations: While BWSSB (Bangalore Water Supply and Sewerage Board) treats water, distribution through aging pipelines can reintroduce contamination.

Seasonal Variations: Water quality in Bangalore fluctuates significantly between monsoon and summer seasons, requiring year-round purification.

Pre-Installation Planning: Critical Steps Before Setup

Proper planning prevents poor performance. Here's your pre-installation checklist:

Step	Key Checks	Details	Why It Matters
Step 1: Water Quality Testing	• TDS level • pH level • Hardness • Heavy metals • Bacterial contamination • Nitrate & fluoride	Where to Test in Bangalore: • BWSSB Labs • Metropolis / Thyrocare • RO service providers (often free) • Home TDS kits (₹300–₹500)	Water quality decides RO type. High TDS needs different configuration than bacterial contamination.
Step 2: Selecting the Right Location	• Near kitchen sink • Close to water line • Space: 18" W × 24" H • 6–12" clearance • Wall mounting / under-sink	Location Requirements: • No direct sunlight • Away from heat sources • Above ground level • Near power outlet • Strong wall (supports 15–20 kg) Optional: Install in utility room via additional plumbing	Ensures easy access, long filter life, safe operation, and convenient maintenance.
Step 3: Water Pressure Check	Required: 40–60 PSI	How to Check: • Pressure gauge • Water flow observation • Installer measurement Bangalore Conditions: • Ground floor: Usually OK • Upper floors: Low pressure • Borewell homes: Need booster pump	RO requires stable pressure. Low pressure reduces output; booster pump may be required.
Step 4: Adequate Drainage	• Drain pipe access • Gravity flow slope • No sewage contact	Reject Water Usage: • Gardening • Floor cleaning • Car washing • Toilet flush Waste Ratio: Old RO: 3–4L waste per 1L purified Modern RO: 1:1 or 2:1	Prevents backflow issues and enables eco-friendly reuse of reject water.
Step 5: Electrical Requirements	• 220–240V AC • 5A socket • 25–50W usage • MCB protection	Bangalore Notes: • Voltage fluctuations common • Use stabilizer for premium RO • Choose auto-restart models • Battery backup recommended in power-cut areas	Ensures safe, uninterrupted RO performance and protects internal components.

Take photos of unboxing.
Phase 2: Wall Mounting or Floor Setup	Secure the unit in a stable position for optimal performance.	Wall-Mounted: - Mark points with level tool (12" from ceiling, 6" from sides) - Drill for wall type (use rawl plugs) - Secure brackets, hang unit, test stability Under-Sink: Clean/dry cabinet, adequate space, away from leaks Counter-Top: Level surface, access to tank, away from edges	Common in apartments; check wall type (concrete/brick) for drilling.	Use professional help for drilling if unsure. Ensure ventilation to prevent overheating.
Phase 3: Water Inlet Connection	Connect to main water line precisely to avoid leaks.	- Identify cold water line, shut off supply - Install adapter (push-fit/threaded, Teflon tape 3-5 wraps) - Connect 1/4" food-grade tubing (cut straight, secure fittings) - Add inlet ball valve	- Borewell: Add sediment filter - Corporation water: Check existing filter - Hard water: Pre-softener - Low pressure: Booster pump	Turn water on slowly post-connection. Test for leaks at each joint.
Phase 4: Storage Tank Installation	Prepare and connect tank for purified water storage.	- Check pre-pressurization (5-7 PSI) - Position stably below unit - Connect valve with Teflon tape (don't overtighten) - Use 3/8" tubing to RO output	Space constraints in small kitchens; place in utility area if needed.	Access air valve easily for future checks. Sanitize tank before first use.
Phase 5: Drain Line Connection	Set up reject water drainage to prevent backups.	Options: - Sink drain saddle (drill/seal) - Separate line (downward slope, no kinks) - Collection bucket with overflow	- Society rules for drainage - Collect for gardening/cleaning to save water	Minimize tubing length; install air gap. Aim for 1:1 waste ratio with efficient models.
Phase 6: Faucet Installation	Install dedicated faucet for easy purified water access.	- Choose location (sink edge/counter) - Drill hole (1/2" bit, slowly for granite) - Mount with gaskets/nut - Connect 1/4" tubing from tank	- Granite common: Pro drilling advised - Stainless sinks: DIY-friendly - Modular kitchens: Use pre-drilled	Ensure ergonomic height. Test swivel and flow after install.
Phase 7: Electrical Connections	Power up safely for pump/UV functionality.	- Match voltage (220-240V, 25-50W) - Use dedicated/grounded socket - Connect UV (check indicator) - Wire auto-shutoff solenoid	- Fluctuations: Add surge protector - Power cuts: Battery backup option	Avoid extensions; verify earthing. Test all indicators before full run.
Phase 8: Tubing and Connection Finalization	Route and secure all tubes, then test for leaks.	- Organize by color (red/blue=inlet, yellow=reject, etc.) - Secure with ties, avoid bends - Leak test: Run 10 mins, check drips - Adjust lengths/valves	Tube routing in tight Indian kitchens; label for service techs.	Run flush cycle first (discard initial water). Schedule pro check post-install.
