Water Purifier Installation: Charges, Requirements & Checklist

Installation is usually free when bundled with a new purchase from a mainstream brand, and ₹500-₹1,200 as a standalone service. Under-sink and direct-piping installations cost more because they are genuinely plumbing work rather than a wall bracket.

The part worth your attention is not the charge — it is the handover. A rushed installation that skips the TDS baseline, leaves the reject line running to a drain you cannot access, or sets the TDS controller at minimum will cost you money and water for years.

Indicative charges

Installation type	Indicative charge	Typical time
Wall-mount RO (bundled with purchase)	Usually free	45-90 minutes
Wall-mount RO (standalone)	₹500 - ₹1,200	45-90 minutes
Counter-top / table-top	₹300 - ₹700	30-45 minutes
Under-sink with separate faucet	₹1,200 - ₹2,500	2-3 hours
Direct-piping / tankless	₹1,500 - ₹3,000	2-4 hours
Relocation of existing unit	₹500 - ₹1,500	1-2 hours

These are indicative market ranges across India, useful for sanity-checking a quote. Actual charges vary by city, brand and whether parts are genuine or third-party. Franchisee pricing for the same service differs meaningfully between cities — always get the quote in writing before work starts.

What your site needs before the technician arrives

An earthed power socket within roughly 1.5 m of the mounting position.
A water inlet point — usually a tee-off from the kitchen tap line — with a shut-off valve.
A drain path for reject water, or a bucket position if you intend to reuse it.
Adequate wall space and a wall that will take fixings. Measure your chosen unit's dimensions against the actual gap, including clearance to open filter housings.
For under-sink: clear cabinet space of roughly 40 x 25 x 45 cm plus withdrawal clearance, and a power point inside or near the cabinet.
Minimum input water pressure of around 5 psi. Low-pressure homes may need a booster pump.

Handover checklist — do not let the technician leave without this

Input TDS and output TDS measured in front of you and written on the installation slip.
TDS controller setting explained, with output confirmed in the 60-120 ppm range (adjust if below 40).
Reject line route shown, and a bucket or drum arranged if you plan to reuse the water.
All filter housings checked for leaks with the system running under pressure.
Filter-change due dates written down — put them in your phone calendar, do not rely on indicator lights.
Warranty card filled in with model, serial number and installation date; service contact number noted.
A demonstration of how to shut the unit off at the inlet valve in case of a leak.

Tip

Ask the technician to run the purifier and fill the tank fully before he leaves, then check every joint. Leaks almost always appear on the first full pressurisation cycle, not during a quick dry check.

Frequently asked questions

What are water purifier installation charges in India?

Installation is usually free when bundled with a new purchase from a mainstream brand. As a standalone service, expect ₹500-₹1,200 for a wall-mounted RO, ₹300-₹700 for a counter-top unit, and ₹1,200-₹2,500 for an under-sink installation with a separate faucet, which is genuine plumbing work.

What do I need to prepare for water purifier installation?

An earthed power socket within about 1.5 m, a water inlet tee-off with a shut-off valve, a drain path for reject water, and adequate wall space including clearance to open filter housings. For under-sink units you also need roughly 40 x 25 x 45 cm of clear cabinet space plus withdrawal clearance and a nearby power point. Input pressure below about 5 psi may require a booster pump.

Can I install a water purifier myself?

Counter-top and gravity units, yes — they need no permanent fitting. A wall-mounted RO is possible if you are comfortable with drilling and plumbing tees, but self-installation commonly voids warranty and incorrectly seated membranes or crushed o-rings can produce water that appears purified while bypassing the membrane. Since installation is usually free with purchase, there is little reason to do it yourself.
