A Clear Guide to RO Installation Charges in Kolkata | Transparent Pricing

You Bought a New Water Purifier. Now, What About the RO Installation Charges?

Congratulations on purchasing a new Reverse Osmosis (RO) water purifier! Whether you bought a sleek new Kent Grand from an online sale, an Aquaguard from a local Croma store, or a heavy-duty assembled unit for Kolkata’s hard water, you have taken a vital step toward protecting your family’s health.

But now, the cardboard box is sitting in your kitchen, and you are faced with the next crucial step: getting it up and running. This brings us to the most common question new owners ask: What are reasonable RO installation charges in Kolkata?

Many people assume installation should be free or dirt cheap. While some brands offer “free installation,” there are often hidden conditions. If you have purchased online, or if you are moving houses and need re-installation, you need a reliable third-party technician.

At ro-service-near-me.com, we believe in absolute transparency. In this guide, we will break down everything that determines RO installation charges, why you shouldn’t cut corners on this step, and what you can expect to pay in Kolkata.

Why Professional Installation is Worth the Cost

Before we discuss the exact RO installation charges, it is important to understand why this isn’t a DIY job. We have seen many cases where homeowners tried to save a few hundred rupees by installing the unit themselves, only to face bigger problems later.

A professional RO installation ensures:

Warranty Protection: Many manufacturers will void your warranty if the unit isn’t installed by a certified or experienced technician.
Leak Prevention: Incorrectly connecting the inlet valve or drain pipe can lead to kitchen flooding and water damage.
Optimum Pressure: A technician checks the input water pressure. If it’s too low, your RO membrane won’t work; if it’s too high, housings might crack. A professional knows if you need a pressure-reducing valve.
TDS Adjustment: After installation, the purified water’s TDS needs to be checked and adjusted to ensure essential minerals are retained.

When you pay professional RO installation charges, you are paying for peace of mind, not just drilling two holes in the wall.

Factors That Influence RO Installation Charges

When you call around Kolkata asking for a price quote, you might get different answers. Why isn’t there a single fixed rate?

The truth is, RO installation charges vary because every kitchen setup is different. Here are the main factors that influence the final cost:

1. The Type of Unit

Standard Wall-Mounted RO: These are the most common and straightforward to install.
Under-Sink / Undercounter RO: These units are complex. They require cutting into the countertop for the faucet and working in tight spaces under the sink. Naturally, the RO installation charges for these units are higher due to the time and labor involved.

2. The Installation Site Readiness

Does your kitchen already have an existing water inlet point and an electrical socket near the desired spot?

Yes: The installation will be quick, and charges will be basic.
No: If the technician needs to draw long pipes from a distant tap, or if plumbing modifications are required to create an inlet source, labor charges will increase.

3. Additional Parts Required

Most new RO boxes come with a basic installation kit (a few feet of pipe, a diverter valve, and screws). However, Kolkata kitchens often require extras:

Extra Tubing: If the water source is far away.
Pre-Filter Housing: Highly recommended in Kolkata due to high mud content in tap water. If your unit didn’t come with one, buying and installing an external pre-filter adds to the cost.
Pressure Reducing Valve (PRV): Essential for high-rise buildings where water pressure is immense.

When quoted RO installation charges, always ask if basic parts are included.

Standard RO Installation Charges in Kolkata (Typical Price Ranges)

At ro-service-near-me.com, we keep our pricing competitive and transparent. While final prices depend on the site visit, here are the typical market rates for RO installation charges in Kolkata.

Please note: These prices are indicative of service charges. Cost of spare parts, if needed, is extra.

1. New Unit Installation (Basic Wall Mount)

This involves unboxing, mounting the unit, connecting the inlet and drain pipes, and a demo run.

Typical Charges: ₹400 – ₹600

2. Re-installation (Moving Houses)

This is a two-step process: safely uninstalling the unit from your old location (ensuring no water spills or membrane damage) and installing it at the new location.

Uninstallation Only: ₹250 – ₹350
Complete Shifting Package (Uninstall + Reinstall): ₹700 – ₹900

3. Under-Sink RO Installation

As mentioned, this is labor-intensive and requires specialized tools for countertop drilling.

Typical Charges: ₹1000 – ₹1500

Beware of “Too Good To Be True” Low Prices

You might find a local mechanic offering to install your expensive machine for ₹200. Be cautious. Often, extremely low RO installation charges are a bait-and-switch tactic.

Once the technician arrives, they might claim your inlet valve is broken and force you to buy an overpriced replacement, or they might do a rushed, sloppy job that leads to leaks a week later.

Cheap installation often ends up being the most expensive option in the long run.
