How We Install a Reverse Osmosis Water Filtration System

1

First, we test your household’s water supply and review your family’s water usage to recommend a reverse osmosis drinking water system that suits your needs. We’ll also determine the best system size and storage tank capacity to support your day-to-day habits.

2

We prep the installation zone—typically under the kitchen sink—by clearing enough space and ensuring protective coverings are in place. Then we connect the system to your cold water line using secure, high-grade fittings to prevent leaks or performance issues.

3

A small drinking water tap is installed on your sink or counter. We drill with care to protect surrounding finishes, and we run a dedicated drain line to properly channel away filtered waste water.

4

Once installation is complete, we flush out the system to eliminate any factory residue and perform a pressure check. We test the new reverse osmosis water filtration system for proper flow and clarity and make sure all lines are sealed tight.

Before leaving, our techs show you exactly how the system works—how to use it, when to change filters, and how to keep your reverse osmosis system in top shape with simple maintenance steps.

FAQs About Reverse Osmosis Water Filter Systems

What is a Reverse Osmosis Water Filter?

A reverse osmosis water filter is an advanced purification system that targets microscopic contaminants in your water supply. Unlike standard filters, a reverse osmosis water filtration system uses a semi-permeable membrane to separate water molecules from unwanted particles. These systems typically include three to five stages: pre-filters for sediment and chlorine, the main membrane for intensive filtration, and a post-filter to ensure great taste. The result? Crisp, clear water free from heavy metals, volatile chemicals, and invisible contaminants that may affect your health or your home’s plumbing.

How Does a Reverse Osmosis Water Filter Work?

A reverse osmosis water filtration system works through a step-by-step process that removes impurities from tap water:

  1. Water first passes through a sediment pre-filter to remove dirt, rust, and suspended particles.
  2. It then flows through a carbon block filter to eliminate chlorine, odours, and volatile organic compounds (VOCs) that can harm the RO membrane.
  3. In the core stage, water is pushed through the reverse osmosis membrane, which blocks nearly all remaining contaminants—including heavy metals, nitrates, and bacteria. Purified water is stored in a pressure tank until you’re ready to use it.
  4. When the faucet is turned on, the water flows through a final polishing filter to enhance taste and freshness before it reaches your cup.

This thorough process ensures your reverse osmosis drinking water system delivers unmatched purity and safety in every sip.

What Size of Reverse Osmosis Water Filter Do I Need?

Your ideal system size depends on how much filtered water your household uses each day. Homes with 1–3 people typically need a 50-gallon-per-day system, which handles most drinking and cooking needs. Families of 4–6 often benefit from a system rated for 75–100 gallons daily, while larger homes or properties with high water usage may require 150+ gallon units or multi-tap configurations. Our technicians will assess your water needs during a consultation and recommend a reverse osmosis water filter that fits your usage, kitchen space, and budget.
