How We Install a Reverse Osmosis Water Filtration System

1

We begin by evaluating your home’s water quality, daily usage, and available space to recommend the most suitable reverse osmosis drinking water system for your household. Based on this assessment, our experts will guide you in choosing the right size and configuration to match your water consumption needs.

Next, our team preps the installation area beneath your sink, ensuring there’s enough room for the unit while protecting nearby cabinetry and plumbing. We carefully connect your reverse osmosis filtration system to the cold water supply using durable, high-grade fittings that safeguard against leaks and pressure issues.

3

We then install a dedicated filtered water faucet on your sink or countertop, using precision drilling to maintain the look of your surfaces. A drain line is also connected to safely dispose of impurities removed by the reverse osmosis system.

Once installed, we thoroughly flush the unit to eliminate any leftover residue from manufacturing. We then inspect for leaks, ensure the system functions properly, and verify that the water meets our quality standards.

Before finishing up, our team will walk you through system use and upkeep. We’ll show you how to change the filters and maintain peak performance for long-term reliability.

FAQS About Reverse Osmosis Water Filter Systems

What is a Reverse Osmosis Water Filter?

A reverse osmosis water filter is a highly effective water purification system that eliminates contaminants at a microscopic level. Unlike standard carbon filters, reverse osmosis systems push water through a semi-permeable membrane with tiny pores that allow only water molecules to pass while trapping harmful impurities. These systems use multiple filtration stages—starting with pre-filters that target sediment and chlorine, followed by the main membrane, and finishing with a post-filter to enhance taste and clarity. The result is clean, safe drinking water, free from common pollutants like lead, arsenic, fluoride, chlorine by-products, pesticides, and many other contaminants that traditional filters often leave behind.

How Does a Reverse Osmosis Water Filter Work?

Reverse osmosis water filters use a step-by-step purification method that begins the moment water flows in from your Oshawa home’s plumbing system:

  • In the first phase, the water passes through pre-filters designed to remove larger particles like sand, rust, sediment, and chlorine, preventing premature wear on the membrane.
  • Then, under pressure, the water moves through the reverse osmosis membrane, where microscopic contaminants are blocked and flushed away, while clean water continues through the system.
  • This purified water is collected in a dedicated storage tank, keeping it available on demand.
  • When you activate your filtered water tap, the water runs through a final carbon filter to eliminate any remaining odour or aftertaste before reaching your glass.

This thorough filtration process removes up to 99% of dissolved solids, metals, bacteria, and other contaminants—delivering exceptional water quality straight from your kitchen tap.

What Size Reverse Osmosis Water Filter Do I Need?

The ideal size of a reverse osmosis water filter for your Oshawa home depends on how many people live there and how much purified water you use daily. For smaller households of 1–3 people, a unit that produces around 50 gallons per day usually covers basic drinking and cooking needs. Mid-sized families of 4–6 often benefit from systems rated at 75–100 gallons per day, while larger homes or households with heavier usage may require a high-capacity reverse osmosis system producing 150 gallons or more per day.

During your consultation, Limcan Certified Heating and Air Conditioning will assess your home’s specific needs and recommend a properly sized system that delivers reliable performance without producing unnecessary waste or overcapacity.
