⭐ Why Choose Us

Why Montreal Homeowners Trust Our Water Filtration & Purification Installation

Montreal’s tap water is treated to meet safety standards, but that doesn’t mean it always tastes or feels the way you want it to. Chlorine taste, mineral buildup, sediment, and aging plumbing in older buildings can all affect the water coming out of your faucet. We design and install systems that address these issues at the source β€” from a single under-sink unit to a whole-house solution β€” so every tap in your home delivers clean, great-tasting water.

As licensed plumbers, we don’t just sell equipment. Every Water Filtration Installation Montreal job includes the full installation: connecting to your cold water supply, setting up drain lines where needed, mounting dedicated faucets, and pressure-testing the finished system to make sure everything runs safely and efficiently from day one.

5 Water Filtration & Purification Services We Provide in Montreal

There is no single best water treatment system β€” the right choice depends on what’s actually in your water, how many taps you want treated, available space, and budget. Here is how the five main options compare before your Water Filtration Installation Montreal appointment.

🚰

1. Under-Sink Water Filtration

A compact system installed directly beneath your kitchen sink, ideal for households that want cleaner drinking and cooking water without altering their whole plumbing setup. Includes a dedicated faucet and a clean connection to your existing cold water line.

πŸ”¬

2. Reverse Osmosis (RO) Systems

RO systems use a semi-permeable membrane to remove a broader range of contaminants β€” including sediment, chlorine byproducts, and dissolved solids β€” than standard carbon filtration alone. We install the full setup: pre-filter and post-filter stages, RO membrane, storage tank, drain saddle, and a dedicated faucet.

🏠

3. Whole-House Filtration

Installed at the point where water enters your home, a whole-house system filters water for every fixture β€” kitchen, bathrooms, laundry, and more β€” rather than a single tap. This is the right fit for households concerned about sediment, hard water, or chlorine odor throughout the property.

πŸ”§

4. Water Filter & Purifier Installation

Already purchased a system, or know which one you want? We handle professional installation for most residential water filters and purifiers, including proper connection to your plumbing, leak testing, and system setup.

πŸ”„

5. Maintenance & Filter Replacement

Filters and membranes lose effectiveness over time. We offer maintenance visits and filter replacement service to keep your system performing the way it did on day one β€” on a schedule matched to your usage.

πŸ“ Choosing Guide

Under-Sink, RO, or Whole-House? Choosing the Right System for Your Montreal Home

An under-treated system leaves you with the same taste and odor you were trying to fix. An oversized whole-house setup adds cost and maintenance you may not need. Getting this choice right is the most important decision in any Water Filtration Installation Montreal project β€” and it is something we assess rather than guess at.

If your only concern is drinking and cooking water, an under-sink or RO system at the kitchen tap is usually sufficient. If you’re dealing with sediment, hard water, or chlorine odor throughout the home, a whole-house system treats water at every fixture instead of one.

πŸ“ Key Factors We Assess Before Recommending a System

βœ“What you actually want to fix β€” chlorine taste, odor, sediment, scale, or dissolved solids
βœ“How many taps need treated water β€” kitchen only, or every fixture in the home
βœ“Your building’s age and plumbing condition, common in older Montreal properties
βœ“Incoming water pressure and whether the equipment can run correctly on it
βœ“Available space under the sink, in the utility room, or at the main water entry point
βœ“Whether a drain connection and dedicated faucet are required for the unit
βœ“Ongoing filter and membrane replacement cost over the life of the system
πŸ’‘ Filtration generally removes physical particles like sediment and reduces chlorine taste and odor using carbon media. Purification, such as reverse osmosis, targets a wider range of contaminants at a finer level β€” including many dissolved substances that basic filtration doesn’t fully address.
πŸ”„ Our Process

Our Water Filtration Installation Process β€” Step by Step

Every Water Filtration Installation Montreal we complete follows a systematic, code-compliant process. Most under-sink and RO installations are finished in a single visit β€” usually within a few hours.

1

Assessment

We review your water concerns, check your plumbing, pressure, and available space, and confirm what the system you’re considering will actually require.

2

Recommendation

You receive a clear comparison of suitable options β€” under-sink, reverse osmosis, or whole-house β€” with transparent, itemized pricing before any work begins.

3

Cold Water Connection

We tap into your cold water supply line with correct, code-compliant fittings and a shut-off valve so the unit can be isolated for future servicing.

4

Drain Line & Faucet

Where required, we install the drain saddle or drain connection and mount your dedicated filtered-water faucet cleanly at the sink.

5

System Setup & Flush

Filter stages, membrane, and storage tank are installed in the correct order, then the system is flushed and charged to the manufacturer’s specification.

6

Pressure Test & Walkthrough

We pressure-test for leaks, confirm flow at the tap, then walk you through filter changes and basic maintenance before we leave your property.

πŸ”„ Maintenance

Maintenance, Filter Replacement, and Long-Term Performance

A filtration or purification system only performs as well as the media inside it. Cartridges clog, carbon becomes saturated, and RO membranes lose rejection rate over time β€” usually gradually enough that you don’t notice until taste, odor, or flow drops off. We offer maintenance visits and filter replacement service to keep your system performing the way it did on day one.

Replacement intervals depend on the filter type, your water usage, and household size, but most residential filters need replacement every few months to once a year. Rather than applying a generic schedule, we recommend one based on your specific system and usage during installation or a maintenance visit.

πŸ’‘ What a Maintenance Visit Covers

βœ“Sediment and carbon pre-filter replacement on under-sink and whole-house systems
βœ“RO membrane inspection and replacement when performance has dropped
βœ“Post-filter and polishing stage replacement before the dedicated faucet
βœ“Storage tank pressure check and system sanitization where applicable
βœ“Fitting, tubing, and drain saddle inspection for leaks or wear
βœ“Flow and pressure check at the tap, plus a replacement schedule for the year ahead

πŸ›‘οΈ Safety First

Why Work With a Licensed Plumber for Filtration & Purification Installation

A water filtration or reverse osmosis system involves real plumbing work: tapping into a cold water supply line, sometimes adding a drain connection, and making sure water pressure and fittings are correct for the equipment. A licensed plumber ensures the installation is done to code, leak-free, and won’t create problems with your home’s existing plumbing down the line β€” something a generic handyman installation can’t always guarantee.

🚿

Correct Cold Water Supply Tap

The supply connection is made with proper fittings and an accessible shut-off valve β€” not a temporary saddle valve that fails and drips months later.

πŸ•³οΈ

Proper Drain Connection

RO wastewater lines are connected with a correctly positioned drain saddle above the trap, preventing back-siphoning and drain odor at the sink.

πŸ“Š

Pressure Verified for the Equipment

We confirm your incoming pressure is within the manufacturer’s range so the system produces properly and fittings aren’t stressed over time.

πŸ”—

Code-Compliant, Leak-Tested Work

All water and drain connections are made to current Quebec plumbing code standards β€” inspectable and covered by our labor guarantee.

❓ FAQ

Frequently Asked Questions β€” Water Filtration Installation Montreal

How is a water filtration system installed?

Installation typically involves connecting the unit to your home’s cold water supply, running any necessary drain lines, mounting a dedicated faucet if required, and pressure-testing the system to confirm there are no leaks before it’s put into regular use.

Can a plumber install a reverse osmosis system?

Yes. A reverse osmosis installation includes connecting pre- and post-filter stages, the RO membrane, a storage tank, a drain saddle, and a separate faucet β€” work that falls squarely within licensed plumbing.

Does an RO system need its own faucet and drain connection?

Most residential RO systems use a dedicated faucet for filtered water and a drain saddle connection to remove wastewater created during filtration. Both are set up as part of a standard installation.

What’s the difference between water filtration and water purification?

Filtration generally removes physical particles like sediment and reduces chlorine taste and odor using carbon media. Purification, such as reverse osmosis, targets a wider range of contaminants at a finer level, including many dissolved substances that basic filtration doesn’t fully address.

Do I need a whole-house system or is under-sink enough?

If your only concern is drinking and cooking water, an under-sink or RO system at the kitchen tap is usually sufficient. If you’re dealing with sediment, hard water, or odor throughout the home, a whole-house system treats water at every fixture.

How often should a water filter be replaced?

This depends on the filter type, water usage, and household size, but most residential filters need replacement every few months to once a year. We can recommend a schedule based on your specific system during installation or a maintenance visit.

Why does my Montreal tap water sometimes taste or smell like chlorine?

Municipal water is treated with chlorine to keep it safe during distribution, which can leave a noticeable taste or odor at the tap. A carbon-based filtration system is typically effective at reducing this.
