A homeowner in Surrey called us a while back — not for an installation, but for a second opinion. Another company had told her that her two-year-old Navien tankless water heater needed to be replaced. It was failing: poor hot water pressure, error codes, inconsistent heating. She'd paid over $6,000 for it and couldn't believe it was already done.
When our technician opened it up, the heat exchanger was scaled solid. White, chalky mineral deposits had completely clogged the unit. The original installer had never mentioned water quality. The manufacturer's warranty? Voided — water quality damage isn't covered.
That call stuck with us. A perfectly good water heater, destroyed not by a mechanical failure but by what was flowing through it every day. We started paying closer attention to water quality on every job after that — and what we find in homes across Surrey, Langley, and the Lower Mainland surprises most homeowners.
Metro Vancouver's source water — from the Capilano, Seymour, and Coquitlam mountain reservoirs — is genuinely excellent. But by the time it reaches your tap, it's been treated with chemicals that are doing real damage inside your home.
What's Actually in Your Metro Vancouver Tap Water
Metro Vancouver is required by law to deliver microbiologically safe water to your tap. To do that, they use chlorine and chloramines as disinfectants — added at the treatment plant and again at secondary disinfection stations throughout the distribution network. This is standard practice and it works: it kills bacteria and keeps the water safe from the reservoir to your home.
But here's what most homeowners don't know.
Chlorine and Chloramines
Chlorine is a powerful oxidizer. It kills bacteria without distinguishing between the bad organisms in your water and the good organisms in your body. Residents across Surrey, South Surrey, and Burnaby have complained about strong chlorine smells and tastes in their tap water — particularly in late 2025 when a geosmin event caused widespread complaints about mouldy-smelling water across Metro Vancouver.
In your shower, the problem is worse. Hot water opens your pores and vaporizes chlorine into steam. You absorb more chlorine in a 10-minute hot shower than you would from drinking 8 glasses of the same water. This is why many people with dry skin, eczema, or dull hair find that their symptoms improve dramatically after installing a whole-home filtration system.
Trihalomethanes (THMs) and Haloacetic Acids (HAAs)
When chlorine reacts with organic matter naturally present in water, it creates disinfection byproducts — primarily trihalomethanes (THMs) and haloacetic acids (HAAs). Metro Vancouver's own 2025 Water Quality Annual Report monitors and reports these levels. Studies published in peer-reviewed journals have linked long-term exposure to chlorination byproducts to increased cancer risk. These are not trace amounts — they are present in every glass of tap water in the Lower Mainland.
Scale-Forming Minerals
Water hardness varies significantly across the region. White Rock sits at 5.4–5.9 grains per gallon (GPG) — noticeably hard. Chilliwack runs 2.6–3.9 GPG. Even Metro Vancouver's "soft" water at 0.5–0.7 GPG contains dissolved calcium and magnesium that accumulate inside pipes, water heaters, and appliances over time. In a tankless water heater, this scale builds up on the heat exchanger — exactly what we found in that Surrey home.
Sediment and Turbidity
After heavy rain events — which are frequent in BC — sediment and turbidity levels in the water supply can spike. Older homes with aging pipes may also introduce rust and particulates as water travels from the main to your tap.
What Chlorinated Water Is Doing to Your Home
The damage isn't dramatic — it's slow and invisible. That's what makes it so costly.
Your Tankless Water Heater
Tankless water heaters heat water on demand by passing it through a heat exchanger. Scale accumulates on the heat exchanger surface, reducing efficiency and eventually causing failure. Most manufacturers require annual descaling maintenance and may void the warranty if water quality damage is found. A whole-home filtration system with scale prevention eliminates this problem entirely.
Your Dishwasher and Washing Machine
Scale builds up on heating elements, spray arms, and internal components. Chlorine degrades rubber seals and gaskets. The result: appliances that fail years before they should. Industry data suggests hard water and chlorinated water can reduce appliance lifespan by 30–50%.
Your Pipes and Fixtures
Scale accumulates inside pipes, gradually reducing water pressure. Chlorine accelerates corrosion in older copper and galvanized steel pipes. Fixtures develop white chalky deposits that are difficult to remove and get worse over time.
Your Skin and Hair
Chlorine strips the natural oils from skin and hair. If you've noticed dry skin after showering, hair that feels brittle or dull, or skin conditions that don't respond to treatment, your water may be a contributing factor. Many of our customers report noticeable improvement in skin and hair quality within the first week after installing a whole-home filtration system.
The Solution: HALO 5 Whole-Home Water Filtration & Conditioning
Grove Mechanical installs the HALO 5 — a whole-home water filtration and conditioning system that treats every drop of water entering your home before it reaches any tap, shower, appliance, or pipe. It's the system we now recommend with every tankless water heater installation, and it's the system we install in our own families' homes.
How the HALO 5 Works — 5 Stages
The HALO 5 is installed at your main water line, treating all water entering the home through five sequential stages:
- Stage 1 — Granular Activated Carbon (GAC): Removes chlorine, chloramines, heavy metals, pesticides, volatile organic compounds (VOCs), and disinfection byproducts. Eliminates unpleasant taste and odour.
- Stage 2 — High Activity Carbon (HAC): A second carbon stage that polishes the water, removing any remaining chlorine and producing clean, fresh water with no objectionable taste or odour.
- Stage 3 — Filter-AG Plus: An all-natural media that filters suspended particles down to 5 microns, removing sediment and turbidity.
- Stage 4 — High-Density Garnet: Filters fine particles down to 10–20 microns and provides a stable support bed for the other filtration media.
- Stage 5 — HALO ION Inline Water Conditioner: Uses multi-reversing polarity magnetic fields to alter the molecular structure of dissolved calcium and magnesium, preventing scale from forming on pipes and appliances — and dissolving existing scale over time.

The Best Time to Install: Bundle With Your Tankless Water Heater
The most cost-effective time to install a whole-home water filtration system is at the same time as a new tankless water heater. We're already at your home, we're already working on your main water line, and the installation adds minimal time and disruption. More importantly, the filtration system protects your new tankless water heater from day one — before scale has a chance to accumulate.
We now include a HALO 5 recommendation in every tankless water heater quote we provide. Homeowners who add filtration at the time of installation protect their warranty, extend the life of their appliance, and avoid the conversation we had to have with that Surrey family two years ago.
The HALO 5 is also an excellent addition to any heat pump or HVAC installation. If you're investing $8,000–$15,000 in a new heating and cooling system, protecting your home's water quality is a natural complement to that investment.
What Does a Whole-Home Water Filtration System Cost in Surrey?
The HALO 5 system, professionally installed by Grove Mechanical, typically runs $2,500–$4,000 depending on your home's plumbing configuration and water line access. Installation takes approximately 2–4 hours and requires no ongoing maintenance. There are no filter cartridges to replace, no salt to add, and no annual service calls required.
Financing is available through Financeit — including a 0% interest option for the first 6 months — making it easy to add water filtration to any installation project without a large upfront cost.

Frequently Asked Questions
Is Surrey tap water safe to drink?
Surrey tap water meets all Health Canada drinking water guidelines and is treated by Metro Vancouver to remove pathogens. However, it contains chlorine (added for disinfection), chloramines, and disinfection byproducts (THMs) that affect taste, odour, and long-term appliance health. A whole-home filtration system removes these while maintaining water safety.
What does a whole-home water filter remove?
The HALO 5 whole-home system removes chlorine, chloramines, disinfection byproducts (THMs), sediment, heavy metals, and scale-forming minerals. It also conditions water to prevent scale buildup in pipes, water heaters, and appliances — without adding salt like a traditional water softener.
How much does a whole-home water filtration system cost in Surrey?
A HALO 5 whole-home filtration system installed by Grove Mechanical typically costs $3,000–$4,500 including installation. The system requires minimal maintenance (filter replacement every 3–5 years) and pays for itself through extended appliance life and reduced energy costs from scale-free heat exchangers.
Does a water filter affect water pressure?
A properly sized whole-home filter has minimal impact on water pressure — typically less than 5 PSI reduction. The HALO 5 is designed for residential flow rates and will not noticeably affect your shower pressure or appliance performance.
Can I install a water filter myself?
Whole-home water filtration systems require connection to your main water supply line and should be installed by a licensed plumber or mechanical contractor. Improper installation can void the warranty and create leak risks. Grove Mechanical handles installation as part of every HALO 5 purchase.
