Which Water Treatment System is Right for You?
There’s no one-size-fits-all solution when it comes to water treatment.
Here’s a quick guide to the most common systems we install — and how to know which one might be right for your home:

Carbon Filtration Systems
Ideal for improving the taste, smell, and overall quality of your tap water. These systems remove chlorine, sediment, and other impurities, making them a popular choice for city homes connected to municipal water.
Water Softeners
If you’re dealing with hard water — mineral buildup on fixtures, cloudy dishes, or scale in appliances — a water softener can help. These systems reduce calcium and magnesium levels, protecting your plumbing and making water gentler on your skin and hair.
Reverse Osmosis (RO) Systems
RO systems provide high-level filtration for drinking water, removing a wide range of contaminants including lead, chlorine, and other dissolved solids. Typically installed under the kitchen sink, they’re a great choice for families who want exceptionally clean, great-tasting water for drinking and cooking.
UV Disinfection Systems
If your home relies on a well, or if you’re concerned about bacteria or biological contaminants, a UV system adds an extra layer of protection. These systems use ultraviolet light to neutralize harmful microorganisms, keeping your water safe to drink.
Whole-Home Treatment Systems
Looking for peace of mind throughout your entire home? Whole-home systems combine filtration, softening, and other treatments to deliver clean, conditioned water to every tap. These are ideal for larger homes or properties with specific water quality concerns.
Your Nanaimo Water Treatment Specialist
With decades of plumbing experience, we ensure your system is installed properly and operating at its best. We also offer ongoing maintenance services, including filter replacements and system checks — ideal for homeowners who prefer the work done right by a professional.

RM2024-05-11Trustindex verifies that the original source of the review is Google. I was very impressed with Gerry and the service he provided me. My dishwasher was not draining ( was not plumbed into the kitchen sink as most are). Gerry was able to pinpoint where the piping went into my down stairs ceiling and found the blockage in a p trap behind the drywall. He was organized, professional and his pricing was great. Best part was, he was able to attend the day after I called him. Would highly recommend Derek Ross2024-02-15Trustindex verifies that the original source of the review is Google. We recently got a new gas line brought into our house and Gerry plumbed in everything for a range, hot water, furnace and even an outside BBQ! We were thrilled with his professionalism and work ethic. Cathy Taylor2024-01-15Trustindex verifies that the original source of the review is Google.
