Services
Water Softeners
High-efficiency water softeners prevent mineral buildup in plumbing and appliances. We install CSA-approved systems that reduce hardness minerals, improving soap effectiveness and extending equipment lifespan. Our technicians recommend annual resin replacements for optimal performance in Kitchener-Waterloo's hard water conditions.
Reverse Osmosis Systems
Reverse osmosis systems deliver purified drinking water through multi-stage filtration. We offer 5-stage systems with fridge hookups and low-waste models. Regular filter replacements (every 6-12 months) maintain contaminant removal effectiveness for chlorine, heavy metals, and pharmaceutical residues in municipal water supplies.
Tankless Water Heaters
Tankless water heaters provide continuous hot water while reducing energy consumption. We install condensing models that qualify for efficiency rebates. Professional servicing ensures optimal performance in both residential and commercial settings across the Waterloo region.
Filter Replacements
Regular filter replacements maintain water treatment system effectiveness. We supply standard and premium filters for most RO systems, with annual replacements recommended for carbon/sediment filters and 3-5 year intervals for membranes in typical residential applications.
Chlorine Removal
Chlorine removal systems improve water taste and protect plumbing from corrosion. Our whole-house systems combine catalytic carbon filtration with specialized media to eliminate both chlorine and chloramines, addressing common complaints about dry skin and discolored laundry.

We have had all of our softners installed by Ontario Soft Water over the years in both of our homes. Customer service was top notch. All around great experience with this Team. They also installed a reverse osmosis water system in my father's house. Highly recommend.

I did a LOT of homework comparing softeners before choosing Ontario Soft Water. They offer the best products, at the best price, and their service was top tier. Very impressive. I highly recommend them.

We had Jonathan as our contact / installer. We got a water softener, RO, dechlorinator, and hot water tank installed.
Jonathan answered all of questions (of which we had many), and was very patient with us throughout. He looks to have done a clean and tidy install. We had another contractor in to quote us on a differebt job and even they noticed and complimented the tidiness of the plumbing and work that Jonathan did. We had a similar system put in at our last place and it held up well the almost seven years we were there. Assuming the equipment lasts, we are happy overall and would recommend
