Water Treatment Calgary — Soft, Clean, Safe Water
Calgary's hard water affects your pipes, skin, and appliances. R N T Plumbing and Heating installs water softeners and filtration systems across Calgary — for softer, cleaner, better-tasting water throughout your home.
What to Expect
Calgary's water is notoriously hard, which leads to scale buildup in pipes and appliances, dry skin and hair, and spots on fixtures. R N T Plumbing and Heating installs water softeners and whole-home filtration systems tailored to your water.
We start with a free water test, then recommend the right softener or filtration system for your home and budget. Every installation is done to code and backed by our 5-year warranty on labour and parts.
Calgary draws its water from the Bow and Elbow rivers, and while it's treated and safe to drink, it's also hard — loaded with dissolved minerals that leave scale on everything they touch. Over time that scale narrows pipes, coats heating elements, and shortens the life of appliances like dishwashers and washing machines.
The right system depends on what's actually in your water. A free in-home test tells us whether your main concern is hardness, chlorine taste, sediment, or something else — and we recommend only the equipment that addresses your real water, not a one-size-fits-all package.

"I manage several properties in Calgary. I have used several different plumbing companies over the years and by far R N T Plumbing has been the best Most recently another company came in because 3 out of 4 sinks had no water. They said all 3 faucets had to be replaced. I decided to get a second opinion from R N T and sure enough no need for replacement, just a part. Saved me over $2000. Such a great team, friendly, very responsive and they want to help, not just make money. Thank you R N T."

He was honest about what actually needed to be fixed, didn't try to upsell me on unnecessary parts, and he was incredibly respectful of my home.

"Bobby showed up on time and inspected my hot water heater. I thought I was going to need a replacement that was going to cost me thousands of dollars, and he ended up saving that for me! He also installed a set of shower taps and had to run some new lines. He was professional and courteous and when I need his help again, I know he will be there, on time, professional and clean up after himself."
