At Marks Supply and TML Supply Ontario we believe that knowledge is just as important as the products we provide. Investing in training means investing in our team, our customers, and the quality of every project.

Today, we partnered with Dave Holdorf for a full day of hydronic training, expanding our knowledge and sharpening our expertise so we can continue delivering the best support and solutions.

Stay tuned for highlights from today’s session, more photos, and key takeaways. We’re excited to share what we learned!

If you’ve ever pulled apart a water heater and found pipes caked in white scale, you know the story…

👉 Scale buildup = reduced efficiency, shorter life, and more service calls.
👉 Descaling = extra time, extra cost, and not always a fun job.

That’s why the new AO Smith Adapt™ SC Tankless Water Heater is such a game changer. With X3™ Scale Prevention Technology, it:
✅ Stops scale before it starts
✅ Lasts up to 3X longer than standard tankless units
✅ Needs no regular descaling
✅ Comes with a 15-year heat exchanger warranty

Less callbacks for you. More value for your customers. Everybody wins.

And here’s the best part: AO Smith Adapt™ SC is available exclusively at Marks Supply.

At Marks, we don’t just stock product — we support plumbers with:
✔️ Expert product advice
✔️ Hands-on training
✔️ 24/7 online ordering at markssupply.ca
✔️ A strong network of branches across Ontario

The right product + the right partner = jobs done right. 👊

Toronto is a city that sets high standards — and so does American Standard.

We’re excited to share this rooftop installation in Downtown Toronto, completed by our trusted partner Fine Line Energy. Their team continues to raise the bar in delivering professional, energy-efficient HVAC solutions that keep buildings performing at their best.

The spotlight here is on the American Standard rooftop unit — engineered for durability, energy efficiency, and long-lasting performance. For contractors, building owners, and property managers, it’s the kind of reliability you can count on year after year.
