More Than Just a Drain—It’s a Health & Safety Issue
If you operate a restaurant, café, bakery, or food-service facility in Oakville, you already know that health and hygiene are non-negotiable. But one overlooked area that often leads to costly downtime and failed inspections is your commercial kitchen sink drain system. Beneath the surface, years of grease buildup, corrosion, and poor installation can cause leaks, foul odours, and even structural damage.
At 17 Plumbing & Construction Design Ltd, we recently completed a full drain replacement at a commercial hand-washing station near Lakeshore West, Oakville—and the condition we found wasn’t uncommon.
Why Do Commercial Kitchen Sink Drains Fail?
Commercial sink drains are under constant stress. Unlike residential plumbing, commercial kitchen sinks handle:
-Heavy daily usage from staff washing hands, produce, and equipment
-Grease and food particles, which cause buildup and clogging
-Strong cleaning agents that corrode pipes over time
-Hot water temperature extremes that expand and contract joints
The most common causes of drain failure include:
-Corrosion: Older copper or galvanized steel drains rust and weaken
-Loose joints or seals: Especially around the P-trap and wall connection
-Improper slope or alignment: Which causes standing water and odour buildup
-Cracks or pinhole leaks: These often go unnoticed until water damage appears on floors or walls
In many cases, the first visible signs are rust stains on the concrete floor, a persistent musty smell, or leaks under the sink during peak hours.
Our Recent Project – Lakeshore West, Oakville
Our team was called to inspect a handwashing station at a busy café near Lakeshore West and Kerr Street in Oakville. The staff reported a recurring leak and noticed brown stains on the floor near the wall.
Upon inspection, we found:
-A corroded copper tailpiece
-Multiple amateur solder joints with oxidation
-A loose P-trap assembly leaking at the wall
-Signs of previous silicone patching that failed
-We replaced the full vertical tailpiece, installed a solid brass P-trap, and secured all compression joints with commercial-grade seals. The wall escutcheon was cleaned and tightened, and the entire line was flushed and tested.
-Within two hours, the café’s handwashing station was leak-free, clean, and fully code-compliant.

A: We typically use brass or stainless steel for durability and corrosion resistance—especially in kitchens where sanitation is critical.
Q: How long does the service take?
A: Most replacements are done in under 2 hours. We schedule around your business needs, including evenings or weekends if needed.
