Industrial Mechanical & Process Piping
Installation and repair of grooved (Victaulic), threaded, soldered, and press mechanical piping for domestic water, closed-loop hydronics, and compressed air lines.
Sewer Line Diagnostics & Hydro-Jetting
High-definition CCTV video pipe inspections, electronic line locating, and high-pressure water jetting to clear heavy grease, scale, and industrial line blockages.
Commercial Fixtures & Backwater Valves
Heavy-use commercial flushometers, sensor faucets, commercial mop sinks, thermostatic mixing valves (TMVs), and mainline backwater valve installations.
ONTARIO PLUMBING CODE COMPLIANCE
Engineered Plumbing to Prevent Facility Shutdowns
Commercial plumbing failures halt operations immediately. A failed sewer line forces food service shutdowns, while an unexpected pressure drop from a booster station disrupts upper-floor production or tenant operations.
Stillson Mechanical provides Red Seal 306A licensed plumbers trained in commercial mechanical rooms and industrial code standards. We diagnose hydraulic bottlenecks, test pressure regimes, calculate correct line sizing under the Ontario Building Code (OBC Part 7), and deliver turnkey installations that pass municipal inspections the first time.
