Opening a restaurant, cafe, or retail space in Kamloops means more than finding the right location and menu. The plumbing system must meet commercial-grade requirements enforced by the City of Kamloops, Interior Health Authority, and BC Building Code. Fail an inspection and your opening day gets pushed back by weeks. Our commercial plumbing team has helped dozens of Kamloops businesses open on time and pass every inspection.
The biggest difference between residential and commercial plumbing is volume and load. A restaurant kitchen runs water continuously for ten to fourteen hours a day, discharging hot grease, food particles, and high-temperature wastewater into drains designed for a fraction of that load. Residential drain lines simply cannot handle commercial demand — and inspectors know it. Commercial spaces require larger-diameter drains, dedicated grease separation, and backflow protection that residential systems do not.
A grease interceptor — commonly called a grease trap — is mandatory for any food service operation in Kamloops. Grease traps separate fats, oils, and grease from wastewater before it enters the municipal sewer system. Without one, grease solidifies in city pipes, causing blockages that the municipality charges you to clear. Kamloops requires grease traps sized according to fixture count and menu type. A small cafe with primarily coffee service may need a 20-gallon unit. A full-service restaurant with deep fryers needs 50 gallons or more, often with an outdoor in-ground interceptor.
Grease traps must be installed with proper venting, cleanout access, and a flow control device that limits discharge to the trap's rated capacity. The trap itself needs regular pumping — typically every 30 to 90 days depending on volume. A neglected grease trap overflows into the kitchen, creates foul odors, and fails health inspections. We set up maintenance schedules for our commercial clients so pumping happens automatically before it becomes a problem.
Backflow prevention is another non-negotiable. A backflow preventer stops contaminated water from siphoning back into the municipal supply — a risk anytime commercial equipment creates pressure differences. All commercial properties in Kamloops with food service, irrigation, boiler, or chemical processes must have a certified backflow preventer installed, tested annually, and reported to the city. We are certified to install, test, and file the paperwork for backflow devices across all risk categories.
Drainage design in commercial kitchens is more complex than most owners realize. Floor drains must be strategically placed so the entire kitchen floor slopes toward them — typically 1/4 inch per foot. This prevents standing water, which is a health code violation. Stainless steel floor sinks, trench drains, and hub drains each serve different purposes and must be specified correctly for the kitchen layout. A licensed commercial plumber coordinates this with your general contractor and health inspector.
Water heater sizing is critical for restaurants. A busy kitchen with a three-compartment sink, dishwasher, and hand sinks may need a 100-gallon commercial gas water heater or a tankless bank with sufficient flow rate. Residential tanks fail under this load and will not pass inspection. Commercial units also need temperature control — dishwashers require 60°C minimum for sanitization, but hand sinks must not exceed 49°C for safety. Mixing valves and tempering equipment manage these requirements.
Retail spaces have different requirements but are not exempt from commercial compliance. Any retail space with public restrooms, a lunchroom, or cleaning mop sinks needs plumbing sized for higher use volume than residential standards. Water pressure must remain adequate across all fixtures simultaneously. Drainage must handle peak loads. And if the space includes a sprinkler system, the water supply must be sized for both domestic and fire protection demand.
Permits and inspections for commercial plumbing in Kamloops follow a multi-stage process. The licensed plumber submits plans for review, installs rough plumbing, schedules a rough-in inspection, installs fixtures and equipment, and schedules a final inspection. Interior Health may also inspect for food service compliance. Missing any stage delays occupancy. We coordinate directly with city inspectors and health authorities to keep projects on schedule.
Emergency service is just as important for businesses as for homes. A backed-up floor drain on a Friday night can shut down a restaurant's entire weekend revenue. A failed water heater means no dishwashing and a health closure. Our emergency plumbing team carries commercial-grade equipment and parts, understands the urgency of business downtime, and works to minimize disruption. We have responded to midnight calls at restaurants in downtown, Sahali, and Valleyview — and kept them open.
If you are planning a new commercial space or renovating an existing one in Kamloops, involve a licensed commercial plumber during the design phase — not after construction starts. Early involvement lets us size systems correctly, identify code requirements, coordinate with other trades, and prevent the expensive rework that happens when plumbing is treated as an afterthought. A pre-construction consultation costs nothing and can save you thousands.
