Commercial Plumbing — Restaurants, Retail & Office Buildings
Delex Plumbing provides licensed commercial plumbing services across Mississauga — restaurants, retail spaces, office buildings, and multi-unit residential. Services include 24/7 emergency response, code-compliant commercial installations, grease trap service, gas line connections, and backflow preventer testing — all handled by certified technicians.
Commercial Plumbing Services — Mississauga Businesses
Commercial plumbing operates under higher demand, stricter code requirements, and more immediate cost-of-failure consequences than residential plumbing. A restaurant kitchen that loses its drain at 11 p.m. on a Friday loses the weekend’s revenue. An office building with a broken main shut-off valve cannot be occupied until it is repaired. We understand that commercial plumbing emergencies are business emergencies, and our 24/7 emergency plumbing response treats them accordingly.
Commercial plumbing systems operate at higher pressure, higher flow rate, and on larger pipe diameter than residential systems. A 2-inch commercial kitchen drain handles significantly more volume than a 1.5-inch residential drain, and requires appropriately sized tools and jetter nozzles for effective cleaning. Our commercial plumbing equipment is sized for the job — we do not use residential equipment on commercial systems and then bill for ineffective service.
After-hours commercial plumbing service is critical for restaurants, which operate until 10 p.m. to midnight and cannot afford to close early for a drain service that could be completed during the off-hours window between midnight and 7 a.m. We schedule after-hours commercial service for businesses whose operations require it, providing the same licensed, insured professional service at the same flat-rate pricing regardless of the hour.
Our commercial plumbing services include: emergency repair for all plumbing systems, grease trap installation and maintenance, backflow preventer installation and annual Peel Region testing, commercial drain cleaning and hydro jetting, water heater replacement, and commercial fixture installation and repair.
Restaurant Plumbing — Grease Trap & Kitchen Drain Service
Restaurant kitchen drains carry the highest concentration of grease, food solids, and detergent of any plumbing system. Without a properly maintained grease trap and regular drain cleaning, kitchen drains in food service establishments block completely within 3 to 6 months of installation. Peel Region requires grease traps on all food service establishments. Our drain and sewer team handles grease trap installation and service.
We install in-ground and under-sink grease interceptors, perform Peel Region-compliant maintenance pumping, and provide the required service documentation for inspections. Commercial kitchen drain cleaning by hydro jetting fully removes grease accumulation from the entire drain system — not just the trap — and is the appropriate maintenance frequency for high-volume restaurants.
Commercial Backflow Preventer Testing — Peel Region Compliance
Peel Region requires annual testing of commercial backflow preventer devices by a certified tester. The test verifies that the check valves and differential pressure valve inside the device function correctly. We perform the backflow preventer test, provide the required report, and file it with Peel Region on your behalf.
Commercial properties that do not complete annual backflow testing risk a municipal compliance notice and potential water service interruption. We manage the testing schedule and send proactive reminders to property managers and business owners before the annual testing deadline.
Commercial Drain Cleaning & Emergency Service
Commercial floor drain systems, kitchen drains, and washroom drains in office buildings require periodic cleaning to maintain compliance with municipal pre-treatment requirements and to prevent business-disrupting blockages. We provide scheduled commercial drain cleaning contracts — monthly, quarterly, or annual depending on the facility type — and emergency commercial drain service for acute blockages.
Commercial hydro jetting clears grease, food solids, and scale from 4-inch to 12-inch commercial drain lines. For large-diameter storm and sanitary lines in multi-unit residential buildings, we use high-capacity jetting equipment capable of clearing roots and debris from 8 to 12 inch pipes.
Office Building & Retail Plumbing
Office buildings and retail spaces have different plumbing demands than restaurants but equally urgent failure consequences. A burst supply line in an office building above occupied space causes immediate tenant displacement and significant water damage to multiple floors. A failed washroom in a retail space affects both customers and regulatory compliance.
We provide preventive maintenance contracts for commercial property managers that include annual backflow testing, water heater inspection, valve condition assessment, and drain system inspection — catching developing problems before they become emergency disruptions.

Commercial Plumbing Maintenance Contracts
Planned maintenance is more cost-effective than reactive repair for commercial plumbing systems. A restaurant that schedules monthly drain cleaning avoids the emergency weekend call that costs three times the planned rate and disrupts revenue. An office building that schedules quarterly plumbing inspection and valve testing avoids the main shut-off failure that creates an insurance claim and tenant displacement.
Our commercial plumbing maintenance contracts are structured around the specific needs of the business type. A restaurant contract includes monthly kitchen drain cleaning, quarterly grease trap pumping, and annual backflow preventer testing. An office building contract includes quarterly valve testing, annual water heater inspection, and semi-annual fixture inspection across all washroom facilities. Each contract is customized to the property size and operational profile.
Contract clients receive priority dispatch for emergency commercial plumbing calls — their calls queue ahead of non-contract emergency callers during periods of high demand. This priority access is most valuable during spring storm season when emergency drain calls peak across Mississauga and response times for non-contract clients can extend.
All commercial maintenance visits generate detailed service reports documenting the work performed, the condition of all inspected systems, and any items requiring attention at the next visit. These reports are formatted for inclusion in the building operations and maintenance file — a requirement for commercial property insurance audits and due diligence documentation during property sales.
Multi-Unit Residential Plumbing
Multi-unit residential buildings present distinct plumbing service requirements. The system serves dozens to hundreds of individual units with shared stacks, shared domestic hot water systems, and shared amenity facilities. A single stack blockage or supply line failure can affect multiple tenants simultaneously, creating immediate habitability issues and liability exposure for the property manager.
We provide emergency response and planned maintenance service for multi-unit residential properties across Mississauga. Our commercial team carries high-capacity hydro jetting equipment for main stack cleaning and coordinates with building management for tenant communication and work access scheduling that minimizes disruption.
Domestic hot water recirculation systems in multi-unit buildings require periodic pump maintenance, heat exchanger inspection, and balancing valve adjustment to maintain consistent hot water temperature at all units. Buildings that skip this maintenance develop temperature and pressure complaints from upper-floor and end-unit tenants. The cumulative cost of resulting service calls exceeds the scheduled maintenance cost in most buildings over a three-year period.
Water sub-metering installation for condominium buildings — where individual unit water consumption is metered and billed to unit owners — requires licensed plumbing work to install sub-meters in the common mechanical room. Sub-metering is increasingly adopted by Mississauga condominium corporations as a conservation measure and a fair-billing mechanism. We install and commission sub-metering systems for buildings converting from bulk billing to individual consumption billing.
Same-Day Commercial Plumbing Service — Mississauga
Commercial plumbing emergencies do not wait for convenient times. A restaurant with a blocked kitchen drain at 6 p.m. on a Friday — before the evening service rush — needs same-hour response. Delex Plumbing’s commercial dispatch operates 24/7 for exactly this reason, with licensed commercial plumbers available immediately for the Mississauga Square One corridor, industrial areas, and all commercial districts.
We maintain dedicated commercial service vehicles stocked with commercial-grade drain equipment, larger-diameter pipe fittings, commercial backflow preventer test kits, and grease trap service equipment. Commercial plumbing requires tools and materials that residential vehicles do not carry — our commercial teams are equipped for the environments they serve.
Scheduled maintenance visits for commercial accounts are confirmed 48 hours in advance with the property manager. We arrive at the scheduled window, complete the work efficiently to minimize disruption to business operations, and provide same-day service documentation. For businesses with health code inspections, current service records are a compliance requirement.
After-hours commercial plumbing service is available for businesses whose operations require service outside standard hours. We schedule after-hours maintenance in advance and dispatch on-call plumbers for emergency commercial calls 24 hours a day at the same flat-rate pricing as daytime visits.
Why Mississauga Homeowners Choose Delex Plumbing
Delex Plumbing has built its reputation across Mississauga through 10 years of consistent service — same-day response, flat-rate pricing with no surprise charges, and licensed master plumbers on every job. Our 384 verified five-star Google reviews reflect the cumulative experience of homeowners from Port Credit to Meadowvale who called us once for a routine repair and have called back for every plumbing need since.
The three things our clients most consistently cite in their reviews: we arrived when we said we would, the invoice matched the quote, and the plumber left the work area clean. These are not exceptional standards — they are baseline professional standards that should characterize every service business. We treat them as the floor rather than the ceiling of what our service delivers.
Our flat-rate pricing policy means the quote we provide before touching anything is the amount on your invoice when we leave. No overtime charges for after-hours calls. No travel fees for distances within our service area. No material markups disclosed after the job is done. Transparent pricing is how we have maintained a 5.0-star rating across 384 reviews — clients who receive exactly what they were quoted do not leave one-star reviews.
We back every job with a written labour warranty. If something we installed or repaired fails within the warranty period, we return and fix it at no charge. No runaround, no dispute about scope. The warranty documentation is included with the invoice and specifies the exact duration and scope of coverage. For fixture and material warranties from manufacturers, we register the installation and provide the registration confirmation so warranty claims go smoothly without paperwork obstacles.
Licensed & Insured — Commercial Plumbing by Certified Professionals
Every plumber on the Delex team holds a valid Certificate of Qualification from the Ontario College of Trades. This licence is not a formality — it is the legal prerequisite for performing plumbing work in Ontario, and it represents a minimum of 9,000 hours of apprenticeship training plus a journeyman examination that tests both technical knowledge and code compliance.
Full liability insurance protects your property if any accidental damage occurs during our work. Bonded coverage protects you from any dishonesty by our employees while on your property. WSIB coverage protects you from any liability if a worker is injured on your property. These are not optional additions to our service — they are standard protections that every legitimate plumbing company carries and that unlicensed operators routinely lack.
We pull permits for all work that requires them. Ontario Building Code requires permits for new plumbing installations, changes to drain and vent systems, and water heater replacements. A job done without a required permit leaves you without a legally completed installation — a disclosure obligation in real estate transactions and a potential coverage issue in insurance claims. Our permit fees are included in the project quote rather than added as a surprise at the end.
