Commercial Plumbing Services

Reliable Plumbing for Your Business

A plumbing failure at a commercial property isn’t just an inconvenience — it’s lost revenue, disrupted operations, and potential code violations. David Mechanical provides professional commercial plumbing services for restaurants, offices, retail centers, and light industrial facilities throughout the Chicagoland area. We understand the urgency of commercial plumbing and respond accordingly.

Restaurant and Food Service Plumbing

Restaurants put more demand on their plumbing than almost any other type of business. Grease-laden kitchen drains, high-volume dishwashers, commercial ice machines, and floor drains all need regular attention. David Mechanical provides grease trap installation and service, kitchen drain cleaning and hydro jetting, commercial water heater installation, and equipment plumbing connections for ranges, fryers, steamers, and dishwashers. We keep restaurant kitchens running so you can keep cooking.

Grease Trap Service

Illinois requires commercial food service establishments to maintain functional grease interceptors. A neglected grease trap causes drain backups, failed health inspections, and municipal fines. We install new grease traps to meet local requirements, clean and pump existing traps on a scheduled basis, and repair failed grease interceptors. We provide service records to keep your facility inspection-ready.

Backflow Prevention

Illinois state law requires annual backflow preventer testing at commercial properties. An untested or failed backflow assembly can result in fines and shutdown orders. David Mechanical installs, tests, and certifies backflow prevention assemblies for commercial properties throughout our service area, and provides documentation for your municipality and property records.

Office and Retail Plumbing

Office buildings and retail spaces need reliable restroom plumbing, functional breakroom fixtures, and clean water throughout. We handle restroom renovations, ADA-compliant fixture upgrades, water heater replacements, and all the routine repairs that keep a commercial building operating smoothly. We work with property managers and building owners on both planned maintenance and emergency response.

Light Industrial and Warehouse Plumbing

Warehouses, light manufacturing facilities, and industrial properties have their own plumbing demands — large floor drains, utility sinks, eye wash stations, compressed air line integration, and industrial water heaters. David Mechanical understands the plumbing requirements of these facilities and delivers reliable service with minimal disruption to your operation.

Preventive Maintenance Contracts

The most cost-effective commercial plumbing strategy is prevention. Our preventive maintenance agreements include scheduled drain cleaning, grease trap pumping, water heater inspections and flushing, sump pump testing, and backflow preventer certification — all on a schedule that works for your business. Clients on maintenance contracts experience fewer emergency calls and lower overall plumbing costs.
