Commercial Plumbing: What Businesses Should Know

Where commercial jobs differ from residential

• Higher fixture counts and larger drain lines
• Grease interceptors and grease traps in food service
• Backflow prevention devices with annual testing requirements
• Access, work often has to be scheduled around business hours or tenants
• Documentation, property managers usually need written scope, photos, and invoices

Common commercial calls

• Kitchen line clogs in restaurants, grease and food debris
• Multiple restroom fixtures needing service at once
• Water heater or boiler issues affecting hot water for the whole space
• Leaks between tenant units in multi-unit buildings
• Backflow preventer failures or missed annual tests

Preventative maintenance

Scheduled maintenance saves money over reactive repair. For restaurants that usually means regular grease line cleaning and interceptor service. For offices, periodic fixture and shut-off checks. For property managers, walk-throughs of common area plumbing and hot water systems on a set cadence.

Coordinating access

• Confirm hours and access points before dispatch
• Loop in property management or on-site staff
• Document work with photos for property records and any tenant billing
• Schedule disruptive work outside peak business hours where possible
