For commercial work, tell the contractor the building type, whether you need work done outside business hours, and whether you need backflow testing or grease trap service. Ask for proof of commercial liability insurance and the Maryland license held by the master plumber on the job.

Backflow testing
Backflow preventers stop contaminated water from flowing back into the public supply. Water utilities require commercial assemblies to be tested on a schedule, usually yearly, by a certified tester, with results filed with the utility. See backflow testing and prevention for who needs it and what happens when an assembly fails.
Restaurant plumbing repair
Grease is the leading cause of restaurant drain backups. Regular hydro jetting of kitchen lines and keeping grease interceptors on schedule prevents most emergency closures. Restaurants also rely on fast repairs to dish machines, booster heaters, hand sinks and floor drains, plus annual backflow tests, and many plumbers will work before opening or after close.
Multifamily plumbing maintenance
Apartment and condo buildings share risers, drain stacks, water heaters and booster pumps, so one failure can affect many units. Owners and managers often schedule preventive work: jetting main drains, flushing water heaters, testing backflow assemblies, exercising shut-off valves and inspecting for leaks between units. Tell the plumber who provides access and who approves quotes.
Industrial and warehouse facilities
Warehouses and light industrial sites in areas such as Jessup, Hanover, White Marsh and the Port of Baltimore corridor need restroom and break-room plumbing, backflow protection on process water, and repairs to larger water and drain lines. Describe the facility and equipment when you call, so we can connect you with a contractor who handles that scale of work.
