Grease traps, backflow testing, drain cleaning & code-compliant installations.
Commercial plumbing is a different discipline from residential work. The systems are larger, the codes are stricter, the failure consequences are more expensive, and the scheduling rarely allows for the kind of disruption that's acceptable in a single-family home.
Alliance Plumbing Services LLC operates a dedicated commercial division for businesses across Wilmington. The technicians assigned to commercial work are trained on commercial-specific systems — grease management, backflow prevention, commercial water heaters in the 100-gallon-plus range, sewer line work at scale, and the documentation requirements that come with operating in regulated industries.
What we're equipped to do for businesses in Wilmington
We service restaurants across Wilmington with technicians experienced in food service environments — commercial sinks, garbage disposers, water heaters sized for dishwashing, and health department compliant systems.
Scheduled pumping, full cleaning, line jetting, and proper documentation for health department records.
Camera inspection, large-scale equipment, and maintenance recommendations based on actual conditions.
Certified testing, installation, and regulatory reporting submitted on your behalf.
Large-volume tanks, recirculation systems, and minimal operational disruption during replacement.
Licensed commercial gas work and full new construction plumbing with GC coordination.
If your property falls into these categories, we will tell you directly and recommend a better-suited firm.
A restaurant operating in Wilmington came to us after a different plumbing company had recommended replacing their grease trap... Total cost was a small fraction of the replacement quote. The operation hasn't had a service-time backup in the eighteen months since.
Early morning, late evening, overnight, and weekend scheduling available. Multi-property operators can establish standing service agreements with priority dispatch.
