South Boston Restaurant Commercial Plumbing Fit-Up: How Denommee Delivers Quality, Coordination & Long-Term Value

When a new 3,300 SF two-story restaurant project in South Boston, MA needed a plumbing contractor who could handle complex kitchen systems, tight timelines, and coordination across multiple trades, they turned to Denommee Plumbing, HVAC & Electric (DPHE).

This project includes a full commercial plumbing installation designed to support high-volume restaurant operations with multiple restrooms, kitchen gas systems, extensive drainage infrastructure, and exterior service connections. From the basement rough-in to the rooftop gas piping, Denommee’s experienced team is executing a scope designed to ensure performance and longevity.

Scope of Work: Commercial Plumbing Fit-Up

Denommee’s plumbing scope includes complete installation of sanitary, grease, domestic water, and gas piping systems for the restaurant space.

Underground and Basement Plumbing

• Installation of new sanitary and grease piping per P.1.0 drawings.

• Hot, cold, and recirculation copper water piping with ProPress fittings.

• DWV piping installation throughout basement per P.1.1.

• Integration with existing utilities and connection to the gas header.

Gas Piping

• Connection to existing gas system with 4”, 3”, and 2” gas piping.

• Installation of a new gas manifold in the first-floor kitchen.

• Four new 1” gas connections in the basement.

• Vertical 3” riser to roof, distributing gas to RTUs and kitchen equipment.

Water Heating and Grease Systems

• Installation of two commercial water heaters with 4” flues vented through the roof.

• One recirculation pump and two grease traps installed per plumbing schedule.

Fixtures and Equipment Installed

• 7 water closets (WC)

• 2 wall-mounted urinals

• 5 lavatories with hands-free faucets

• 2 hose bibbs

• 13 floor drains

• 18 floor sinks

• Backflow preventer, expansion tank, thermostatic mixing valve, trap primers, shock absorbers, and solenoid valves.

Kitchen Gas System and Rooftop Integration

This restaurant project includes a full kitchen gas system engineered for flexibility and capacity. Denommee is running black steel piping with Megapress fittings, teeing off in the basement to feed the water heaters, and routing a 3” riser up to the roof.

Rooftop & Kitchen Gas Scope:

• Tie-in to seven rooftop units (RTUs) and one ERU.

• Drops to hood and Ansul system.

• Gas piping feeds for sconces and a fireplace.

• High-integrity joints using Megapress fittings to minimize hot work and speed up installation.

This combination of precision piping and clean routing minimizes downtime during future servicing and ensures consistent performance for the life of the system.

Why Precision Plumbing Matters for Restaurant Projects

Commercial restaurant spaces demand more than standard plumbing—they require:

• High-capacity waste systems to handle grease and kitchen discharge.

• Reliable hot water and gas supply for kitchen equipment and dishwashing operations.

• Thoughtful routing and coordination to avoid future shutdowns.

• Code compliance and inspection readiness for fast project closeout.

Because these buildings are designed for heavy daily use, poor planning or installation shortcuts can lead to costly repairs, operational downtime, and failed inspections. Denommee’s approach ensures these risks are minimized from day one.
