Commercial Plumbing Systems and Equipment We Service

Interstate AC installs, services, and supports the full range of commercial and industrial plumbing systems. Select a system below to learn more about our capabilities.

One Contractor for the Whole Building

Commercial plumbing is rarely one system. It is potable supply, sanitary drainage, storm drainage, gas distribution, hot water generation, and specialty process piping, each with its own code requirements and failure modes.
Managing that through multiple specialty contractors creates gaps, and gaps in plumbing tend to surface as water damage. Interstate AC covers the full range with licensed plumbers, specialty equipment, and the crane and rigging capability that larger installations require.

Water Supply and Distribution

Supply-side problems are the expensive ones. A failure here does not stay contained, which is why pressure monitoring and insulation review matter more in Middle Tennessee than the mild winter reputation suggests.

Drainage and Waste

Commercial drainage carries loads residential systems never see. Grease, paper, mineral buildup, and debris accumulate steadily, and the resulting blockage rarely happens at a convenient hour.

Hot Water and Treatment

Nashville water chemistry affects heater elements, fixture life, and appliance performance. Treatment is often the cheapest way to extend the life of everything downstream of it.

Gas Systems

  • Gas Lines and Gas Fitting
  • Kitchen equipment connections
  • Industrial and process gas distribution
  • Leak detection and line testing

Gas work is licensed, permitted, and inspected work. We handle the installation and the documentation together

Fixtures, Pumps, and Specialty Systems

Pump systems deserve particular attention. A below-grade ejector pump failure produces a sewage backup with no warning and no gravity assist working in your favor.

Every System, One Service Model

Whatever the system, our approach is the same: preventative maintenance to keep it running, responsive repair when something fails, and planned replacement when it reaches end of life. Buildings that need both mechanical trades covered can consolidate under a single HVAC and plumbing preventative maintenance agreement.

Frequently Asked Questions

Do you handle projects beyond standard plumbing work?

Yes. We handle large-scale pipe fitting and fabrication, large-diameter backflow replacement requiring crane support, commercial kitchen installations, industrial gas distribution, pump system replacement, and full facility retrofits.

Can you service systems in older buildings?

Yes. Older Nashville commercial properties frequently have mixed piping materials and undocumented modifications. Camera inspection and scoping let us work from what is actually there rather than from a drawing.

Do you handle backflow compliance testing?

Yes, including testing, documentation, repair, and replacement in accordance with local regulations.

Which system does my facility need?

That depends on building size, fixture count, water usage, and code requirements. Our team assesses the building and recommends a path rather than defaulting to what is already installed.

Not Sure What You Are Working With?

Our team can inventory your plumbing systems, scope what is not visible, and recommend a path forward. Contact us or call (615) 802-2665.
