Commercial Plumbing

Keeping Michigan Businesses Running Since 1985

Putman & Sons Plumbing has been working with Michigan businesses since 1985. We help retailers, manufacturers, municipalities, and offices keep their buildings, bathrooms, sewers, and drains in top working order. Our commercial division operates under a Licensed Master Plumber and maintains full building code compliance on every project.

Commercial plumbing failures are not inconveniences — they are revenue events. A backed-up floor drain in a restaurant kitchen during Friday dinner service, a burst supply line in a manufacturing clean room, a failed backflow preventer that triggers a municipal violation: each scenario has a dollar-per-minute cost that residential work does not. Our commercial team understands this urgency and responds accordingly.

How Commercial Service Differs from Residential

Commercial plumbing systems operate at higher pressures, greater volumes, and under stricter code requirements than residential systems. A typical commercial building in Oakland County uses 3-inch or 4-inch copper or cast-iron supply mains versus the 3/4-inch residential standard. Drain lines are sized for peak simultaneous fixture use calculated from the Uniform Plumbing Code fixture unit tables — not estimated from household habit. We size, install, and maintain systems to these commercial specifications.
