Commercial Plumbing vs. Residential Plumbing: What's the Difference?

While many people assume that the differences between residential and commercial plumbing are huge, much of it really comes down to scale.  Residential plumbing includes sinks, toilets, appliances, drains, pipes, and water systems for a home, but commercial plumbing expands on those basics with larger and more complex systems.

Similarities & Differences of Commercial Plumbing and Residential Plumbing

Size. One of the biggest differences is size. Residential plumbing systems serve fewer people and are generally smaller and less complex. Commercial plumbing, on the other hand, is built for larger buildings with many more users, both tenants and visitors. Because of this, the systems are larger, sturdier, and designed to handle much heavier use.

Usage. How the systems are used also sets them apart. A home typically averages about 88 gallons of water per day. Commercial spaces use far more, especially during the workday when activity is at its peak. Residential plumbing, meanwhile, tends to see heavier use in the evenings and on weekends.

Complexity. Commercial and residential plumbing also differ in the complexity of their systems.  Residential plumbing is normally limited to 1-2 floors and has more straightforward plumbing setups with toilets, sinks, and showers. Commercial systems can span multiple floors and include additional fixtures like urinals, water fountains, and more.

Equipment and Materials. Because residential and commercial plumbing systems operate on different scales, the equipment and fixtures they rely on aren’t quite the same. In commercial spaces, you’ll often find high-flow toilets, large water heaters, boilers, or booster pumps built to handle heavy use. Tackling these systems also calls for specialized tools that can keep up with the complexity of the job.

Scheduling and Access. Plumbing work in homes and businesses also happens on different schedules. For residential jobs, plumbers usually work during the day with some flexibility for emergencies or a homeowner’s availability. Fixtures in homes are easy to reach, which helps projects wrap up faster. Commercial plumbing, however, is a different story. Repairs and installations could be scheduled after hours to avoid disrupting business, and reaching the systems themselves can be more challenging. That added complexity often means projects take a little longer.

Regulations. Residential and commercial plumbing are each governed by a different set of regulations. While residential plumbing follows standard safety codes, commercial plumbing must meet regulations regarding safety, public health, accessibility, and the environment. Experienced commercial plumbers are well-versed in these regulations and can be a valuable partner in keeping buildings safe and compliant.

In other words, a commercial space isn’t just a bigger house. Because of the differences in the systems used in homes and commercial spaces, the plumbing needs are different, and so are the services needed to keep everything running smoothly.

Common plumbing services for homes include problems such as:

• Fixing backups, blockages, or clogs
• Installing or repairing hot water heaters
• Stopping leaks and toilet plumbing issues
• Repairing burst pipes and root infiltration

Common plumbing services for commercial spaces include problems such as:

• Repairing water, sewer, and gas lines
• Repairing or replacing large boiler systems
• Snaking complex lines to clear clogs
• Cleaning drains and grease traps
