Residential Plumbing Is Different From Commercial Plumbing

The Key Difference Between Residential and Commercial Plumbing Systems 

When it comes down to many factors, such as space, complexity, and purpose, a home's plumbing system is completely different from a plumbing system for a commercial space. Each system comes with its own set of advantages and disadvantages. 

To many, the differences are obvious. A commercial plumbing system must supply and carry away water from multiple systems. A single business can have tens of water fountains, sinks, toilets, and showers. A residence usually only needs to meet the plumbing needs of a single-family and may only support a handful of devices. 

However, when it gets down to the nitty-gritty, the differences are not necessarily visible to the untrained eye. By learning about the difference between these systems, both homeowners and business owners alike can extend the longevity of their units and prevent any undesirable issues. 

Size Matters When It Comes To Plumbing Systems 


Readers may be interested to learn that an office building can use 127 gallons of water per working day in a single day. Most water does not go to restrooms or cooling as some may think, but instead toward maintaining the building's landscaping. By comparison, the average home may not use this much. The average household uses about 100 gallons of water a day, usually going toward sinks, showers, and toilets. 

Commercial spaces are larger, involve more people, and require more intricate systems to work. They use much more water than the average family home, which contrasts nearly all of the aforementioned elements. 

Yet, just because homes are smaller than businesses does not mean homeowners should neglect their plumbing systems. Regardless of size, a professional should inspect the average plumbing system once a year – and perhaps even more in case of chronic problems. 

Commercial Spaces Are More Complex Than Average Family Homes 

Home plumbing systems are fairly standard. They're tasked with carrying in and carrying out water from homes' bathrooms, bedrooms, and kitchens. 

However, the plumbing system in the hypothetical strip mall has a much harder job on its hands. This is because every store comes with its own set of services, and a greater connection to sewer lines. Each individual business provides different services in a strip mall, meaning that they require different plumbing hardware to work effectively. A hair salon, for example, has different needs than a restaurant. 

With this information in mind, it is easy to see how a building's architectural design and complexity can need different systems than a single-family home. 

The More Complicated the System, the Bigger the Risk 

A plumbing system in a commercial building will see a lot more use than one in a family home. For instance, businesses typically have separate bathrooms for employees and customers. The size of a commercial building alone will require more copper pipes, drains, and mains than a house. 


With a complex plumbing system comes many moving parts. Even a small leak can upend the system altogether or result in costly expenses, much less a pipe burst. As such, these systems must be maintained.

An industry professional can assess the well-being of a system and determine whether any issues need addressing. They may also be able to provide insight into any preventative measures that could prevent problems in the future.
