The Difference Between Commercial and Residential Plumbing

The Difference Between Commercial and Residential Plumbing

Commercial plumbers specialise in maintaining, repairing, and installing water infrastructure on commercial properties. Whether the plumbing system is found in a home, an office or a commercial building, it has the same goal; to deliver clean water and remove waste. The difference between commercial plumbing services and residential plumbing comes down to the requirements put on each system. Commercial systems are designed to accommodate a large number of uses at the same time, which is why something like a strata building may be a residential building; it counts as a commercial plumbing job.

Regularity of Maintenance

Residential Plumber Sink

In residential plumbing, the system tends to be relatively easy to navigate. Commercial plumbing is much more complicated; multiple floors, bathrooms, sinks, and piping systems exist. The complexity of the systems means it is advisable to have a commercial plumbing contractor come to service your commercial plumbing. Plumbing issues in residential situations tend to be different versions of the same problems; bathrooms and kitchens. Commercial plumbing issues, on the other hand, tend to be much more complex.


Common sense is vital when it comes to checking for leaks, and one the significant signs are mould and mildew. Check the backs of cupboards and under sinks for signs of mould or any smells that may indicate a leak. Finding these leaks early can save you thousands of dollars in repairs if they can be caught early. A minor mould or mildew in a shower can occur at any time, but finding it outside the bathroom area, on walls or floors, is not expected unless you have a leaking pipe.

Safety Requirements

Commercial Plumber Inspection

Commercial plumbing is held to a much higher standard than residential plumbing. Though residential plumbing must meet common safety standards, commercial plumbing is held to a higher standard. Additional tests and inspections are required on the commercial level. This can include thermostatic valve testing, backflow prevention testing, trade waste treatment, and amenities maintenance and alterations.


Unlike residential plumbing, where you often-times have the ability to wait for a plumber and can find workarounds in the meantime, this is not a viable option for commercial plumbing issues. If a bathroom gets clogged in an office building, then under Queensland law, the staff must be sent home, leading to significant disruption to workflow.
