It is an interesting and complex job
According to John from plumbingjohnscreek.org Being a commercial plumber is like being a residential plumber, with one exception. The commercial plumber works on a larger scale. You may have seen your local plumber at work and think that all they do is install sinks, toilets and pipes. But a commercial plumber’s job goes beyond the basics.
#1. They do install toilets, sinks, and pipes
But these duties are far more complex, especially when the commercial plumber is working on a mall construction project. Not only is the pipe route difficult and complicated, the commercial plumber has to provide the right equipment and other plumbing needs for any commercial kitchens installed in the mall.
#2. They install sprinkler systems
Commercial plumbing is more than toilets and sinks. They are responsible for setting up a building sprinkler system. Often they have to work around the false ceiling framework to make sure that only the sprinkler heads are visible. They also have to double check to make sure their work and equipment meet fire and building codes.
#3. They work with pressurized water and drains
Before they do the interior plumbing work a commercial building requires, the commercial plumber must make sure that the building is properly connected to the city water system. They also must make sure that all the drains are connected correctly and that no waste is able to escape the system. The commercial plumber must also double check their work to make sure all drains and water supply lines are connected correctly and are doing their job.
Some final words
This brief look into the world of the commercial plumber reveals that their work is complex and at times quite difficult. It takes skill, experience and knowledge to be a commercial plumber.
