A plumber working on commercial pipes.

Commercial plumbers provide essential services for businesses of all sizes. From installing water lines to repairing gas systems, a commercial plumber is responsible for ensuring that the plumbing in a facility or building runs smoothly and efficiently. 

They can also work with other trades, such as electricians and HVAC technicians, to ensure the proper installation of mechanical systems throughout a commercial property.

What certifications do commercial plumbers need?

Commercial plumbers typically need certifications from organizations such as the National Institute for Certification in Engineering Technologies (NICET) or the American Society of Plumbing Engineers (ASPE). Additionally, some states require commercial plumbers to obtain a Journeyman plumber or Master plumber level certification. This generally requires at least four years of experience working under a licensed professional and passing an exam.

What is commercial plumbing?

Commercial plumbing refers to installing, repairing, and maintaining plumbing systems in businesses such as restaurants, hotels, and other commercial buildings. This includes water lines, gas lines, drainage systems, and other components necessary for a business to function properly. 

There are several different types of commercial plumbing systems:

  • Commercial hot water distribution systems that provide hot water for sinks and showers
  • Sanitary drainage and sewer systems for carrying away waste
  • Stormwater drainage systems to control rainwater runoff
  • Fire protection sprinkler systems to protect against fires
  • Natural gas pipelines for supplying natural gas to heating systems or commercial appliances
  • Grease interceptors used in food service establishments such as restaurants and cafeterias

What do commercial plumbers do?

Commercial plumbers perform similar tasks and functions as residential plumbers but for commercial properties. Some of the more common job duties include: 

  • Install and replace plumbing fixtures such as faucets, toilets, sinks, and water heaters – Commercial plumbers are responsible for installing all the necessary pipes, lines, fittings, and fixtures to ensure a business’s plumbing system is functioning correctly. This includes connecting gas lines, installing water heaters, replacing old fixtures with modern ones, and connecting drain or sewer systems to public systems where needed
  • Diagnose and repair plumbing problems – Commercial plumbers must understand how different types of mechanical components interact to diagnose and solve complex problems related to commercial plumbing systems. This may involve troubleshooting issues with drainage pipe connections or other parts of the system before making repairs
  • Maintain drainpipes Commercial plumbers are also responsible for maintaining drainpipes by ensuring they are free from debris or blockages, which could lead to costly repairs down the road if not addressed promptly. This often involves regularly cleaning out drains using special tools such as snakes or augers to keep them clear of any buildup that could cause damage over time. 
  • Inspect new construction sites – Before any building can be occupied, it must first pass a final inspection by a commercial plumber who will check for proper installation of all necessary piping according to local codes and regulations set forth by governing bodies within their jurisdiction. They may also inspect existing buildings during renovations or remodels to ensure that all piping is up-to-date with current standards before occupancy begins again.
