Plumbing contractors can do more complex tasks than a plumber, such as constructing a building’s water or waste disposal system, install water heaters (gas or electric), and install gas connections. Plumbing contractors are needed professional installations such as backflow prevention, gas valves, and other waster system services.
Plumbing contractors act as consultants when clients are in their planning phases. They are also instrumental in ensuring that any maintenance or new construction is up to date with local, state, and federal regulation, as well as that commercial plumbing, adheres to all requirements of the Americans and Disabilities Act (ADA)
