If you’ve ever walked through a large city and wondered who does the plumbing for those massive skyscrapers, the answer is probably in this list of the 10 largest plumbing companies in USA.
To create our list, we have focused on the largest plumbing companies in the U.S. Before we start the ranking let’s give us some of your time to learn what these companies do and why these companies are so essential for our daily life. Plumbing came from the Latin word ‘plumbum’, which means lead because once upon a time pipes were made from lead. Plumbing jobs include pipes, tubing, and drinking water system fixtures along with getting rid of the waste. Plumbers fix or put in the new piping system, set equipment such as water heaters and do plumbing fixtures. Since we’re talking about building construction, you can also check our list of 10 top companies and best jobs for industrial engineers. The largest residential HVAC companies, as well as the largest commercial HVAC companies, play an important role in our daily life, all around the world. The industry makes a significant contribution to developing the economy as people need clean water and the safest ways to store and move their waste and trash. However, it must be noted that there is a huge difference between plumbing and sewage systems because plumbing only serves one building whereas a sewage system serves a lot of buildings.

HVAC companies are also essential for our daily life along with plumbing. HVAC stands for heating, ventilation and air conditioning, and these services are also needed while constructing a building. Most of the largest HVAC companies in U.S., as well as the largest HVAC companies in the world, also offer plumbing facilities. We have seen the list of the fastest growing HVAC companies and the best HVAC companies in US to check that if they have any plumbing services also. Insider Monkey experts have also looked into the list of HVAC companies in USA and made a list of 10 largest HVAC companies in the USA. Okay, now let’s come back to the plumbing. Plumbing was very rare in the early 19th century until people and the public health leaders wanted a better system for waste management. Before that, people just threw their waste in the river or down on the street which was very unhealthy (for obvious reasons).
Years of training and experience are needed to work with the largest plumbing companies. Plumbers with these companies must be experts on reading the whole building structure to determine the layout of water supply and waste management, while also finding faults in plumbing materials. A plumber has to deal with many things, such as acid waste, heating water, chilling water, natural gas, storm drains, new constructions, flush valves, floor drain, and ensuring safety standards on top of all that.
In order to compile this list, we have considered the company’s total revenue and the number of employees. We have collected the data from various trusted websites like Hoovers, Fortune 500, and Statista. The financial year 2016 is taken as the reference to collect all the data. While ranking the largest plumbing companies in the USA, we did not separate the biggest plumbing companies in the world from the largest plumbing contractors.
Based on these parameters, here is the list of 10 largest plumbing companies in USA.
