Although it may seem simple, plumbing is a complex process. So how does plumbing work? The answer to this question may seem self-explanatory, but there is a great deal more that goes into it. So, let’s start with the basics of how plumbing works.


All plumbing systems are composed of two separate systems, one to bring fresh water in and one to take wastewater out. Although completely separate systems, plumbers are experts on both.

Incoming System

The incoming water is controlled by the main valve that has the ability to shut off all water, and there are other valves located throughout the system that can shut off individual lines. As water is brought into the home or building, it requires pressure to make it to all areas of the building. Therefore, a break or leak can cause a lot of damage due to the high amount of water and pressure. This may result in mold or other water damage and requires emergency plumbing service. Incoming water is cold, so a water heater is required to get the temperature range in showers and sinks.

Outgoing System

Wastewater, also known as sewage, is the content that needs to be cleared in order to maintain a clean and sanitary environment. Wastewater leaves through pipes to either a sewer or septic tank. Sewers are used most of the time, especially in urban areas, while septic systems are used in more isolated locations. Damages to sewer lines can cause a variety of problems, including substantial health issues, due to the contaminants within the water.

Things to Know

First and foremost, plumbers are experts on all things plumbing. If you ever have any concerns or questions, the best thing to do is call your plumber. There are a lot of risks that could occur when trying to “DIY” your plumbing. Although it may seem cost-effective to fix an issue that occurs yourself, a small mishap could lead to a great deal of damage and money to reverse it.
