A plumber is often called in to repair malfunctioning appliances, machines and systems. Troubleshooting is the process of identifying and addressing problems that arise unexpectedly, such as equipment breakdowns or software bugs. The term “troubleshooting” is believed to be derived from the stories of gold rush guards and technicians who hunted down equipment failures by “throwing salt into the machine”.

Plumbers use a number of diagnostic tools when assessing an issue. These can include asking specific questions, conducting a physical inspection and analyzing the results of other diagnostic tools. The goal is to identify the cause of the problem and find a solution that will prevent it from occurring again in the future.

Some common plumbing issues are clogged toilets, leaky pipes and low water pressure. While fixing these issues may be relatively straightforward, finding the root cause can be much more difficult. For example, a blocked drain could be caused by many different things, including excessive toilet paper, foreign objects or food waste. In such cases, a plumber would need to disassemble the toilet and examine its inner workings. Then, they would need to determine where the blockage is located and remove it.

Other problems might involve high water bills or a malfunctioning garbage disposal. In these instances, a plumber might need to run water in other areas of the home to ensure that there are no additional blockages or leaks. They might also use tools such as infrared thermometer guns to detect hot or cold spots on the surface of pipes.

The troubleshooting process is often lengthy and time-consuming. However, it can save a lot of money and inconvenience in the long run. A good plumber will take the time to thoroughly investigate the problem and resolve it in a timely manner.

It is important for troubleshooters to document every step of the process. This includes describing the initial problem, listing all potential causes and testing them, and identifying the final solution. Documentation is useful for multiple reasons, including preventing future issues and improving the overall quality of the work. It is also a good way to improve efficiency by making the troubleshooting process more repeatable and reliable.


During repairs, plumbers use their knowledge of plumbing systems to fix issues with water supply, waste disposal, and more. They may repair leaky faucets, toilets, and pipes; install new fixtures like bathtubs, sinks, and shower heads; or inspect, test, and clean drain lines. A plumber needs to have certain soft skills to succeed in this occupation, including the ability to listen and communicate effectively. They also need to be organized and able to work under pressure.

One of the most common repairs plumbers perform is fixing leaky pipes. They may use repair sleeves to temporarily mend leaks, or they might replace the entire pipe section if it is beyond repair due to corrosion or damage. Plumbers can also use epoxy putty to seal leaking joints. Before applying the putty, however, a plumber should make sure that the surface is dry and free of any contaminants.

Another issue plumbers frequently repair is low water pressure. This is usually caused by clogged or damaged pipes, so the plumber might use a snake to remove obstructions from the line. They might also check the water meter to see if there is a problem with the flow rate.

In some cases, the plumber may need to drain and flush the toilet to fix a clog or backflow. This can cause significant disruptions to a home, so it is important that the plumber shut off the water supply before beginning any work. This can typically be done by turning off the main water valve located at the water meter, or by using a local shut-off valve near the problematic area. It is also a good idea to open all faucets and outside spigots in order to drain the system and reduce pressure during the repair process.

Finally, if the plumber is working on a gas line, it is vital that they use caution and follow all safety protocols. This includes wearing protective clothing, using a gas mask, and having a licensed professional perform the work. It is also a good idea to move any furniture or appliances away from the line, and to drain any gas-related appliance like a dryer or stove before starting work.
