Residential plumbers install, connect, and repair pipes, fixtures, and appliances like sinks, toilets, faucets, showers, and water heaters in homes. They also inspect plumbing systems for leaks, clogs, and other problems, using specialized tools to diagnose issues. Residential plumbers often work on sewer lines as well, installing backflow preventer devices to protect drinking water from contamination and repairing broken or damaged line sections.

When they’re working on installations, residential plumbers must adhere to building blueprint specifications and use a variety of tools to complete the job, including pipe cutters, soldering guns, and pipe-threading machines. They may also assemble and cut tubing, join pipes with threaded joints or flanges, and use caulking to seal leaks. Plumbers also may need to replace old galvanized pipes with new PEX or PVC piping, as galvanized pipes are more prone to corrosion and rusting.

Another service that residential plumbers offer is drain cleaning and unclogging. When a homeowner notices a problem with their drain, they call their plumber for an inspection and repair. This can include anything from clearing out a simple clog to replacing a whole fixture like a bathtub or toilet. If the plumber discovers a serious issue, they may need to dig up parts of the plumbing system and remove them for further inspection and repairs.

The primary difference between commercial and residential plumbers is their scope of work. While both may repair leaks and install or repair appliances, residential plumbers usually only deal with plumbing in homes and apartments. Commercial plumbers, on the other hand, work in larger spaces like office buildings and shopping malls. They may have to work with a wide range of plumbing fixtures and equipment for varying uses, and they must comply with strict health and safety regulations when working on plumbing for restaurants and other public spaces.

One of the most important factors to consider when choosing a plumber is their reputation and experience. Check online reviews and ask friends and family for recommendations. Look for plumbing companies with years of experience and a team of certified, professional plumbers. It’s also a good idea to make sure that your plumber is licensed and insured by checking with your city or state’s department of buildings.


Residential plumbers repair and service plumbing fixtures and systems. They may install new fixtures, like toilets or garbage disposals, or they may replace old ones, such as corroded or worn-out faucets. Plumbing services also include inspecting and maintaining existing pipes and fixtures, such as clogged drains and sewer lines. Plumbers use a variety of tools to perform these tasks, including snakes, augers, and hydro jets. They also troubleshoot and diagnose problems, such as low water pressure or temperature fluctuations.

Commercial plumbers are similar to residential plumbers, but they work on larger systems in places like hospitals, restaurants, and malls. These systems have more complex layouts and require more extensive training and knowledge of building codes. Commercial plumbers are also responsible for repairing and installing gas lines, which must be done according to local and state regulations.

Plumbing leaks, clogged drains, and sewer line problems can all be disruptive to your home. If left unchecked, these issues can lead to expensive repairs and replacements. Residential plumbers can help you resolve these problems quickly and efficiently.

Leaking drain lines can cause flooding, while backed-up sewer lines can damage your home’s walls and floors. If you notice any of these issues, call a residential plumber right away.

A reputable plumbing company should offer a wide range of residential plumbing services, from replacing a faucet to re-piping your entire house. Their technicians should be licensed and insured, and they should have experience working on homes of all sizes. If you have any questions, feel free to ask the plumbers before hiring them.

In addition to repairing and replacing pipes, faucets, and fixtures, a residential plumber can also install new appliances, such as dishwashers and washing machines. They can also inspect and maintain existing appliances, like water heaters, to ensure that they are safe and working properly. They can also handle more complicated jobs, such as rerouting sewer lines or replacing a septic tank system. These jobs are usually more expensive and require specialized knowledge and equipment. A plumbing contractor should be able to provide you with an estimate before beginning any work.


Residential plumbers are often the first to come into contact with a customer’s plumbing problems, because they focus on the pipes and systems that run throughout the home. This means that they are responsible for repairing and maintaining water heaters, kitchen sinks, bathroom sinks, bathtubs, showers, and other household fixtures. They may also troubleshoot and fix clogged drains, toilets, and sewer lines.

As a result, they must have strong problem-solving skills to diagnose issues and come up with creative solutions. They typically install a variety of pipe sizes and types, including copper and PEX, and they are familiar with various water-related building codes. Residential plumbers may also perform routine maintenance tasks, such as snaking drain lines and replacing washers and o-rings.

Commercial plumbers deal with much larger and more complex plumbing systems. Their work is more demanding, requiring advanced knowledge and training that isn’t always gained in an apprenticeship or formal schooling. Commercial plumbers are also familiar with a higher level of health and safety standards that must be met in commercial spaces, such as those found in restaurants or hotels.

For example, if there is a plumbing leak in a restaurant space, it needs to be quickly fixed to avoid any food or drink contamination. This is important, and it’s something that only a trained professional can do.

The bigger difference between commercial and residential plumbing, however, is in the size of the systems they are dealing with. Commercial spaces have multiple floors and numerous sinks, toilets, and urinals, all of which require more sophisticated plumbing systems to accommodate the higher usage rates than residential buildings.

Because of the differences in size and complexity between commercial and residential plumbing, it’s crucial that customers find plumbers who are experienced in both. This will ensure that they are getting the best service for their money, regardless of whether they need a simple drain snaking or a brand-new water heater installation. To ensure this, customers should ask plumbers about their previous experience with both types of plumbing. For example, they should ask about any jobs they’ve completed in commercial or industrial spaces.


While it is often easy to assume that any plumber will work well enough for your plumbing problems, it is important to remember that not all plumbers are created equal. Choosing a residential plumber with the right experience, skills, and licenses will ensure that your pipes continue to function smoothly for years to come.

A licensed residential plumber has the ability to install, repair, and replace plumbing fixtures such as sinks, toilets, bathtubs, showers, faucets, drains, and pipes.

If it is time to replace your water heater, they can assist you with choosing a new model and installing it for you.

Although most people don’t think about their plumbing systems until something goes wrong, it is important to keep up with routine maintenance to prevent issues and prolong the life of your pipes. A reputable and qualified residential plumber can handle all of your maintenance needs for both interior and exterior pipes, including backflow testing, hydro jetting, and pipe insulation.

There are many different ways to get a job as a plumber, but most start off their careers by participating in an apprenticeship program. This allows them to learn the trade while working on real-life projects alongside seasoned professionals.
