All About Plumbing: Pipes, Fixtures, and Drains

Plumbing is an industry that entails installing, maintaining and modifying piping systems. It can also include alterations to appliances and venting systems, as well as public water supply systems. This field, however, does not include drilling water wells, installing water softening systems, or manufacturing plumbing fixtures. Plumbing systems are made up of three main components: an adequate water supply system, a safe drainage system, and plumbing fixtures.

Water supply

The plumbing system in a home includes a variety of pipes, each with its own unique set of characteristics. For instance, sewer pipes are typically thicker than water supply pipes, and they are often made of plastic or durable metal. Unlike water supply pipes, sewer pipes rely on gravity to remove waste, rather than pressure. They also must be angled at a particular degree to allow liquid and solid waste to pass through. If they are not angled correctly, they can develop clogs and leaks.

The main water supply in a home is divided into two parts: a cold water pipe and a hot water pipe. These two pipes are often parallel and are connected to one another. The waste drainage system uses gravity to channel wastewater to a septic tank or sewer. This system includes copper, HDPE, and CPVC pipes.

The pipes used for the water supply in a home must be marked with a safety symbol. These symbols must be found at the entrance and exit of every water supply pipe to a dwelling unit. Plastic pipe is a good choice for water supply lines since it is relatively inexpensive and easy to install. However, it is not suited for use as a water supply pipe in some areas.

For a plumbing system that includes a water supply, cross-linked polyethylene (PEX) is a popular choice. It is resistant to corrosion and rust, and has a low cost compared to rigid piping. PEX pipes are also easy to install, and they are also color-coded for easy identification.


When it comes to your home’s plumbing, there are several things to keep in mind. The main one is clogging. Clogged drains are common, and the best way to prevent this is to regularly clean the plugs and the pipe.

These leaks can cause mold and odors to build up in the room. They can also lead to structural damage to the house.

Drainage pipes come in many varieties. Polyvinyl chloride (PVC) pipes are a common choice for drainage projects. These pipes can be made in a variety of sizes and are resistant to chemicals. They are also recyclable. However, they tend to be less flexible than other types of pipes.

The type of drainage pipe you need depends on the situation. Some pipes take in water through joints, while others are perforated. You must make sure you choose a pipe with good strength and ease of installation. This way, you can save time and money. Once you know the basics of plumbing, you can learn how to make repairs when needed.

Polyvinyl chloride (PVC)

Polyvinyl chloride (PVC), a thermoplastic material, is a great choice for plumbing. It is inexpensive, durable, and chemically inert. It is also easy to install and dismantle. Another benefit is that PVC can be recycled and reused for other purposes. In Europe alone, about eight thousand tons of PVC are recycled each year through the VinylPlus program.

Despite the benefits of PVC piping, it is limited in certain applications. In Massachusetts, the state’s plumbing code prohibits the use of PVC in residential buildings up to 10 stories tall. Fortunately, most home supply stores carry a complete line of PVC joints, pipes, and fittings.

Another benefit of PVC is that it is flexible and lightweight. It is commonly used for water supply and drains, though it should never be used for hot water. In addition, PVC is rated differently for different applications. For example, schedule 35 PVC is meant for sewer and water service, while schedule 80 is used for high pressure applications. Some PVC pipes and drains are also available with foam cores.

Polyvinyl chloride is a synthetic plastic. The material is lightweight and highly resilient. It is made from a chemical reaction that can produce many different products. In addition to pipes and drains, PVC can be used to make a variety of other products, including inflatable items and electrical cables.

Polyvinyl chloride is among the most popular types of plastic plumbing pipes in the United States. It is inexpensive to install and is extremely durable, lasting up to 70 years. In addition, it is also recyclable. Most PVC pipes are free from bisphenol A, making them safe for the environment. Additionally, PVC pipes are easy to work with. Different PVC sections can be attached with pipe fittings, cement, or glue.

Polyethylene cross-linked pipe (PEX)

When using PEX pipes for pipes and drains, it is important to choose the right type for your project. The most common type is push-fit, which means you don’t have to worry about soldering. But you should avoid installing PEX in confined spaces because it tends to expand. Rather, install it in loops to allow for expansion and contraction. Moreover, it’s best to use plastic straps instead of metal ones.

Polyethylene cross-linked pipe (PEX), which is also known as polyethylene tubing, is made from high-density polyethylene (HDPE). This material contains a cross-linked polymer structure that makes it more flexible. The cross-linking occurs during the extrusion process, and the degree of cross-linking should be between 65 and 89%. If the cross-linking density is too low, the material can become brittle and may have poor physical properties.

The three types of PEX piping are Type A, Type B, and Type C. The first two types are flexible and easy to work with, while the third type is stiffer. Type A is more flexible and can be used for most water supply plumbing needs in a home. PEX-A also resists freezing and cracking in frigid temperatures. The only major disadvantage of PEX-A is its price, which is higher than that of PEX-B.

While PEX pipes have many benefits, they haven’t yet made their way into mainstream building practices. One common issue with PEX is that it tends to stiffen up in cold weather. Fortunately, there are standards for this type of pipe that addresses these concerns.


When installing PEX pipes, you should know that there are several different brands and materials, so make sure you select the right type for your needs. You also want to use the manufacturer’s connectors to prevent problems with leaks and water damage. Mixing materials may void your warranty and cause your pipes to leak or fail an inspection. It is also important to avoid making a mistake that could cost you a lot of money in the long run.

Before installing PEX, you should make sure that you follow the proper installation techniques. For example, run your main line from the outside of your home through the walls. Make sure you use holes every 16 to 24 inches and secure the line with special clamps. When installing PEX pipes, you can either install main lines to all fixtures or branches for each fixture. However, if you have a small space and want to reduce the number of connections, you should choose “home runs” instead of branching. This way, you’ll have only two connections per fixture, which will minimize leaks and reduce the risk of leaks.

Another advantage of PEX is its flexibility. It doesn’t freeze or expand like PVC, so it stays strong even in colder climates. This feature is especially important when installing a water supply line from the street to the house. If you don’t want to hire a plumber to install the water line, PEX pipes are the best choice.

If you’re building a new home, PEX pipes are a great way to save money. These pipes are made of cross-linked polyethylene, which is a flexible plastic material. You can find them at any home improvement store in the plumbing aisle.
