The straight sections of plumbing systems are called "pipes" or "tubes". A pipe is typically formed via casting or welding, whereas a tube is made through extrusion. Pipe normally has thicker walls and may be threaded or welded, while tubing is thinner-walled and requires special joining techniques such as brazing, compression fitting, crimping, or for plastics, solvent welding. These joining techniques are discussed in more detail in the piping and plumbing fittings article.
“Central Penn Plumbing provided outstanding customer service. On a cold winter Saturday morning, we woke up to a very cold house. I gave Central Penn (Scott) a call and within an hour he had a service technician at our house to address the issue. Not only did they resolve the issue on the weekend, but Scott stopped by later in the week to ensure that things were still ok. Outstanding customer service. Thanks Central Penn Plumbing Services!”
Rooter service is designed to solve the commonplace problems of slow and clogged drains. Clogs and blockages can affect your plumbing in many ways, depending on the type of clog and where it is located. A clog inside one of your home’s drains will typically only affect the appliance or fixture nearest its location; these clogs are often comprised of organic debris such as food scraps, hair, and soap scum. Alternatively, a larger clog blocking your home’s sewer line may show different symptoms, such as widespread drainage issues in several areas of your home or minor backups in tubs and showers when a toilet is flushed or your washing machine runs. In severe cases, you may experience wastewater backups that flood your home, causing damage and exposing family members to untreated sewage. Sewer clogs can also be due to debris buildup or non-flushable items in the pipes, or may instead be caused by tree roots invading and growing into your sewer line in search of water, forming a living, growing clog that cannot be removed without the help of your professional rooter service.
Master plumbers on construction jobs may be involved with developing blueprints that show the placement of all the pipes and fixtures. Their input helps ensure that a structure’s plumbing meets building codes, stays within budget, and works well with the location of other features, such as electric wires. Many diagrams are now created digitally with the use of Building Information Modeling (BIM), which allows a building’s physical systems to be planned and coordinated across occupations.
Specialized plumbing tools include pipe wrenches, flaring pliers, pipe vise, pipe bending machine, pipe cutter, dies, and joining tools such as soldering torches and crimp tools. New tools have been developed to help plumbers fix problems more efficiently. For example, plumbers use video cameras for inspections of hidden leaks or problems, they use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench-less sewer line replacement.
