Every residential building has several plumbing systems that work to supply water and remove waste. Residential plumbing systems have components that draw out water from municipal water supplies or private wells and drain water to the municipal sewers or private sewage system. Aside from the waterworks within the home, these systems often have gas supply lines and exterior water systems that include landscape irrigation and drainage.
Interior Water Supply System
Interior water supply systems work to deliver water to the interior plumbing fixtures which include sinks, toilets, tubs, and showers. In general, they draw out water from various water sources, such as private wells and local water supplies. While private wells require pumping and pressurized equipment, local water supplies have pumps and pressurized equipment from the utility company. It is important to note, however, that neither private wells nor municipal supplies guarantee potable water. The plumbing materials usually used to deliver water are copper plumbing pipes, plastic pipes, and cross-linked polyethylene (PEX), depending on the area’s local code.
Exterior Residential Plumbing
There are two most common types of exterior residential plumbing systems being used today; these are the landscape irrigation systems and drainage systems. Landscape irrigation systems are those that employ series of plastic water supply pipes or drip irrigation tubes that deliver water to several sprinklers and faucets outside the house. Exterior drainage system includes gutters and buried drain pipes which prevent flooding and possible structural damage.
Drain, Waste, and Vent System
Drain, waste, and vent plumbing systems help remove wastewater from the house and vent the drain pipes to provide safe and proper drainage. Although this system performs multiple tasks, it appears as on central unit and are commonly made up of cast-iron drain pipes or plastic drain pipes known as ABS. Drain pipes are connected to plumbing fixture drains including that of sinks, toilets, and showers. Vent pipes, on the other hand, branch from the drain lines and protrude from the roof; allowing air to enter the system. Drain, waste, and vent drain lines will then deliver safe water or gray water, as well as sewage or black water to either private septic tanks or the local sewer systems.
Most of us think that plumbers only work with fixtures that involve water. However, they also do installation of pipes for the delivery of gas fuels which include natural gas and profane. Gas plumbing systems are primarily made up of black iron pipes. Compared to the soldered copper water supply lines and glued ABS drain lines, black iron gas pipes connect using threaded fittings. This plumbing system supply gas to several household appliances including ovens, stoves, as well as clothes dryer machines.
