05/27/2014 A plumbing system is used to safely transfer liquids and gasses to and from a building and its site. Water plumbing fixtures, and waste piping may be the most common types of plumbing systems within a building, but other types of plumbing system may be a required, including plumbing for gas service.
Plumbing systems directly affects the health and safety of the public, and are distinguished from other piping systems by the following requirements:

• The design, material, and installation of the systems are directly regulated by a plumbing code.
• System design must be approved by an authorized plumbing code official charged with assuring code compliance.
• A permit for installation of the system must be obtained from authorities having jurisdictions.
• Systems should be installed by an entity duly licensed by local authorities to install plumbing system.
• Plumbing design plans and installed systems are required to be inspected and approved by an authorized code official charged with code enforcement.

When sustainable design is a concern, addressing rainwater and site drainage issues should also be part of the early planning process, the existing utility condition and infrastructure (storm drainage, water utilities, and sanitary sewage utilities) need to be considered.
Other issues that should be considered in the design of the residential plumbing system include the control of noise, vibration, and piping condensation:

• Noise is a factor of high-velocity liquid flow in pipes of fixture noise.
• Vibration is the result of mechanically coupling pipes to moving equipment (such as pumps), as well as the manner in which piping is physically isolated from the building structure. Structure borne noise can propagate very efficiently.
• Condensation occurs when exposed or insufficiently, insulated pipes cooled by their content pass through warm, moist are and the exterior of the pipe reaches the dew point temperature.

The best components of a plumbing installation (water distribution and sanitary waste drainage system) are as follows:

• Service tab
• Meter
• Shut-off valve
• Service entry
• Fixture supply tree
• Fixture
• Trap
• Drain
• Venting waste piping
• Clean outs
• Building trap
• Sewer connection
