Gas Plumbing Introduction


About Gas


Natural gas, or gas:


  • Is a fossil fuel composed almost entirely of methane
  • Contains small amounts of other gases, including ethane, propane, butane and pentane
  • Is often called ‘natural gas’ because it is a naturally occurring hydrocarbon (i.e., a particle made of hydrogen and carbon atoms)
  • Is a widely used source of energy in homes for heating, cooking and washing
  • In its natural state is odorless, colorless and flammable
  • Has odorants added during distribution to make it detectable using human olfaction capabilities or more simply, the sense of smell


British Thermal Units


Natural gas, like other forms of heat energy, is measured in British thermal units or BTU. One BTU is equivalent to the heat needed to raise the temperature of one pound of water by one-degree Fahrenheit at atmosphere pressure.




A cubic foot of natural gas has about 1,027 BTUs. However, consumer bills are usually measured in heat content or therms. One therm is a unit of heating equal to 100,000 BTUs.


Gas Odor


In its original state, natural gas is odorless and colorless.  The highly recognizable and unpleasant smell of gas is attributable to gas distribution companies adding odorants that smell like rotten eggs through a process known as odorization.  Odorants are sulfur compounds like ethanethiol or mercaptan which are expressly added to make gas leaks easily detectable. 


Gas Plumbing


Gas plumbing is anything that involves the installation and maintenance of natural gas lines and pipes for homes and businesses.  The residential gas plumbing system, known as the Gas Delivery System (GDS), is the gas plumbing between the gas meter and a home’s gas type appliances.  The GDS has two primary components including the:


  • Gas Line (GL) – the underground gas pipe that runs between the gas meter and the connection to the Gas Supply System
  • Gas Supply System (GSS) the intra-building pipes that delivery gas to gas consuming appliances


Some of the most common gas appliances are:


  • Water Heaters - An appliance that heats water above its ambient temperature.  A natural gas water heater is an extremely efficient way to heat water and heats water twice as fast as an electric water heater of the same size and rating
  • Gas Range – A gas range is a large cooking stove in which the combustion of gas is used as the source of heat and is a popular way to cook because it heats quickly and allows instant and infinite temperature control
  • Gas Barbeque Grill – A barbecue grill is a device that cooks food by applying gas generated heat from below. There are several varieties of grills, with most falling into one of two categories: gas-fueled or charcoal.
  • Gas Fireplace - A fireplace is a structure made of brick, stone or metal designed to contain a fire.  The fire inside the unit is real and operates in a similar fashion to a gas-oven. The burner is hidden by the logs that enable the flames to spread. Gas fireplaces are used for the relaxing ambiance they create and for heating a room
  • Gas Clothes Dryer - A clothes dryer is a powered household appliance that is used to remove moisture from a load of clothing and other textiles, usually shortly after they are washed in a washing machine.  With a gas dryer, air is first drawn into the dryer, and then passes through a gas fueled heating apparatus that warms the clothes in the tumbler, and then collects the moisture and exhausts it out of the dryer via a venting system.

Gas Safety


If you smell rotten eggs or a sulfuric smell, this is a clear indication that you have a gas leak.  Caution is the best policy when it comes to gas leaks; the slightest spark, even a static shock can cause the leaking gas to explode.


Gas Leak Safety Tips


If you suspect a gas leak, follow these safety tips:


  • Do not attempt to locate the leak yourself
  • Leave the vicinity immediately but do not use an automated door.  Leave the door open behind you to ventilate the premises
  • Warn others to leave the premises, and do not allow others to enter
  • Do not turn off or on any electric switches, thermostats, or appliance controls - they may cause sparks that can ignite leaking gas
  • Do not start or stop an engine
  • Do not smoke or use any open flames
  • From a safe distance, call the Gas Company and 9-1-1
  • When digging outside, if you damage a natural gas line, call the utility immediately.  Do not attempt to repair the line yourself
  • Contact GPS Plumbing when the Gas Company shuts off the gas and determines that the gas leak is somewhere beyond the gas meter and the repair is now the responsibility of the building owner
