Consumer piping systems are a system of pipes, pipe fasteners and things connected to the pipes that are used to carry gas from:
- the outlet of a meter to measure the consumption of gas on the premises to a gas appliance inlet
- the outlet of a gas storage tank or cylinder to a gas appliance inlet.
