A service riser is the vertical sections of a service pipe used to supply gas to a building, including any horizontal sections of the service pipe between such vertical sections. An installation pipe is a pipe used to supply gas to a particular consumer, including any gas fitting used in connection with the pipe except a service pipe and a pipe comprised in a gas appliance.
As owner of a service riser and an installation pipe (the actual ownership can be found in the deed of mutual convenant), you have a duty to arrange for regular inspection and maintenance of your gas installations to protect yourself and the public against unnecessary gas hazard. If any gas pipes may cause danger due to lack of maintenance, the gas supply company may suspend gas supply to the building for safety reasons.
Generally speaking, a service riser and an installation pipe should be inspected and maintained every 18 months to ensure that the gas pipes are in good condition. The owners of gas installations shall arrange a registered gas installer employed by a registered gas contractor to carry out regular inspection or maintenance for their gas installations. A list of the registered gas contractors is available on the EMSD website.
