Learning outcomes
By the end of this module, learners can:
- M04.1Trace the supply from the network to the installation and identify where responsibility changes.
- M04.2Locate and operate an emergency control valve and describe its labelling and access requirements.
- M04.3Explain how a meter regulator holds outlet pressure steady, and check the operating pressure.
- M04.4Identify common domestic meter types and the main requirements for meter installations.
Topics
- 4.1
From network to property: services and responsibility
The service pipe, the ECV, the meter installation and installation pipework, and who is responsible for each.
Draft - 4.2
Emergency control valves
Position, operation, access and labelling of the ECV, and what to do when it's wrong.
Draft1 artefact - 4.3
Domestic gas meters
Primary and secondary meters, diaphragm and electronic meters, and how to identify them.
Draft1 artefact - 4.4
Meter regulators: how they work and how to check them
How a regulator holds outlet pressure steady, what lock-up means, and how regulators fail.
Draft1 artefact - 4.5
Meter installation, housings and positioning
Where meters can go, meter housings, and the components of a complete installation.
