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
