General Notes and Precautions
• Routine service activities for pumpsets are in addition to the requirements listed in the tables for sprinkler systems and hydrant systems as appropriate
• Where multiple pumps supply fire protection systems, only one pump shall be rendered inoperative at any time
• Prior to commencing any preventive maintenance activity all automatic start devices, both local and remote, shall be checked to ensure they are isolated and tagged or locked out.

Item 2.2: Water supply stop valves and isolating valves
OPERATE (two full turns) all water supply stop valves (including backflow prevention stop valves and underground key-operated valves except where owned by the water supply authority) and verify they are fully open, secure in the open position (relaxed ¼ turn if appropriate) and are correctly labelled as indicated on the valve list.
CommentTesting of underground key-operated valves owned by the water supply authority may be difficult to achieve at time of undertaking 6 monthly service. It may be necessary to record this activity as a non-conformance at time of service and develop procedures to co-ordinate and document the results of the test with the local water supply authority.
