Respond to a leak alarm
Keep clear of standing water where electrical equipment may be affected.
Identify the affected area, note the asset ID and check whether automatic isolation has stopped the flow.
Do not force a valve or repeat-reset a device. Call the 24 hour line if the source is unclear, access is unsafe or isolation has not occurred.

Isolation hierarchy
Use the authorised local-then-riser sequence. A resident may reopen only their own flat valve, and only once the cause is cleared and the area is dry, and must not force an actuator or override lever.
A building operator or competent responder confirms the local state before considering the riser route.
Do not operate the incoming main without competent direction after local and riser routes have been exhausted.

Safe shutdown
Building operator or competent responder only. Confirm the affected location, asset serial and paired project record before acting.
Observe the indication and valve state. Stop if access is unsafe, a valve resists, the source is unknown or electrical equipment may be affected.
Success means flow has stopped in the affected area and the isolated state is recorded.

Restart and return to service
Restart only after the cause is cleared, the area is dry, electrical risk is absent and competent authority has confirmed the route.
Open only the authorised project valve and observe the affected area. Stop after any repeat alarm and escalate.
Record the asset serial, isolation state and measured result before return to service.

Handover checks
The client checks the current issue, outstanding limitations, maintenance evidence and responsible party at handover and after each revision.
