PUT ACCESS AND WATER CONTROL TOGETHER
A private inlet valve may sit immediately beside a building riser, yet the two have different owners and different rules for isolation. Water at a cupboard threshold can also travel away from its source before it becomes visible.
Record which apartment loses flow, where the cupboard is and who can authorise entry. The plumber should test the private branch first where practical and refer work on the riser to the building controller.
