1. 1Protect the areaRedirect foot traffic around the affected area. If the water is near an electrical panel, receptacle or powered equipment, keep clear and call qualified help before cleanup.
2. 2Find the first wet pointFrom a dry, accessible position, look above the puddle. A leak continuing while a fixture is unused may be on the supply side; a leak appearing only during draining suggests a waste connection. Do not run more water when it would spread damage.
3. 3Identify the serviceCompare the pipe and valve labels with the site valve map. If trained and authorized, use a confirmed accessible domestic fixture stop gently. If it is seized, leaking or unlabeled, leave it for the plumber.
4. 4Contain only when safeA bucket or absorbent pads can catch a small clean-water drip without blocking an exit. Do not treat sewage or water of unknown origin as clean water, and do not place a bucket beneath a sagging ceiling.
5. 5Verify the handoffRecord whether flow stopped, rooms affected and the time isolation occurred. Arrange repair and drying; check adjacent rooms and the floor below through normal safe access.

Record the exact location, observed condition, time, actions taken, person contacted and follow-up owner. Keep unresolved items visible. A completed checklist means the check was performed; it does not automatically mean the equipment passed or is safe.
