Make the area safe
Water and electricity are isolated when appropriate, and occupants are kept away from unsafe ceilings or contaminated water.
An active plumbing leak should be controlled first, then diagnosed. Shut off the nearest safe valve or the main water supply when necessary, protect people and electrical equipment, contain water if possible, and avoid opening walls or ceilings until the source and hazards are better understood.
Water and electricity are isolated when appropriate, and occupants are kept away from unsafe ceilings or contaminated water.
The closest reliable shutoff or main valve is used, with temporary containment when safe.
Accessible piping, valves, fixtures, pressure, and surrounding damage are evaluated.
The approved repair is completed, water is restored gradually, and the system is checked for additional leakage.
Label it and keep access clear before an emergency occurs.
A failed local shutoff may require the main supply to be closed.
Water extraction, structural drying, mold prevention, and finish restoration may require a restoration contractor.
Documentation can help with insurance and repair planning.
Shut off water if safe, protect valuables, avoid electrical hazards, and provide access to the leak and main valve.
Sometimes as an emergency measure, but suitability depends on pipe material, location, pressure, and damage.
Age, corrosion, pressure, movement, freezing, poor installation, or material failure can contribute.
Usually plumbing access and pipe repair are separate from finish restoration unless specifically included.
