Notice the signs
Observe
Record the pipe location, material if known, water temperature, first sound, rooms below, visible spray direction, and whether a private building master stopped the flow. Preserve a view of the failed section before disposal if access is already safe.
Protect the room
Safety line
Move people away from sagging finishes and wet power. Never use an open flame on a frozen line, climb into an unstable wet cavity, or operate the meter, curb control, or other department hardware.
Material note
Local boundary
If the suspected break lies near the service boundary, use address records and Cohasset Water interpretation before assigning the segment. A wet patch or pressure change alone cannot establish public or customer responsibility.
Service flow
Written scope
Ask the repair scope to name isolation, access, length and material, fittings, temporary versus permanent status, pressure test, freeze exposure, debris, drying referral, and finish closure. Hidden deterioration beyond the agreed endpoints needs a change process.
Close the loop
Verification
Keep the repaired area accessible until the stated test is complete. Confirm that valves are returned to their intended positions, fixtures receive normal flow, no connection weeps, and any opened assembly is labeled for later restoration.
