Immediate actions
Immediate actions
- Compare hot and cold flow at several outlets to understand the affected branch.
- Check for drafts, open windows, unheated cabinets, basement penetrations, and exposed piping from a safe location.
- Do not force a frozen valve or use a flame, torch, or improvised high heat.
- Arrange observation during thawing and keep the correct private shutoff accessible.
What changes the response
What changes the response
Boston and BWSC cold-weather guidance says never use an open flame to thaw a pipe. Before warming any area, identify the relevant water control and consider where water will go if a split pipe begins flowing. Keep combustion, electrical, and space-heater risks out of the response.
Questions before the handoff
Questions before the handoff
- Which segment is suspected and what evidence supports that location?
- Can safe ambient heat reach it without opening or damaging material?
- Who will watch for leakage as flow returns?
- Afterward, what insulation, draft, or recurring-freeze condition needs a separate correction?
