Frozen pipes in Thornbury? Here's what to do.
Frozen pipes are a winter emergency — every minute matters because frozen water expands and bursts the pipe. Acting in the first 30 minutes can prevent flood damage.
Try this first
Safe steps you can take in the next 10 minutes — in order.
- 1Turn off the internal stopcock immediately to limit damage if the pipe has burst.
- 2Open all taps so any thaw can flow rather than building pressure.
- 3Apply gentle warmth — hairdryer, warm towels, hot-water bottles. NEVER use a naked flame or boiling water.
- 4Start at the end of the pipe nearest the tap and work back toward the frozen section.
When to stop and call
If the pipe has already burst, if you can't access the frozen section, or if the boiler is locked out and the condensate pipe is frozen and won't defrost gently.
Likely causes
Most cases of frozen pipes in Thornbury homes come down to one of these.
- External condensate pipe on combi boilers (most common)
- Loft pipework with no insulation
- Pipework on external walls in unheated rooms
- Outside taps with no isolation valve
