Why pipes freeze on the South Shore
Arctic air behind a nor'easter or a clear winter night can drop temperatures far below freezing for days. Older homes often run supply pipe along the rim joist where the basement meets the outside wall, through kitchen walls on the exterior and into unheated garages and porches. Cold air slipping in at the sill or a basement window is what freezes the pipe.
- The pipe usually splits during the freeze but leaks when it thaws.
- Pipe near the rim joist, in outside walls and in garages freezes first.
- Sealing drafts, insulating exposed pipe and keeping the heat on prevents most freezes.
If a pipe has already frozen and split, see frozen pipe cleanup and basement water damage. The National Weather Service Boston office posts cold weather warnings for the area.
Should outside hose bibs be shut off for winter?
Yes. Closing the inside valve and draining the bib keeps water out of the part of the pipe that sits in the cold wall.
Does a dripping faucet really help?
A slow drip keeps water moving and relieves pressure in the pipe, which lowers the chance of a split on the coldest nights.
What should I do if a pipe is already frozen?
Open the faucet, warm the pipe gently with a hair dryer or space heater kept away from anything flammable, and never use an open flame. If it has split, close the main and call.
Why do pipes along the rim joist freeze so often?
The rim joist is the thin wall between the basement and the outside air, and drafts at the sill reach pipe running along it.
Can the freeze check promise a pipe will not freeze?
No. It sorts the common risk factors so you know what to do before a cold night. It is planning information only.
