Hose bib
A hose bib that drips in January is a freeze file until proven otherwise.
Exterior taps and their interior stops are a regular winter failure. Occupants who leave a hose attached give ice a place to form.
Disconnect hoses before deep cold.
A hose left on the tap can trap water and split the bib or the interior pipe.
Use the interior stop, not the handle in the ice.
Forcing a frozen exterior handle can break it open. The interior valve is the isolation.
Water in the parkade under a bib is a clue.
Follow the frost. Do not assume the only damage is at the chrome handle.
Questions people ask
Can I pour hot water on the tap?
Do not. You can crack the fitting and scald yourself. Isolate inside and call.
Is this a suite problem or a building problem?
Some bibs are unit; some are common. The manager should say which, after the water is stopped.
