Call Immediately — Plumbing Emergencies
Burst water pipes actively flooding your home — turn off the water at the meter and call. Gas leaks — get out of the building and call from outside. Sewage backing up through drains or toilets — stop using water and call. These are health and safety issues, not jobs to Google solutions for.
Orange sits at 900 metres elevation, giving it cold winters and significant temperature swings that cause pipe expansion and contraction throughout the year. Winter in Orange produces burst pipe events when exposed pipes freeze overnight. If you wake up to burst pipes, the priority is water off at the meter, then call.
