Plumbers do a wide variety of jobs, not just unclogging drains and repairing broken sink fixtures. Anything from installing a new water heater to doing gas line work is a job for a qualified plumber. Many of these jobs can be scheduled in advance because they aren’t urgent enough for an emergency response, but not all. Some plumbing problems require professional attention immediately, and a delay can mean the problem has a chance to get much worse.
If any of these four things occur in your home, you have a plumbing emergency on your hands, and you need a plumber ASAP.
