What Qualifies as a Plumbing Emergency?
Not all plumbing problems require a 2 AM service call. Burst pipes, sewage backups, and gas leaks — those are genuine emergencies. A leaky faucet at midnight? Save your money and schedule a regular visit.
Your immediate first step in a real plumbing emergency is locate and shut off your main water valve. It's usually located near the street-facing wall of your basement or crawl space. Turning this off stops the damage from getting worse while you find a plumber.
How Emergency Plumbing Works
An emergency plumber will generally be at your door within 60 minutes. They'll assess the situation before starting work — a good plumber explains what's wrong before touching anything.
Qualified techs carry specialized equipment like pipe cameras, hydro-jetting machines, and commercial-grade pumps. This specialized gear is factored into the premium pricing.
