A plumbing emergency is any problem causing active damage or a safety hazard that cannot wait — a burst pipe or active flooding, a sewage backup, no water in the home, an overflowing toilet you cannot stop, or a leaking water heater. The smell of gas is a life-safety emergency: leave and call your gas utility or 911 immediately. Problems that are contained and not causing damage — a slow drip, one slow drain, a running toilet — usually are not emergencies and can wait for a scheduled visit.
Knowing whether you have a true emergency helps you decide between calling a costly after-hours plumber now or waiting for a cheaper scheduled visit. The dividing line is damage and safety: is water actively harming your home, or is there a safety hazard?
Clear emergencies include a burst pipe spraying water, flooding you cannot stop, a sewage backup (a health hazard, not just a mess), a complete loss of water to the home, and a water heater that is leaking or failing. In all of these, every hour of delay means more damage or more risk, which justifies the emergency call.
The most serious is gas. If you smell gas (often described as rotten eggs) or suspect a gas leak, this is not a wait-for-the-plumber situation — leave the building immediately, do not flip switches, and call your gas utility or 911 from outside. Gas work in NYC must be handled by a Licensed Master Plumber, but safety comes first.
On the other side, many annoying problems are not emergencies. A faucet that drips, a single slow-draining sink, or a toilet that runs wastes water and should be fixed, but if you can contain it (or shut off that fixture’s valve), it can usually wait for a normal appointment — saving you the premium emergency rate.

Is a slow drain a plumbing emergency?
Usually not. A single slow drain or a drip is annoying but contained, and can typically wait for a scheduled visit. Active flooding, sewage backups, and no water are the real emergencies.
What should I do if I smell gas?
Treat it as a life-safety emergency: leave immediately, don't flip switches, and call your gas utility or 911 from outside. Do not wait for a plumber to address a suspected gas leak.
Is an overflowing toilet an emergency?
If you can't stop it and it's overflowing onto the floor, yes — shut off the toilet's valve (usually behind or below it) to stop the water, then call. If contained, it can often wait.
