Plumbing Emergency: What to Do (and Who to Call) Right Now
A plumbing emergency is any water, drain, or gas failure that can flood your home, expose you to sewage, or cut off running water, and it needs action in seconds, not hours. Your first move is almost always the same: shut off the water, make the area safe, then call the right help. This page tells you which situations qualify, what can wait, and exactly who to phone.
What counts as a plumbing emergency (and what can wait)?
A plumbing emergency threatens your property, your health, or your access to water: a burst pipe, a sewage backup, a gas smell, or no water at all. Problems that only waste water or annoy you, like a dripping faucet or one slow drain, can usually wait for a scheduled visit. The test is simple: damage, danger, or loss of a basic function.
Water you cannot stop is the clearest emergency. A single burst supply line can push out several hundred gallons an hour and soak drywall, flooring, and framing fast. Sewage and gas move the situation past property damage into a health and safety hazard, which changes who you call and how quickly.
If none of those apply, and you can shut off the one fixture involved and still use the rest of the house, you almost certainly have a next-day repair, not a 2 a.m. call. Slow drains, a running toilet, and a drippy faucet all sit in that group.
Emergency or can it wait? A plumbing triage table
Use this table to triage fast. Find your situation, confirm whether it is a true emergency, take the first move listed, then call the right number. It covers the calls that come in most: burst pipes, no water, sewage backups, gas odor, overflowing toilets, and water heater leaks. When in doubt, treat any water you cannot stop as an emergency.
| Situation | Emergency or can wait? | Your first move | Who to call |
|---|---|---|---|
| Burst or badly leaking pipe | Emergency | Shut off the main water valve | Emergency plumber |
| No water at any tap | Emergency (check the street first) | Check the main valve and meter; ask neighbors | Water utility if the street is dry, plumber if only you are |
| Sewage backing up into tubs or drains | Emergency (health hazard) | Stop running all water; stay off every drain | Emergency plumber; utility if the public main is blocked |
| Gas or rotten-egg smell near a water heater or line | Emergency (danger) | Leave the house; no switches, no flames | 911 and the gas utility, from outside |
| Overflowing toilet | Emergency if it will not stop | Close the shutoff behind the toilet | Plumber if it keeps rising or it is your only toilet |
| Water heater leaking from the tank | Emergency | Close the cold-water valve; turn the unit off | Emergency plumber |
| No hot water in freezing weather | Urgent | Check the pilot or breaker; protect pipes from freezing | Plumber, same day |
| Dripping faucet or running toilet | Can wait | Note it; close the fixture stop if needed | Plumber, next scheduled visit |
| One slow drain, second bathroom available | Can wait | Try a plunger; keep off it | Plumber, non-emergency booking |
What to do first in any plumbing emergency
The first five moves are the same for most emergencies, and the order matters. Stop the water, remove the danger, limit the damage, build your insurance record, then get the right help on the phone. Work top to bottom and skip a step only when it clearly does not apply to your situation.
- Shut off the water. Close the stop valve at the leaking fixture, or the main shutoff where the line enters the house, to stop the flow at the source.
- Kill power or gas if needed. If water is near outlets, cords, or the electrical panel, cut power at the breaker. If you smell gas, do not touch switches; leave and call from outside.
- Contain the water. Use towels, buckets, and a wet vacuum, move belongings and electronics clear, and open a lower faucet to drain pressure from the affected pipe.
- Document the damage. Photograph and video everything before cleanup. A dated record supports a homeowners insurance claim for sudden, accidental water damage.
- Call the right pro. Reach an emergency plumber for pipes and fixtures, the gas utility or 911 for gas, and your water utility for a suspected street-side main break.
How do I shut off the water?
Every fixture has a small stop valve on the supply line: turn it clockwise to close it. For a whole-house leak, find the main shutoff where the service line enters, often near the water heater, in a basement, or in a ground box by the street, and close it. Our guide on how to shut off the water to your house shows where each valve hides.
The most common plumbing emergencies and your first move
These are the failures that fill after-hours schedules. Each one has a specific first move that buys time until a plumber arrives, and knowing it can be the difference between a mop-up and a gutted room. Match your situation below, act, then call.
Burst pipe. Shut the main water valve, drain the line through a low faucet, and cut power if water is near electrics. A frozen pipe that has split will only gush once it thaws, so keep the main off. See what to do when a pipe bursts for the full first-ten-minutes checklist.
No water anywhere. Ask neighbors first. If the whole street is dry, a public water main break is on the utility to fix. If only your home has none, check the main valve, a frozen line, or the pressure regulator; a failed buried water service line repair between the meter and the house is the homeowner’s cost and often needs same-day work.
Sewage backing up. Stop using every sink, toilet, shower, and washer at once, since more water only pushes more waste into the home. Keep people and pets away from the contaminated area. Raw sewage carries bacteria, so this is a health call as much as a plumbing one; read sewage backing up into the home for cleanup and prevention.
Gas or rotten-egg smell. Leave the house immediately. Do not flip switches, light a flame, or start a car in the garage, and do not use a phone inside. From a safe distance outside, call 911 and your gas utility’s emergency line. This outranks any water issue.
Overflowing toilet. Close the shutoff valve on the wall behind the toilet, or lift the tank lid and push the flapper down to stop the flow. If it keeps rising or several drains gurgle together, the blockage may be in the main line, not the toilet.
Leaking water heater. Close the cold-water valve on top of the tank and switch the unit off, gas control to off or the electric breaker down, so it cannot run dry and overheat. A tank leaking from the body is usually failed and needs replacement, not a repair.
Who should you call: 911, the utility, or a plumber?
The right number depends on the hazard and on who owns the pipe. Gas and any risk to life go to 911 and the gas utility. A street-side water problem goes to the water utility. Failures inside your home or on your side of the meter go to an emergency plumber. Calling the wrong one wastes the minutes that matter.
- 911 and the gas utility: any gas smell, water pouring into an electrical panel, or a person in danger. Call from outside.
- Your water utility: no water across the street, a geyser in the road, or sewage where the public main is the likely blockage. Curb-to-house lines are usually the homeowner’s, though this varies by city.
- An emergency plumber: burst pipes, fixture and water heater failures, and blockages on your side of the meter. Confirm the after-hours rate before they roll a truck.
What does an emergency plumber cost?
Emergency and after-hours plumbing costs more than a scheduled visit, and the premium is the price of speed. Expect roughly $100 to $350 per hour in 2026, against about $80 to $130 for standard daytime work, plus a trip or call-out fee in many areas. Big jobs like a burst pipe or main-line clog run higher.
| Charge | Typical 2026 range | Notes |
|---|---|---|
| After-hours hourly rate | $100 to $350 | Standard daytime is often $80 to $130 |
| Trip or call-out fee | $150 to $250 | Added for non-business hours in many markets |
| Typical emergency visit | $150 to $500 | Simple repairs and clears |
| Complex job (burst pipe, main line) | $500 to $2,000 | Depends on access and damage |
Timing drives the multiplier. A weeknight call may run about 1.5 times the normal rate, while weekends and holidays often land at 2 to 3 times standard pricing, depending on your area and the company. Ask for the after-hours rate and the trip fee up front, and get the diagnosis before you approve the repair.
One more reason to act fast: most homeowners policies cover sudden, accidental water damage but exclude damage from a slow leak you left alone. Shutting the water off quickly and photographing the scene protects both your home and your claim.
Frequently asked questions
What is considered a plumbing emergency?
A plumbing emergency is any failure that can damage your home, threaten health, or cut off water: a burst or leaking pipe, sewage backing up, a gas smell, an overflowing toilet, a leaking water heater, or no water at all. A dripping faucet, a running toilet, or one slow drain is not an emergency and can wait for a scheduled visit.
What should I do first in a plumbing emergency?
Shut off the water first, either at the fixture’s stop valve or the main shutoff where the line enters the house. If water is near outlets or the panel, cut the power. If you smell gas, leave and call from outside. Then contain the water with towels and buckets, photograph the damage for insurance, and call the right pro.
Is a clogged toilet a plumbing emergency?
Usually not, if you have a second working bathroom and the bowl is not overflowing. Stop flushing, close the shutoff behind the toilet, and clear it or book a plumber for the next day. It becomes an emergency when it is your only toilet, when it overflows onto the floor, or when several drains back up at once, which points to a main-line problem.
Is no water a plumbing emergency?
It can be. First check whether neighbors also lost water, which points to a water main break the utility must fix. If only your home is dry, look for a closed main valve, a frozen line, or a failed pressure regulator. A broken buried service line between the meter and the house is your responsibility and often needs same-day repair.
Do emergency plumbers cost more?
Yes. Emergency and after-hours plumbing often runs $100 to $350 per hour in 2026, against roughly $80 to $130 for standard daytime service, plus a $150 to $250 trip or call-out fee in many areas. Weeknight calls may cost about 1.5 times the normal rate, and weekends or holidays often run 2 to 3 times. A typical visit lands between $150 and $500.
Should I turn off my water heater in an emergency?
Often yes. If the water heater is leaking, or you have shut off the main water supply, turn the heater off so it does not run dry and overheat. For a gas unit, set the control to off or pilot; for electric, switch off its breaker. Then close the cold-water valve on top of the tank.
