What is a Plumbing Emergency?

Signs that require immediate professional help and when you can wait for regular service.

Water damage from plumbing emergency

Published: January 12, 2026 | Reading time: 7 minutes

Not every plumbing problem needs a 2 a.m. phone call. Some do. The difference usually comes down to one question: is it causing damage or a hazard right now, and will it be worse by morning?

A Simple Test

Ask yourself three things. Is water or sewage moving into places it should not be? Is there a gas smell or a health hazard? Will waiting a few hours cost you a lot more? One yes means treat it as an emergency. All no means you can shut things off and book a normal appointment.

True Emergencies

Burst or fast-leaking pipe

Water through a ceiling, a spraying supply line, or a meter that spins with everything off. Shut off the main at the meter box near the street or the valve where the line enters the house. Our guide on shutting off water in an emergency shows how, and signs of a burst pipe in a wall covers leaks you cannot see.

Sewage backing up

If wastewater is coming up through a tub, shower or floor drain, stop using water in the house. Several fixtures backing up together points at the main sewer line, often tree roots in an older clay or cast iron lateral. Check for a capped cleanout pipe in the yard near the house and look at whether it is full. Tell the plumber what you see. See why drains back up in Lawrenceville homes.

Gas smell

Leave the house, leave the door open if you can do so safely, do not flip switches, and call from outside. Natural gas in Lawrenceville city limits comes from the City of Lawrenceville, so the gas utility is a separate call. A plumber handles gas piping inside the house, such as a gas line leak, after the utility has made it safe.

No water at all

Check with a neighbor. If the whole street is dry, it is a utility issue and Gwinnett County Water Resources is the number to call. If only your house is dry, it could be a broken service line, a frozen pipe or a closed valve.

Overflowing toilet that will not stop

Close the valve behind the toilet. If it does not stop, or the water is dirty, treat it as a sewage problem.

Leaking water heater

Water from the tank itself means the heater is failing. Shut off the cold valve on top, cut power or gas, and see what to do when a water heater leaks.

Problems That Can Usually Wait

  • One slow drain. Plunge it, and book a visit. See how to unclog a drain.
  • A dripping faucet. Put a bowl under it and schedule a fix.
  • A running toilet. Close the valve behind it until it is repaired.
  • Low pressure at one tap, which is usually an aerator or cartridge.
  • No hot water in warm weather, unless the heater is leaking.

FAQ: Plumbing Emergencies

What counts as a plumbing emergency?

Anything that is actively damaging the house or making it unsafe: a burst pipe, sewage coming up indoors, the smell of gas, water coming through a ceiling, a leaking water heater tank, or no water at all. If it is getting worse while you watch, treat it as an emergency.

Is a clogged drain a plumbing emergency?

Usually not, if it is one fixture and everything else works. It becomes urgent when sewage comes up indoors, several fixtures back up together, or it is the only working bathroom in the house.

Is no hot water an emergency?

Usually it can wait until morning. Treat it as urgent in a freeze, or when a baby or an elderly person is in the house. If the heater is leaking from the tank, shut off the water to it and call right away.

What should I do while I wait for a plumber?

Close the main shutoff at the meter box or where the line enters the house, switch off power to any wet area, move belongings, and take photos. If you smell gas, leave the house first and call from outside.

What should I tell the plumber when I call?

Where the water or smell is, when it started, what you have already shut off, and your address. Ask for the price before any work starts, and ask the plumber to confirm their Georgia license number.
