Water on the floor does something to people: it freezes them. Homeowners describe standing in a spreading puddle, phone in hand, unsure whether to call, mop, or run for a valve they have never used. The fix for that freeze is a short, ordered list learned before the event — not during it. Print this plumbing emergency checklist and tape it inside the cabinet nearest your main shutoff. The whole plan takes about ten minutes, and the first three steps matter more than everything that follows.
The Universal First Three Steps
Every water emergency starts the same way, whatever the cause.
- Stop the water. For a single fixture — a toilet, a sink, a water heater — use that fixture's shutoff valve. For a burst line, a leak you cannot isolate, or water coming from inside a wall or ceiling, use the main shutoff. Turn it clockwise until it stops. If you have never operated yours, go find it today and confirm it turns; a seized valve is the most common reason this step fails.
- Make the area electrically safe. If water is near outlets, switches, appliances, or the breaker panel, cut power to the affected area — but only if you can reach the panel without standing in water. Never wade into standing water to reach a panel. If you cannot reach it safely, leave the area and wait for help.
- Drain the pressure. With the main valve closed, open the lowest cold faucet in the house, or an outdoor spigot, and let the lines drain. This stops the slow seep that continues after the valve closes and gives you a quieter scene to work in.
Only then do the next steps: contain the water with towels, buckets, and mopping; move furniture, rugs, and valuables out of the wet area; and document everything with photos and video before major cleanup. Photos taken before cleanup help document the damage for insurance, and they cost you two minutes. Cleanup before photos costs you evidence.
If a Pipe Bursts
Follow the three universal steps, then call. While you wait, keep the lowest faucet open so the lines stay drained, and keep mopping and moving valuables. If water is coming through a ceiling, do not poke the bulge to drain it — a controlled release sounds clever and usually ends with a ceiling collapse. Let it be, keep people out from under it, and put a bucket under the drip.
After the immediate crisis, the recovery order matters. Cleaning up after a burst pipe goes: stop the water, document, call your insurer, then dry. Drying fast matters more than drying perfectly in the first hours — standing water feeds mold and swells wood and drywall. A plumber handles the pipe; drying and restoration are separate trades, and your insurer can advise on the order.
If Sewage Backs Up
Sewage is a different emergency with different rules. Stop using every drain, toilet, and water-using appliance in the house — every flush and every load pushes more sewage into the backup. Do not pour drain chemicals into a sewage backup; they will not clear it, and they turn a biological hazard into a chemical one. Keep people and pets out of the affected area, and do not try to mop sewage with household towels you intend to keep.
Ventilate if you can do so without spreading the mess, and call promptly. If the backup is house-wide — several fixtures at once — the problem is usually in the main line or the sewer connection, and it needs professional equipment, not a household plunger. A single fixture backing up while the rest of the house drains normally is more likely a local blockage, but the same stop-using-water rule applies until it is cleared.
If You Smell Gas
A gas smell is not a plumbing call first; it is a leave-first emergency. Do not hunt for the leak, do not flip light switches or start engines, and do not use a phone inside the house. Leave, take everyone and pets with you, and call 911 or your gas utility from outside or from a neighbor's phone once you are safely away. If the odor is strong, do not re-enter for any reason. The rotten-egg smell is an added odorant; some people cannot detect it reliably, so any unexplained dead vegetation over a buried line, hissing near a line or appliance, or physical symptoms that clear when you leave the house should be treated with the same seriousness.
If the Water Simply Stops
No water at all is usually less urgent than a burst, but it still deserves a quick check. Confirm whether it is one fixture or the whole house, and ask a neighbor whether they have water — a neighborhood-wide outage points to the supply, not your pipes. Check that the main valve is fully open and that no one has closed a valve during other work. On a well system, check the breaker and the pressure switch before assuming the pump has failed. If the outage follows a hard freeze, a frozen section may be the cause; leave a faucet open a crack and warm the exposed section gently rather than forcing anything.
While you wait for help, the leak-hunting habit from the EPA WaterSense leak-checking advice is worth knowing: a water meter that moves when no water is being used points to a hidden leak somewhere in the system. That check belongs after the emergency, when the water is back on and the scene is calm.
Quick Answers
What do I do first if a pipe bursts?
Shut off the water at the fixture valve or the main, make the area electrically safe if you can do so without standing in water, then drain pressure from the lowest faucet.
Should I turn off the power?
Yes, if water is near electrics and you can reach the panel without standing in water. If you cannot reach it safely, leave the area and wait.
Should I clean up before taking photos?
No. Photograph and video the damage first, then clean up. Photos taken before cleanup document the damage for insurance.
When do I call 911 instead of a plumber?
Call 911 for a strong gas odor, for any situation where someone is hurt or in danger, or when you cannot leave a dangerous area safely on your own. Call a plumber for water and drain emergencies.
