The Emergency Plumbing Checklist

Every plumbing emergency gets worse by the minute, and the homeowners who come through them cheaply all knew the same short list in advance: where the shutoffs are, the first move for each of the five common emergencies, and which problems can honestly wait until morning. This article is that list. Read it once, walk your house once, and tape the shutoff locations inside a kitchen cabinet. When water is spraying at 2 AM, you will not want to be learning any of this for the first time.

Where are your shutoffs, and do they work?

Shutoff knowledge is the whole game. Find these four today, not during the emergency.

• Main water shutoff. In most Puget Sound homes it is where the supply line enters, often in the crawlspace, a garage wall, or a basement. There is also a valve at the meter near the street, which needs a meter key or long screwdriver. Older gate valves seize; turn yours gently once a year to confirm it still moves and still fully stops the water. If it does not, replacing it is a small planned job now versus a useless valve during a burst.
• Fixture shutoffs. Small oval valves under every sink and toilet. These let you kill one fixture without drying out the whole house.
• Water heater valves. A cold-water shutoff on the inlet pipe above the tank, plus the gas valve or the breaker that powers it.
• Gas shutoffs. Each gas appliance has a valve on its supply line. The house main is at the meter and needs a wrench. Know where both are, but leave the meter valve to the utility unless you smell gas and are leaving the house.

What are the five plumbing emergencies and the first move for each?

Memorize the first move. Everything after it can be looked up; the first move cannot wait.

1. Burst pipe. First move: main shutoff, immediately. Then open faucets at the lowest and highest points to drain the lines, kill electricity to any soaked area, and start moving water out. Speed here is measured in gallons: a burst supply line can release hundreds of gallons an hour into your framing. Bursts cluster during hard freezes, and our guide to preventing frozen pipes covers how to avoid being the house it happens to. For the repair itself, that is a job for our pipe repair team.
2. Sewer backup. First move: stop using water everywhere in the house. Every flush and shower load feeds the backup. If sewage is rising through a floor drain or the lowest toilet, especially during heavy rain, the blockage or surcharge is downstream of everything, and no plunger will beat it. Keep people and pets away from the sewage, since this is contaminated water. Diagnosis usually means a camera down the sewer line to find roots, grease, or a collapsed section.
3. Water heater leak. First move: close the cold inlet valve on top of the tank, then shut off the energy source, gas valve to off or the breaker off for electric. A tank leaking from the bottom has usually rusted through and will not be patched. Water dripping onto a gas burner or electric elements is also a hazard beyond the flooding. Our water heater team can tell you honestly whether it is a fitting repair or a replacement.
4. Gas smell near a gas water heater. First move: do not touch any switch, phone, or appliance. Leave the house, take everyone with you, and call your gas utility from outside. A rotten-egg odor means the added odorant is doing its job. If it is safe to do so on your way out, turn the appliance gas valve off, but never linger in a house that smells like gas, and never hunt for the leak yourself. After the utility clears the home, a licensed gas line professional should find and fix the source before the appliance runs again.
5. No water at all. First move: check whether it is just you. Look at the meter valve, ask a neighbor, and check for utility work outside. If neighbors have water and you do not, look for a closed valve, a failed pressure regulator, or, during a freeze, an ice plug in your supply line. No water is the least dangerous emergency on this list, but during a hard freeze it is often the first symptom of a pipe about to burst, so treat it with urgency in cold weather.

What should you have on hand before anything goes wrong?

A small kit, stored where you can find it in the dark, covers nearly every first move above.

• A working flashlight or headlamp near the main shutoff.
• A meter key or long flathead screwdriver if your only reliable valve is at the street.
• An adjustable wrench and a pair of channel-lock pliers.
• A quality plunger and a hand auger for ordinary clogs.
• A wet/dry vacuum, old towels, and a couple of buckets.
• Pipe repair tape or a rubber-and-clamp patch kit, strictly as a temporary measure to slow a pinhole leak until the plumber arrives.
• Your plumber's number saved in your phone, plus the tag on the water heater with its age and model, which speeds up every service call.

Which problems can honestly wait until morning?

Not everything that feels urgent at 10 PM is an emergency, and after-hours service costs more everywhere. Honest triage:

• Can wait: a dripping faucet, one slow drain, a running toilet you can stop by closing its fixture valve, a clogged toilet in a house with a second bathroom, low pressure at a single fixture.
• Cannot wait: water you cannot stop, sewage coming up, any gas smell, a leak reaching electrical outlets or the panel, no water during a hard freeze, or a leaking water heater you cannot isolate.

The dividing line is control. If a shutoff valve has contained the problem and nothing is actively flooding, burning, or contaminating, you can sleep and book the repair for daylight rates. If you cannot contain it, call now. Our emergency dispatch team handles the cannot-wait list, and our after-hours repair service covers the problems that surface outside a normal workday. Real people answer early and late, 6 AM to 6 PM every day.

Common questions

How fast does a burst pipe actually flood a house?

Faster than people expect. A typical half-inch supply line under normal pressure can release several gallons per minute, which means hundreds of gallons per hour soaking into subfloor and drywall. That is why the main shutoff is the first move and why knowing its location beats every tool in the kit.

Should I try to fix a burst pipe myself?

Stopping the water, draining the lines, and slowing a leak with a clamp patch are all good homeowner moves. The permanent repair belongs to a licensed plumber, both because Washington requires licensing for plumbing work and because a burst usually has a cause, freeze exposure, corrosion, or pressure problems, that will produce the next burst if nobody addresses it.

My water heater is leaking a little from a valve. Emergency or not?

A drip from the temperature and pressure relief valve or a fitting, with the tank isolated by its shutoff, can usually wait for a daytime appointment. Water seeping from the tank body or pooling underneath means the tank itself is failing, and with gas or electric energy still connected it should be shut down the same day.

Who do I call first for a gas smell: the plumber or the utility?

The utility, always, from outside the house. Gas utilities respond to leak calls urgently and at no charge, and they will make the scene safe. The licensed repair of the leaking line or appliance connection comes after, and that is where a plumbing and gas contractor takes over.
