5 Signs You're Dealing with a Plumbing Emergency

Some plumbing emergencies are easy to spot. If you wake up at 2 a.m. with water around your ankles, we're pretty sure you'll be on the phone instead of googling warning signs. Others are more subtle: a water heater making a strange noise, a drain gurgling after dinner or a faint sewer smell in the basement. Knowing when these signs point to a real emergency, and when they can wait, protects your home, your health and your wallet.

The Insurance Information Institute reports that water damage and freezing claims averaged $15,400 per claim from 2019 to 2023, and they make up about 1 in 4 homeowners property damage claims. The longer water sits, the more it soaks into drywall, floors and insulation, and the bigger the bill gets.

So here's the rule of thumb: if a problem is causing damage to your property, putting your health at risk or leaving you without water, it's an emergency, and it'll only get worse if you wait. Below are 5 signs to help you spot one:

1. Water You Can't Shut Off

A burst pipe, a split supply line or a fitting that gives way can release a lot of water in minutes. If water is spraying, pouring or pooling and you can't stop it at the fixture, it's a plumbing emergency.

Start by shutting off your main water valve. In most homes it's in the basement or utility area, near where the water line comes through the wall, often by the water meter. Turn it clockwise until it stops.

Then call a plumber. Shutting off the water stops the flow, but the pipe still needs to be repaired and the area needs to dry. The EPA recommends drying water-damaged areas within 24 to 48 hours to prevent mold, so the clock starts as soon as the water hits the floor.

Pipes rarely burst out of nowhere. Freezing, high water pressure, corrosion and age are common causes. Here's more on what causes pipes to burst.

2. Is Sewage Backing Up Into More Than One Drain?

Yes, sewage backing up into more than one drain is a plumbing emergency. When toilets, tubs and floor drains back up at the same time, the problem is usually a blockage in your main sewer line. Every flush or load of laundry can push more wastewater into your home, so stop using water and call a plumber.

One slow sink is usually just a local clog. The real warning sign is when the backup is system-wide and several fixtures act up together. Watch for:

• Water coming up in the tub or shower when you flush the toilet.
• Gurgling sounds from drains or toilets.
• Water or sewage coming up through a basement floor drain.
• A sewage smell that hangs around near drains.

All of these point to a blocked main sewer line. Tree roots, grease, "flushable" wipes and older pipes that have cracked or sagged are common causes.

A backup isn't just messy. According to the Virginia Department of Health, sewage carries bacteria, viruses and other germs that can cause stomach illness and skin infections. Keep kids and pets away from the area, and never touch sewage with bare hands.

Until help arrives, stop using water. Chemical drain cleaners won't clear a main line blockage, and they make the water dangerous for anyone who has to work in it.

3. Is a Sewer or Gas Smell an Emergency?

Yes, both can be. A strong sewer smell that won't go away needs a plumber quickly. A natural gas smell is more serious: leave the house first, then call your gas utility or 911 from outside. Both can smell like rotten eggs, so if you're not sure which one it is, treat it as gas.

If it's sewer gas. The Illinois Department of Public Health points to drains with dry traps as a common way for sewer gas to get into homes. A trap is the curved pipe under a drain that holds water to block gas from the sewer.

Start with a quick check. Run water for a minute in drains you rarely use, like a basement floor drain or a guest bathroom shower. If the smell fades, a dry trap was likely the cause. If it comes back or stays strong, call a plumber. It could be a cracked pipe, a bad seal or a blocked vent.

Don't just live with it. IDPH notes that lower exposure can irritate your eyes and throat, and longer exposure may cause headaches, fatigue and dizziness.

If it's natural gas. This is the one time a plumber isn't your first call. Ready Illinois advises:

• Don't try to find the leak.
• Don't light anything or use light switches, phones or other electronics inside.
• Open windows and doors only if it's quick and easy.
• Get everyone out, pets included.
• Once you're somewhere you can't smell gas, call your gas utility. Call 911 if there's immediate danger.

Once the utility has made the home safe, a licensed plumber can repair or replace the damaged gas line.

4. Frozen Pipes or No Water at All

If you turn on a faucet in winter and get nothing, or just a trickle, a pipe has probably frozen. That alone is a problem, but the bigger risk comes next. Ice expands inside the pipe, and a pipe that cracks while frozen can start leaking the moment it thaws.

Frozen pipes are one of the most expensive winter problems a homeowner can face. State Farm paid more than $628 million in frozen pipe claims from 2024 through mid-2025, with an average claim of more than $30,000. Illinois topped the list of states with the highest claim costs.

If the pipe you suspect is easy to reach, the American Red Cross suggests:

• Keep the faucet open so water can flow as the ice melts.
• Warm the pipe gently with a hair dryer, a heating pad or towels soaked in hot water.
• Never use a blowtorch, propane heater or any other open flame.
• Check your other faucets, since more than one pipe may be frozen.

Call a plumber if you can't find the frozen section, can't reach it or can't thaw it. Call right away if you see water, bulging or cracks once it starts to thaw.

No water in warmer months is a different story. Check with a neighbor or your water utility first, since it could be a main break or planned work on the street. If it's only your home, call a plumber. You can't cook, clean or flush without water, and the cause could be a failed valve or a leak in your service line.

5. A Leaking, Hissing or Rumbling Water Heater

A water heater holds gallons of very hot water under pressure. When something goes wrong, it can flood a basement or, in rare cases, fail in a dangerous way. These are the signs to act on:

• Water pooling around the base. If the tank itself is leaking, it's usually failing and can't be repaired. The leak will only get worse.
• Water or steam coming from the relief valve pipe. The temperature and pressure (T&P) relief valve is a safety part that opens when the tank gets too hot or the pressure gets too high. According to This Old House, it opens at 210°F or 150 psi to keep the tank from bursting. If it's discharging, something in the system needs attention. Never cap or plug that pipe.
• Hissing or popping on a gas water heater, along with a gas smell. Treat it as a gas leak and follow the steps in sign 3.
• No hot water along with a leak or a burning smell. Shut the unit down and call for help.

If you see a leak, follow these water heater shutdown steps: turn off the power or gas, then close the cold water supply valve on top of the tank.

A rumbling or popping sound on its own is usually sediment built up at the bottom of the tank. It's not an emergency, but it's a sign the heater needs to be flushed or checked soon.

What Should You Do in a Plumbing Emergency While You Wait?

In a plumbing emergency, stop the water first, then make the area safe. Shut off the main water valve or the fixture's supply valve, keep away from water near electricity, and stop using your drains. Then move valuables, take photos for insurance, and keep kids and pets out until the plumber arrives.

Here's a quick checklist:

• Stop the source. Close the shutoff valve under the sink or behind the toilet. If you can't find one, or it doesn't work, close the main water valve.
• Stay safe around electricity. The Virginia Department of Health advises turning off power if there's standing water or wiring may be wet, but only if you can reach the breaker from a dry spot.
• Stop using water. Don't flush, run the dishwasher or do laundry until the problem is fixed.
• Skip the chemical drain cleaners. They rarely fix serious clogs and can damage pipes.
• Move what you can. Get rugs, boxes, electronics and furniture out of the wet area.
• Soak up clean water. Towels, a mop or a wet/dry vacuum help slow the damage. Leave sewage to the pros.
• Document everything. Take photos and videos before cleanup, and call your insurance company. Some insurers can help arrange cleanup.

Which Plumbing Problems Can Wait for a Scheduled Visit?

Problems that aren't causing damage, a health risk or a loss of water can usually wait for a scheduled visit. That includes one slow drain, a dripping faucet, a running toilet, low pressure at a single fixture or a water bill that's crept up. Book them soon, though. Small problems tend to grow.

One slow drain or an occasional clog. If just one sink or toilet is slow, the clog is likely in that fixture's line, not the main sewer. If several drains slow down together, go back to sign 2.

A dripping faucet or running toilet. These aren't urgent, but they add up. The EPA says a faucet dripping once per second wastes more than 3,000 gallons a year, and the average home's leaks waste more than 9,300 gallons a year.

Low water pressure at one fixture. This is often a clogged aerator or showerhead. If the pressure drops suddenly across the whole house, call sooner, since it can point to a leak.

A higher water bill with no clear cause. This often means a hidden leak, sometimes in a spot you can't see. Here's how to tell if you have a water leak underground. Schedule a visit before the leak causes damage.
