Burst pipe or sudden ceiling leak

Shut off the main water immediately. Then open the lowest cold faucet in the home to relieve pressure and help drain remaining water from the line. If it’s safe, place a bucket under the leak and poke a small drain hole in a bulging ceiling section to control collapse risk.

After the water is stopped, call an emergency plumber for leak location, repair, and guidance on drying/mitigation to help prevent mold.

Overflowing toilet

If the toilet is actively rising, remove the tank lid and push the flapper closed (or lift the float to stop filling). Then close the toilet shutoff valve near the wall (turn clockwise).

If one toilet overflows once, it may be a local clog. If multiple fixtures are backing up, treat it as a main line issue and call for professional drain cleaning.

Water heater leaking

If you see water pooling around the water heater, turn off the power source first (gas control to “off” or the water heater breaker), then shut off the cold-water supply valve feeding the tank. If you ever smell gas, leave the home and contact your gas utility immediately. (waterheatersonly.com)

A small drip at a connection can sometimes be tightened, but a leaking tank often means replacement is the safest long-term fix.

Backed-up kitchen sink, shower, or main drain

Stop using water immediately to prevent overflow. Avoid pouring chemical drain openers—they can damage plumbing components and make professional clearing harder and more hazardous.

For recurring clogs or suspected grease/root intrusion, professional hot water jetting can restore full pipe diameter instead of just punching a small hole through the blockage.

Step 1: Shut off the right valve

Start with the fixture shutoff if the leak is clearly at one location (toilet, sink, ice maker, washing machine). If water is moving fast or the leak source is unclear, go to the main shutoff.

Step 2: Relieve pressure and limit spread

Open one cold faucet at the lowest level of the home. Use towels, buckets, and a wet/dry vac if you have one. If water is near electrical hazards, keep clear and shut power off only if safely accessible.

Step 3: Document quickly (if safe)

Take a few photos for insurance and to help your plumber understand what happened. Then focus on stopping damage—not on troubleshooting for an hour while water sits in walls or flooring.

Step 4: Call for emergency service when any of these are true

Winter freeze risk: what actually helps

When temperatures drop into the low 20s (or colder), pipes in unheated areas—garage walls, crawlspaces, exterior walls—are the most likely to freeze. Practical steps that reduce risk:

Hard water and scale buildup

Mineral scale can shorten water heater life, reduce hot-water performance, and contribute to fixture issues over time. If you’re dealing with recurring spots, stiff valves, or reduced flow, a water softening or filtration solution can help protect your plumbing system long-term. Learn more about options on our Water Softening Systems page.

Silent toilet leaks

A running or silently leaking toilet can waste a surprising amount of water and signal worn internal parts. A quick at-home test: add a few drops of food coloring to the tank, wait about 10 minutes, and check the bowl—if color appears, the flapper is likely leaking. Flush afterward. (epa.gov)

Slow drains that “seem fine” until they’re not

If you’re plunging the same sink every few weeks or noticing gurgling, that’s often a sign of buildup beyond the trap—grease, soap scum, hair, scale, or root intrusion in older lines. Proactive drain cleaning can prevent the weekend backup that turns into a true emergency.

What counts as a plumbing emergency?

Any issue that risks property damage, health hazards, or loss of essential water service: burst pipes, active leaks you can’t stop, sewage backup, no hot water with a leaking heater, or water impacting ceilings/electrical areas.

Should I use chemical drain cleaner during a backup?

It’s usually a bad idea, especially during a major clog or main line backup. Chemical drain cleaners can damage certain plumbing materials and create safety hazards when a technician needs to open the line.

How do I know if I should shut off my main water valve?

Shut off the main when you can’t quickly control the leak at a local shutoff, when multiple fixtures are affected, or when water is spreading into floors, walls, or ceilings.

If my pipes freeze, should I use an open flame to thaw them?

No. Open flame can damage pipes and create a serious fire risk. Safer options include increasing heat in the home, opening cabinet doors, and using gentle heat sources designed for household use. If a pipe is frozen and you’re unsure where, call a plumber to avoid splitting the line.

Can a toilet leak waste a lot of water even if I don’t see it?

Yes. The EPA notes that the average home can waste more than 10,000 gallons of water per year from leaks, and a simple food-coloring tank test can reveal silent toilet leaks. (epa.gov)
