Learn about the top plumbing emergencies and what to do quickly to limit damage, with simple steps homeowners can take before calling a plumber.
Plumbing emergencies don’t wait for a convenient time. They show up late at night, during a snowstorm, or right before guests arrive.
The good news? A lot of damage can be reduced—or even avoided—if you know what to do in the first few minutes.
Here are five of the most common plumbing emergencies we see in Milton and Halton Region, and what you should do right away.
1. Burst Pipes
A burst pipe can release a lot of water fast. This is one of the most serious plumbing emergencies because it can cause major damage in minutes.
What to do immediately:
- Shut off your main water valve
- Open nearby faucets to drain remaining water
- Turn off your water heater (if safe to do so)
- Move valuables away from the area
If this happens in winter, freezing is often the cause. Even a small crack can turn into a full burst once things thaw.
👉 Pro tip: If you’ve had freezing issues before, this is something worth addressing before next winter.
2. Sewer Backup
This is one of the worst ones to deal with. If water (or worse) is coming up through drains, you’re likely dealing with a sewer backup.
Warning signs:
- Multiple drains backing up at once
- Gurgling sounds from toilets or sinks
- Water pooling around basement floor drains
What to do:
- Stop using all water in the house
- Keep people and pets away from affected areas
- Call a plumber right away
This isn’t something you want to DIY. It’s a health risk and can get worse quickly.
3. No Hot Water
Not always an “emergency” in the damage sense—but definitely feels like one.
Common causes:
- Water heater failure
- Pilot light out (gas systems)
- Sediment buildup in the tank
What to check:
- Is the unit getting power?
- Has the breaker tripped?
- Is the pilot light out?
If your tank is older, this could be a sign it’s nearing the end of its life.
4. Overflowing Toilet
It happens more often than people think—and it escalates fast.
What to do right away:
- Turn off the water valve behind the toilet
- Remove the tank lid and push the flapper down if needed
- Use a plunger to try clearing the blockage
If plunging doesn’t fix it, the issue may be deeper in the drain line.
5. Major Leaks
Not all leaks are dramatic—but even a steady leak can cause serious damage over time.
Signs to watch for:
- Water stains on ceilings or walls
- Musty smells
- Unexpected spikes in your water bill
What to do:
- Shut off the water supply to the affected fixture
- Contain the leak as best you can
- Call for help before it spreads
