Top 5 Plumbing Emergencies in Oakville and How to Handle Them Fast


Plumbing emergencies don’t follow a schedule—they hit when you least expect them. Whether it’s a burst pipe on a freezing Oakville night or a toilet that overflows during a family gathering, one thing is certain: acting fast can prevent costly damage. As a licensed plumbing company serving Oakville for years, we’ve responded to hundreds of emergency calls. This guide covers the top 5 plumbing emergencies we see in local homes—and what to do before professional help arrives.



1. Burst Pipes

Why It Happens: Most common during Oakville’s winter months, burst pipes occur when water inside freezes, expands, and cracks the pipe.

Signs:

  • Sudden water pressure drop
  • Water stains on ceilings or walls
  • Puddles or flooding

What to Do:

  • Shut off your home’s main water supply immediately
  • Open nearby taps to release pressure
  • Call a licensed plumber for emergency repairs

Prevent It:

  • Insulate exposed pipes
  • Keep your home above 10°C in winter
  • Let faucets drip during extreme cold spells



2. Main Drain Backup

Why It Happens: Tree roots, grease buildup, or collapsed old pipes cause sewage to flow back into your home.

Signs:

  • Multiple drains backing up
  • Gurgling toilets
  • Sewage smell in the basement

What to Do:

  • Stop using all water fixtures
  • Avoid chemical drain cleaners
  • Call an emergency drain expert immediately

Prevent It:

  • Schedule yearly camera inspections
  • Never flush wipes or pour grease down the drain



3. Toilet Overflow

Why It Happens: A clogged toilet or a malfunctioning float mechanism leads to water spilling over the bowl.

Signs:

  • Rising water level after a flush
  • Water pouring onto the bathroom floor

What to Do:

  • Turn off the toilet’s water shut-off valve (behind the toilet)
  • Use a plunger to clear the blockage
  • If unsuccessful, call a plumber to avoid further damage

Prevent It:

  • Avoid flushing non-flushables (wipes, paper towels, etc.)
  • Teach kids proper toilet use



4. Water Heater Failure

Why It Happens: Sediment buildup, thermostat failure, or a broken heating element can leave you without hot water.

Signs:

  • No hot water from taps
  • Popping or rumbling noises from the tank
  • Water leaks around the heater

What to Do:

  • Shut off the water and power supply to the heater
  • Don’t attempt DIY repairs—it may void warranty
  • Call a licensed plumber for diagnosis

Prevent It:

  • Flush the tank once a year
  • Have regular inspections



5. Frozen Pipes

Why It Happens: Oakville winters can freeze pipes in unheated areas like garages, attics, or exterior walls.

Signs:

  • No water flow from taps
  • Frost on visible pipe sections

What to Do:

  • Turn off the main water supply if you suspect a freeze
  • Try warming the pipe slowly with a hair dryer (never use open flames)
  • Call a plumber before it bursts

Prevent It:

  • Wrap pipes in heat tape or foam
  • Keep cabinets open to allow warm air around pipes
  • Insulate crawlspaces
