Emergency Plumbing: What to Do Before the Plumber Arrives

emergency water damage plumbing tips

Plumbing emergencies don’t wait for convenient times. A burst pipe at 2 AM or a sewage backup during a holiday dinner requires immediate action. Knowing what to do in those first crucial minutes can save you thousands in water damage.

Step 1: Shut Off the Water

The most important thing you can do is stop the water flow.

For localized leaks:

  • Look for a shutoff valve near the fixture
  • Toilets have a valve behind or beside the base
  • Sinks have valves under the cabinet
  • Turn clockwise to close

For major leaks or burst pipes:

  • Go to your main water shutoff valve
  • Usually located near the water meter or where the main line enters your home
  • Turn clockwise until fully closed
  • Know where this is BEFORE an emergency

Step 2: Turn Off Your Water Heater

If you’ve shut off the main water supply, turn off your water heater to prevent damage:

  • Gas water heaters: Turn the gas valve to “pilot” or “off”
  • Electric water heaters: Switch off the breaker

Running a water heater without water can damage the tank or heating elements.

Step 3: Address Electrical Hazards

Water and electricity are a dangerous combination:

  • If water is near electrical outlets, switch off power at the breaker
  • Don’t touch electrical appliances while standing in water
  • If you can’t safely reach the breaker, call your utility company

Step 4: Document the Damage

For insurance purposes, document everything:

  • Take photos and videos of the damage
  • Note the time the emergency started
  • Keep track of what actions you took
  • Save receipts for any emergency supplies

Step 5: Minimize Water Damage

While waiting for the plumber:

  • Mop up standing water - The longer water sits, the more damage it causes
  • Move valuables - Get furniture, electronics, and important documents to dry areas
  • Open cabinets - Let air circulate under sinks and in vanities
  • Use fans - Increase air circulation to help drying
  • Don’t use a vacuum - Regular vacuums aren’t designed for water

Common Plumbing Emergencies

Burst Pipes

Often caused by freezing, corrosion, or pressure issues. Shut off main water immediately.

Overflowing Toilet

Turn off the valve behind the toilet. Don’t flush again. Use towels to contain water.

Sewage Backup

Don’t use any water in your home. This is a health hazard—keep family and pets away from affected areas.

Gas Leak (Water Heater)

If you smell gas, leave immediately. Don’t use light switches or phones inside. Call your gas company from outside.

Major Leak Under Slab

You might notice warm spots on floors, the sound of running water, or unusually high water bills. Shut off main water and call immediately.

When to Call for Emergency Service

Call for emergency plumbing when:

  • You can’t stop the water flow
  • Sewage is backing up into your home
  • You smell gas
  • Water is near electrical systems
  • Flooding is occurring

Prevent Emergencies

Many emergencies are preventable with regular maintenance:

  • Annual plumbing inspections
  • Water heater maintenance
  • Drain cleaning before clogs become backups
  • Pipe insulation in winter
  • Knowing where your shutoff valves are
