Emergency Plumbing Tips: What to Do Before the Plumber Arrives

Stay Calm and Act Fast

Plumbing emergencies feel chaotic, but the steps you take in the first 10 minutes make a massive difference in how much damage occurs. This guide covers the most common plumbing emergencies New Jersey homeowners face — and exactly what to do before the plumber arrives.

Step 1: Shut Off the Water Supply

This is the single most important thing you can do. Find and turn off the water supply before anything else.

• For a specific fixture (toilet, sink, washing machine): Look for the shutoff valve on the supply line behind or below the fixture. Turn it clockwise until it stops.
• For the whole house: Your main water shutoff is usually near the water meter — often in the basement, crawl space, or outside near the foundation. Turn it clockwise to shut off all water to the home.

Every adult in your household should know where the main shutoff valve is before an emergency happens.

Burst Pipe

1. Shut off the main water supply immediately
2. Open faucets to drain remaining water from the pipes
3. Turn off your water heater (electric: flip the breaker; gas: turn the dial to "pilot")
4. Move valuables, electronics, and furniture away from the affected area
5. Place buckets and towels to contain water
6. Do NOT turn the water back on until the pipe is repaired

Overflowing Toilet

1. Remove the tank lid and push the flapper down manually to stop water from entering the bowl
2. Turn off the shutoff valve at the base of the toilet (turn clockwise)
3. Do NOT flush again — this will worsen the overflow
4. If the floor is wet, lay down towels to absorb water and prevent slipping
5. Call a plumber — repeated toilet overflow often signals a main sewer blockage

Sewage Backup

1. Stop using all water in the home immediately
2. Do not enter flooded areas — raw sewage contains serious pathogens
3. Keep children and pets away from the affected areas
4. Open windows to ventilate if sewer gas smell is present
5. Document all damage with photos for insurance purposes
6. Call an emergency drain cleaning service — this is not a DIY situation

Water Heater Failure

1. Turn off the cold water supply to the heater (valve on the cold water inlet pipe)
2. For gas heaters: turn the gas valve to the "off" or "pilot" position
3. For electric heaters: shut off the circuit breaker
4. If the tank is actively leaking: connect a garden hose to the drain valve and route water to a floor drain or outside
5. Do not attempt to repair a gas water heater yourself — call a licensed plumber

When to Seek Urgent Plumbing Help
