WHAT TO DO IN CASE OF WATER / SEWER / GAS EMERGENCIES
In a plumbing emergency, immediately shut off the main water valve (usually near the meter or in the basement/garage) to stop flooding, turn off the electricity if water reaches outlets, and call a plumber. If a gas leak is suspected, evacuate immediately and call emergency services, do not operate switches, and do not try to turn off the gas yourself.
Emergency Water Instructions
Locate Main
Shut-Off
Find the main valve, usually near the water meter, basement, or utility area.
Turn Off
Turn the valve clockwise or 90 degrees (for lever-style) until it stops.
Drain Pipes
Open the lowest faucets in the house to drain remaining water.
Water Heater
Turn off the gas/power to the water heater if it is leaking, then close the cold water supply valve to it.

How to Shut off Water in a residential home
Locating the Valve
Look for the main shut-off valve near the water heater, furnace, or where the water main enters the house. Outdoor locations may be in a concrete box near the street.
Types of Valves
- Ball Valve/Lever: Turn 90 degrees (perpendicular to the pipe) to shut off.
- Gate Valve (Round Handle) : Turn clockwise until it stops.
Street-Side (Meter Box)
Remove the lid, locate the valve, and turn it clockwise (usually using a T-shaped water meter key).
Emergency Tips
- If the valve is stiff, do not force it, as it may break.
- After turning off, test the water by turning on a faucet inside the house.
- If you cannot find or operate the valve, contact your city's water department for assistance.
Emergency Gas Instructions (SMELL GAS/HISSING)
Evacuate
Get everyone out immediately, including pets.
No Ignition Sources
Do not turn on lights, use appliances, or use phones inside
Shut Off (Only if Safe)
Use a wrench to turn the valve on the meter 90 degrees to a perpendicular position.
Call 911
Call the gas company or 911 from outside the home.
Emergency Sewer/Drainage Instructions
Stop Water Usage
Immediately stop running water, showering, or using the washing machine to prevent more sewage from backing up.
Identify Backup
If toilets or floor drains bubble, it is a main sewer line clog.
Avoid Contamination
Do not walk through sewage, as it can contain bacteria. Clean and sanitize all affected areas thoroughly once fixed.
Do Not Use Drain Cleaners
Chemicals can damage pipes and may not fix the issue.
