Use this quick guide for urgent leaks, sewer backups, gas odors, water-heater failures, and overflowing fixtures. If water is near electricity, the ceiling is bulging, or anyone is in danger, leave the area and call 911.
For a whole-home leak, look for the main shutoff where the water line enters the property, near the meter, in a garage, crawlspace, utility room, or exterior wall. Turn the valve clockwise until it stops. If it will not move, do not force it.
For a fixture leak, use the small angle-stop valve on the wall or floor beneath the sink, toilet, or appliance. Close both hot and cold valves when applicable.
Move people and pets away from wastewater, standing water, damaged ceilings, and electrical equipment. If safe, place containers under a leak and remove valuables from the area. Do not touch wet electrical devices or enter contaminated water.
Protecting the area gives the technician a safer starting point and can reduce damage while help is on the way.
Tell us the city, service address, best callback number, what failed, whether water is still flowing, and whether sewage, gas odor, or electricity is involved. Photos or a short video can help after the area is safe.
Clear details help us prioritize active risk and prepare the right equipment for the first visit.
Call for ASAP supportThese steps are for temporary stabilization only. Do not attempt a repair involving gas, electrical systems, pressurized equipment, sewage contamination, or structural damage.
For a leaking tank, close the cold-water supply valve above the heater if it is safe to reach. Turn off gas or electrical power only if you know the correct shutoff and can do so safely. Never relight a heater after a gas odor.
Close the valve on the wall behind or beside the toilet, then stop flushing. If the bowl is rising, remove the tank lid and lift the float only if you can do so without contact with contaminated water. Call for recurring overflows or sewage backup.
Close the hot and cold angle stops beneath the sink. If the supply hose or valve is broken and water continues, use the main shutoff. Remove stored items and keep water away from outlets and appliances.
Stop using sinks, toilets, showers, washers, and dishwashers. Keep children and pets away, avoid contact, and do not pour chemical drain cleaner into a backed-up line. Call for professional diagnosis and cleanup guidance.
