Step 1: Is anyone in danger?
- IfYou smell gas or hear hissing from a gas lineThenLeave the house now. Call 911 or SoCalGas from outside. Stop here.
- IfWater is in contact with outlets, lights or the electrical panelThenKeep everyone out of the area. Turn off power only from a dry spot. Then continue.
- IfSewage is in a living areaThenKeep children, pets and anyone with health concerns away. Then continue.
Step 2: Can you stop it?
- IfClosing a fixture valve stops the leak completelyThenLeave it closed. A regular daytime visit is usually fine.
- IfClosing the main stops it and the household can manage without waterThenOften fine until morning. Call first thing.
- IfClosing the main does not stop itThenEmergency. Use the meter box valve if you can and call for help now.
- IfSewage keeps rising even with no water in useThenEmergency. The line or the city sewer may be blocked.
Step 3: What can the household live without?
- IfThe only toilet does not workThenUsually worth calling tonight.
- IfNo hot water, but no leak or gas smellThenUsually next day, unless someone needs hot water for medical reasons.
- IfOne slow sink or a dripping faucetThenRegular visit.

Why waiting is sometimes the better choice
Once water is stopped and no one is at risk, daytime appointments can give you more choice of licensed contractors and more time to compare written quotes. That matters most for larger repairs.
Waiting is not the right choice when damage is ongoing. Water that keeps spreading, sewage that keeps rising and anything involving gas cannot wait.
Common questions
What if I am not sure where the water is coming from?
Close the main. If the leak stops, you have time to think. If it does not, treat it as urgent.
Is a small sewage backup that has stopped an emergency?
Not always, as long as no one uses water and the area is kept clear. Call early the next day and keep drains unused.
