Step-by-step decision tree for burst pipes, flooding, gas smells, and no hot water.
Locate your main shutoff valve — usually near the water meter, in the basement, or under the kitchen sink. Turn it clockwise to close.
With the water off, immediate damage is contained. Now call for emergency repair. While you wait: move valuables, place towels, take photos for insurance, and if the ceiling is bulging — puncture it to release trapped water in a controlled spot.
Call Emergency Plumber NowIf you cannot turn off your main, call your water utility's emergency line — they can shut it off at the curb. Simultaneously call an emergency plumber. Get everyone out of flooded areas to avoid electrical hazards.
Call Emergency Plumber NowThis is a utility issue, not a plumbing problem. Call your water company's outage hotline. Check their website or app for estimated restoration time.
Check if your main shutoff is accidentally closed. Also check for an unpaid water bill. If neither is the issue, you likely have a main line break or frozen pipe. Call a plumber today.
Get a Plumber NowStop all water use immediately. Do not flush toilets or run any fixture. This is a main sewer blockage and is a health emergency. Call a plumber now and keep children away from the affected area.
Emergency Service NowTurn off the cold water supply to the water heater (valve on top). If gas, turn off the gas supply too. This needs immediate replacement — a failed tank can flood the home. Call a plumber now.
Emergency Plumber NowThe pilot light is the #1 cause of no hot water on gas heaters. Open the access panel at the bottom and look for a small flame. If it's out, follow the relight instructions on the unit. If it won't stay lit or you smell gas, call your gas company immediately.

Get a Plumber NowStop all water use. Do not flush. Keep family away from affected areas. Sewage contains harmful bacteria. Call an emergency plumber now and consider calling a water damage restoration company as well.
Emergency Plumber NowCould be a dry p-trap (pour water in floor drains) or a cracked vent pipe. Open windows for ventilation. If the smell is very strong or you feel lightheaded, leave the house — sewer gas contains methane and hydrogen sulfide. Call a plumber.
