When should you call an emergency water heater pro in Ventura?
Call for urgent help, and leave the house first where noted, if any of these apply:
- You smell gas (a rotten-egg odor) near the water heater: leave right away without flipping switches, then call 911 or SoCalGas from outside.
- A carbon monoxide alarm sounds, or you see soot, scorch marks, or flames outside the burner area: get everyone outside and call 911.
- The tank is actively leaking or water is spreading toward walls, flooring, or electrical outlets. Shut off the cold-water valve above the tank.
- The temperature and pressure relief valve is discharging hot water repeatedly, or the tank is making loud banging sounds.
- Water from the hot tap is scalding hot, or steam comes out of faucets.
- There is no hot water and someone at home needs it for medical or caregiving reasons.
If you smell gas or a carbon monoxide alarm goes off, leave the building first and call 911 or SoCalGas from outside. Don't wait for a plumber.
