What should I do if my water heater is leaking from the top?
Turn off power or gas, close the cold-water valve on top, and book service. Top leaks often come from flex supply lines, the shutoff valve, or the T&P valve connection. We provide same-day and 24/7 water heater help in Dublin, Livermore, and San Ramon.
- Electric: switch off the breaker. Gas: set the control to Off.
- Close the cold-water shutoff above the tank.
- Dry the top and watch fittings for active drips. Avoid DIY if you smell gas.
