Tell the provider what is happening
Report the fuel or electrical type, model, leak rate, water location, and replacement timing. Mention water near wiring, outlets, lights, or another floor.
A. O. Smith's leak guidance calls for shutting down power or fuel and water as appropriate to the equipment. Actual controls and safe access need confirmation for your installation. A. O. Smith leaking-heater guidance.
Do not cross standing water or approach wet electrical equipment to reach a switch. If access is unsafe, have emergency responders or a qualified electrician handle electrical isolation.
Ask who will confirm the heater is safely out of service. Do not restart it with uncertain water level or unresolved damage.
Protect access and the house
Keep people away from the wet area. Move dry belongings only where you can do so without approaching hazards. Ask an appropriate restoration professional about water removal, drying, and affected building materials.
Do not plug a safety-valve discharge or improvise a drain connection. The equipment provider should specify any appropriate temporary containment and its limits.
Arrange safe access for removal and installation. Tell the installer about stairs, narrow doors, finished surfaces, and any continuing water damage.
Resolve essential hot-water needs
Plan another location for essential bathing or washing if the wait makes that necessary. Keep a workable arrangement for children or anyone who needs assistance.
Do not run the damaged heater for one more shower without qualified operating direction. Ask for a realistic next scheduling step and what should trigger emergency help rather than waiting.
Make the replacement scope complete
Confirm exact equipment, removal, installation corrections, related trade work, permits, and restart verification. Separate equipment replacement from drying and building repair.
Your next step is to contact the replacement provider with the active-leak details and request an immediate, equipment-specific waiting plan. The plan should name who isolates the heater, who handles damage, and how your household manages until completion.
