A tank that fails sends clean supply water across the floor, and the water keeps coming until the supply valve to the heater is closed. Wall bottoms, baseboards and any ceiling below soak up the rest, so the damage depends on where the heater stands.
From tank water to a dry room
The crew confirms the heater's power or fuel supply is off, runs water extraction with wands, and moves boxes and furniture off the wet floor. Baseboards come off and small openings at the wall bottoms let air reach the wet cavity while dehumidifiers pull moisture from the room.
- The supply valve and the power or fuel are shut off first
- Contents are lifted off the wet floor
- Baseboards are removed so air reaches the wall bottoms
- A ceiling below is checked for water from a heater upstairs
