Why does a water heater leak cause so much damage?
Because a tank holds a large volume and releases it all at once when it fails. The water spreads over the floor and runs under cabinets and along walls before it stops.
A water heater can hold a substantial volume of water, and a failed tank or a failed valve releases it over a short time. In a garage or a laundry room the water runs toward the lowest point, which may be a floor drain, a wall or a corner. A slab floor holds water along its edges and under the base of cabinets, and the drying is planned around those edges rather than around the open floor.
Does a washer leak need a full cleanup?
Usually yes, when water has run under the cabinets or into the floor covering. A small splash on a hard floor may need only a wipe, but a leak that ran for a while needs readings.
A washer that leaks over an hour or two can soak the floor covering, the cabinet base and the wall behind it, and the water may have run under the surface before it was seen. The crew reads the floor and the wall to judge the spread. A short leak on a sealed hard floor can be cleaned and dried in a day, but a longer leak needs the covering lifted and the base cut out.
What should the homeowner do before the cleanup?
Shut off the supply valve and the appliance's power if it is safe, move items out of the wet area, and photograph the water and the appliance before anything is touched.
The supply valve is usually behind or beside the appliance, and closing it stops the flow. For a water heater, the power or gas supply should be turned off by the homeowner only if it can be done safely and the manufacturer's instructions allow it. Photographs of the pooled water, the base of the appliance and any label on it are the record the homeowner will need. Call the line on (833) 490-5225, which is answered 24/7.
Can the floor be dried in place?
Sometimes. Hard flooring and slab edges that were wet for a short time can dry in place. Carpet, pad and soaked cabinet bases usually need removal.
Drying in place depends on the material and the time the water sat. A vinyl plank floor that has lifted at a seam may need the planks lifted and dried, and it may be possible to reset them. Carpet pad that has taken water is removed, because it holds moisture against the slab. Cabinet bases that have swollen are cut out, since the particleboard will not return to its shape.
Who repairs the appliance?
The trade or the manufacturer's service the homeowner chooses. The water work does not repair or replace the appliance, and the record the crew keeps is for that repair.
A licensed plumber or appliance technician is the right trade for the connection, and a homeowner should keep the record of the leak with the appliance's details. A water heater that has failed at its base usually needs replacing rather than repairing, and that decision is for the plumber. The water work is separate, and its record shows the trade where the water was and how far it travelled.
