Quick answer
What this service involves
Tankless water heaters heat water on demand and do not store a large tank of hot water. They still have water inlet and outlet connections, service/isolation valves, internal heat-exchanger passages and, on some models, a condensate drain. Water below a wall-mounted unit may originate inside the appliance or from external piping above it.

Service considerations
What can affect the repair decision?
Leak source
Water from a replaceable fitting or valve is different from water escaping through a tank shell or internal component.
Equipment type
Gas, electric, tankless and indirect systems have different parts, access needs and safety procedures.
Condition and scope
Age, corrosion, parts availability, installation requirements and the extent of water damage may affect the provider’s recommendation.
Questions before you call
Tankless Water Heater Leak Repair FAQs
Can a tankless water heater leak even though it has no storage tank?
Yes. Tankless systems still contain water passages, fittings, valves and sometimes condensate components that can leak.
Is water from a tankless heater always a water leak?
Not necessarily. Condensing models produce condensate that drains away through a dedicated line. A technician can distinguish normal condensate from a failed connection or component.
Can a tankless heat exchanger be repaired?
The answer depends on model, warranty, leak location, parts availability and the extent of damage. A qualified technician should assess the unit before a repair decision.
