Understand the choices

Repair, replace, or maintain?

The right answer depends on the test results, condition, compatibility, safety, service history, and what you want from the system.

Repair

Often considered when the tank or heat exchanger is sound and a serviceable control or component caused the failure.

Replace

Discussed when the unit leaks, is near the end of practical life, cannot meet demand, or repair is not sensible.

Maintain

Tank and tankless equipment receive different care based on manufacturer guidance, water conditions, and visible condition.
