Route active hazards and tank failure. A gas odor, carbon-monoxide alarm, smoke, electrical damage, uncontrolled hot-water discharge, severe corrosion, or active tank leak needs the appropriate emergency or repair path. An anode booking form is not an emergency channel and an anode cannot repair a failed tank.
Identify the exact heater. Collect label details, tank or tankless type, fuel or power, age, location, connections, access above the unit, water treatment, service history, current symptoms, warranty, and visible condition. Keep customer observations separate from a confirmed diagnosis.
Check serviceability and authority. Use the model manual, parts list, technical bulletin, and warranty terms to confirm an anode exists, can be serviced, and has an approved replacement path. Do not generalize one manufacturer's interval or procedure to every tank.
Inspect before prescribing. State whether the appointment includes removal and inspection, what happens if removal risks damage, what condition is documented, and how the replacement recommendation is made. Explain the authorization point before added labor, specialty extraction, or a larger repair.
Match the part and access plan. Identify compatible part number or specification, material, dimensions, thread, clearance, segmented or other access solution if approved, powered-anode dependencies, and adjacent connections that may affect work. Avoid promising odor correction without diagnosing all plausible sources.
Make the quote complete. Separate service or diagnostic fee, anode, labor, access, limited draining, specialty removal, adjacent repairs, permit or correction items if applicable, taxes, warranty, exclusions, and change approval. State what happens if the tank condition makes continued work unreasonable.
Hand off a safe, documented result. Record the model, removed-part condition, replacement part, installation evidence, refill and air-purge completion, leak check, restart status, applicable settings, cleanup, warranty, maintenance guidance, and any corrosion, valve, venting, electrical, drain, or tank issue referred for further work.
