Maintenance Tips

• Inspect Anode Rod: Check the sacrificial anode rod after the first 6 months and then annually; replace when heavily corroded to prevent internal tank corrosion.

• Test T&P Relief Valve: Lift the temperature & pressure relief (T&P) valve once a year to ensure proper pressure relief and safety.

• Check for Leaks & Corrosion: Periodically inspect around water connections, drain valve, fittings, and vent piping for leaks or corrosion; address promptly.

• Clean Exterior & Vent: Wipe the exterior to keep it free of dust; verify proper venting and clear obstructions to maintain combustion efficiency and safe exhaust.

• Monitor Temperature Setting: Keep thermostat at recommended ~120 °F to balance comfort, energy savings, and reduce scaling.
