How to do it
- Find the confirmed heater manual and the relief-valve manufacturer label. Keep the exact operation check separate from a full qualified valve inspection.
- Give those instructions and the last service record to a qualified water-heater professional. Mention leakage, blocked or missing discharge piping, and conflicting instructions.
- Have the professional assess the discharge route and perform the applicable operation check safely. Never block or cap a relief-valve outlet.
- Record the completed check. If full-inspection intervals conflict, obtain the applicable manufacturer or professional guidance rather than choosing an interval yourself.
Stop and get help when
- Dripping or leaking valve
- Missing, obstructed, or unsafe discharge pipe
- Unusual temperature or pressure
Have a qualified water-heater professional perform relief-valve checks and resolve label or manual conflicts.
