Common Questions:

• Is this valve compatible with other brands? While primarily designed for Lochinvar and A.O. Smith, it may fit other systems requiring a 1" NPT 50 PSI relief valve; however, always verify the BTU rating and specific discharge capacity.
• How often should this relief valve be replaced? Technicians should inspect for leakage or mineral buildup during annual maintenance, as seating surfaces can degrade over time in hard water environments.
• Can I adjust the pressure setting on the 100111922? No, this is a fixed 50# set relief valve. Tampering with the spring tension is a safety violation; if a different PSI is required, you must select the appropriate OEM part number.
