Lochinvar & A.O. Smith 100110605 Valve

When you are dealing with high-pressure systems, the Lochinvar & A.O. Smith 100110605 Valve is a critical safety component designed for rigorous field performance. This 3/4" T&P relief valve is engineered to meet the demanding specifications of commercial and residential water heaters, rated for 150 PSI and a 105,000 BTU discharge capacity. As a veteran technician, you know that maintaining the thermal and pressure envelope is non-negotiable; this genuine OEM repair part ensures that the system triggers a relief cycle at exactly 210°F (99°C) or when internal pressure reaches the 150# limit. Its heavy-duty brass construction and 1-inch probe depth make it a direct-drop replacement for AO Smith water heater parts and Lochinvar boilers, eliminating the guesswork of universal fitments that often fail under high-limit safety valve requirements.

• Precise 150 PSI Set Point: Engineered for absolute accuracy in high-pressure environments to prevent tank rupture.
• 105,000 BTU Rating: Sufficient steam-gas relief capacity for a wide range of Lochinvar and A.O. Smith units.
• Direct OEM Compatibility: Replaces part number 100110605 exactly, ensuring consistent thread engagement and probe depth.
• Industrial-Grade Brass Body: Resists corrosion and mineral buildup, maintaining long-term reliability in hard water conditions.

• Can this valve be used on any brand? While it uses a standard 3/4" NPT connection, it is specifically calibrated for the venting requirements of Lochinvar & A.O. Smith equipment. Always verify your unit's BTU rating against the 105,000 BTU plate on this valve.
• How often should I test the relief lever? We recommend following the manufacturer's maintenance schedule, typically an annual lift-test to ensure the seat isn't seized, preserving the temperature and pressure relief function.
• Is the 150# rating suitable for all residential tanks? Most residential tanks are tested to 300 PSI but rated for 150 PSI operation. This HVAC safety component is the industry standard for those specifications.
