Lochinvar & A.O. Smith 100276814 Relief Valve
The Lochinvar & A.O. Smith 100276814 Relief Valve is a critical safety component designed for high-demand commercial and residential water heating systems. This 1" 150# T&P Relief Valve is engineered to automatically discharge water if internal tank conditions exceed 150 PSI or 210°F, preventing catastrophic vessel failure. As a direct replacement for 100167360, this OEM part ensures precise fitment and maintains the original engineering specifications of your Lochinvar boiler or A.O. Smith water heater. Fabricated with a heavy-duty brass body and a corrosion-resistant internal probe, it provides reliable over-pressure protection in harsh hydronic environments. For technicians performing HVAC system maintenance, swapping out a scaled or leaking T&P valve with this factory-authorized 100276814 replacement part is the standard procedure to ensure code compliance and operational safety.
Key Benefits- OEM Compatibility: Seamlessly serves as the direct replacement for 100167360, eliminating the need for field piping modifications.
- Dual-Safety Function: Provides simultaneous temperature and pressure relief (150 PSI / 210°F) to protect the integrity of the pressure vessel.
- High-Flow Capacity: Features a 1-inch NPT connection to handle the discharge requirements of large-scale commercial water heaters.
- Durable Construction: Built with high-grade brass to resist mineral buildup and mechanical sticking over long service cycles.
How do I know if my 100276814 valve needs replacement?
If you notice consistent dripping from the discharge line, it often indicates the seat is fouled by scale or the spring has weakened. A valve that fails to open during a manual lever test must be replaced immediately to ensure vessel safety.
Is this compatible with other Lochinvar models?
This specific T&P relief valve is a standard component across many Lochinvar and A.O. Smith platforms. Always verify the BTU rating on the original valve tag matches the 100276814 specifications before installation.
Can I use a 3/4" valve if my port is 1"?
No. You should never bush down a temperature and pressure relief valve. Reducing the inlet size restricts the BTU relief capacity and violates most mechanical codes. Use this 1-inch valve for 1-inch tapped tanks.
