SMITH 100108279 is a temperature and pressure (T and P) relief valve designed as a direct replacement component for residential water heater installations. Commonly referenced under model designation TP-100, this valve provides the critical safety function of releasing excess pressure or dangerously high temperatures from the water heater tank. It features a 0.625-inch shank length for proper fitment. Installation is handled by licensed plumbers during new installations, warranty service calls, or routine safety-component replacements on residential water heating systems.\u003c\/p\u003e\n\u003cp\u003eThis T and P relief valve is rated for residential applications and fits most standard gas and electric water heater models. It is not compatible with direct vent water heater configurations. The 0.625-inch shank makes it suitable for tank openings sized to that specification. Replacement of a T and P relief valve is a common service task performed when valves show signs of weeping, corrosion, sediment buildup, or failure to reseat after a pressure event.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTemperature and pressure relief valve provides essential overpressure and overtemperature protection for residential water heaters\u003c\/li\u003e\n  \u003cli\u003e0.625-inch shank length fits standard residential tank port openings on most gas and electric models\u003c\/li\u003e\n  \u003cli\u003eOEM replacement part, model TP-100, designed to restore factory safety performance\u003c\/li\u003e\n  \u003cli\u003eNot suitable for direct vent water heater models\u003c\/li\u003e\n  \u003cli\u003eCompact design supports straightforward swap-out service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eFits most A.O.

Shut off the water supply and disconnect power or gas to the water heater before beginning service. Never plug or cap a T and P valve port or install a valve with a lower BTU\/h or pressure rating than specified on the water heater data plate. After installation, verify the discharge line is routed to a safe drain location and the valve seats properly with no leaks under normal operating pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Temperature and Pressure Relief Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel\u003c\/strong\u003e: TP-100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential replacement part\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible System Types\u003c\/strong\u003e: Gas and electric water heaters (excludes direct vent models)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: A.O.
