Ruud SP20303A Gas Water Heater Thermostat/Gas Valve Assembly

Ruud SP20303A Gas Water Heater Thermostat/Gas Valve Assembly

The Ruud SP20303A is an OEM replacement thermostat/gas valve assembly engineered for gas-fired water heater applications. This combination control governs gas flow to the burner while regulating water temperature at the tank, making it a direct-fit service part for plumbing and mechanical contractors performing water heater repair and maintenance. As a factory-branded component, the SP20303A is intended for technicians who need a reliable, matched control valve when servicing residential or light commercial gas water heater installations. Because it combines thermostatic temperature control and gas shutoff in a single assembly, it replaces two functions with one part, reducing the number of components a technician needs to source and install during a service call. The SP20303A is stocked for contractors who prioritize manufacturer-matched parts over generic aftermarket substitutes when restoring a gas water heater to proper working order.
