In 1874 Joseph Watts founded the Watts Regulator Company that made their reputation by "Setting the Standard in Valve Technology." During this time, Watts manufactured pressure reducing valves to regulate steam and relief valves to ensure safe operation of water heaters and boilers. In the 1900's, Watts introduced the revolutionary combination temperature and pressure (T&P) relief valve, a protection device for use on hot water supply tank systems. The T&P valves prevented dangerous hot water heater explosions and continue to be an integral part of today's water heating systems.
