This is required to protect the pump and piping against any type of line blockage including the inadvertent closing of an isolation valve. Such a condition will cause immediate pump breakage or other system failures. Liquiflo manufactures two sizes of Relief Valves in 316 SS and Alloy-C. 10 ft. 2 ft.
