WebAir pressure relief valves are used for operational requirements, and they gently release the pressure before it hits the maximum high-pressure point and circulates it back into the system. How often should I test air pressure relief valves? Pressure relief valves should be subject to an annual test, one per year. WebMar 14, 2014 · A typical developer-built, high-rise building will have a single or duplex booster pump in the basement. The pump serves the entire building with pressure reducing valves on all of the lower floors where the supply pressure will exceed 80 psi.
