Under this condition,pressure cannot build <br /> up in the piping system When a nozzle is opened, a poppet in the STP-MLD moves to a position <br /> that restricts the flow to 2 GPM.This is the indication to the operator that a leak is:present if there <br /> are no leaks,pressure rapidly builds in the system forcing the STP-MLD to open to the full-flow <br /> position. In a system with no leaks,it takes approximately three seconds fora complete test. No <br /> further line testing takes place until the line pressure drops significantly below the normal static <br /> system pressure. <br /> 4113/04 <br /> 8l 39t/d 210D"1-A Hl aid F.F.bf.AQbFR7.
