Gas PRV Problem - A large new project had issues with gas boilers and package AHUs shutting off due to erratic gas pressure. Incoming pressure was steady at 2 in. WC, while downstream pressure fluctuated from 0 to 12 in. MSC technicians found that the installed pressure reducing valve was unsuitable for the system and successfully replaced it with the correct PRV.
