Returned after estimate was approved by customer customer approve installation of dual PRV’s set up consisting of one high-pressure PRV rated for harsher conditions and the secondary standard PRV. The first PRV knocks the incoming pressure from approximately 130 psi down to roughly 90 psi, while the second PRV further reduces pressure from approximately 90 psi down to 60 psi. This configuration extends the service life of the PRV’s and provides improved long-term system protection. We furnish and installed both PRV’s and added a boiler drain between the units to allow isolated pressure testing of the high-pressure PRV. System was pressurized, tested and verified to be operating correctly upon departure.
