we were called out to address ongoing water, pressure and volume issues at the customers residence. The customer had previously had a pressure reducing valve and water filters installed by another technician after about a month the water pressure and flow had significantly worsened affecting fixture performance, upon evaluation We identified that the root cause was related to the 1 inch PRV installed outside. We replaced the PRV after approval from hoa,tested the system and confirmed that everything is now functioning as intended with no further issues.
