For this job, it was required me to replace a defective PRV that was causing the water pressure to pulsate when multiple fixtures were in use in home. Prior to replacement the water pressure 60 psi which was throwing things off. But the defective valve has been replaced as well as an old gate valve. Two ball valves have been installed on the system all workers document with photos. All items for leaks and no leaks were found. Water pressure after valve replacement was 60 psi and our client is very happy!
