Diagnose pulsating water noise
Two days ago I started hearing what sounded like dripping water. It is constant at about 1 second intervals. The sound is traveling through the water pipes as it can be heard in our bathrooms and kitchen. I can feel the vibration in the cold water line but not the hot. I have tried shutting off the valves at the toilets and sinks one at a time but that doesn't seem to resolve the problem. The water also is pulsating. Could this be a PRV problem. It sure has me baffled. Any help would be appreciated!
