Daily pressure variations are normal in municipal water systems, especially during peak usage times like morning and evening when most people are using water simultaneously. However, extreme variations often indicate regulator problems or issues with your home’s plumbing system.
A properly functioning pressure regulator should smooth out these variations, maintaining consistent pressure regardless of what’s happening with the municipal supply. If you’re experiencing significant pressure swings, your regulator may not be responding correctly to system changes.
Other causes include partially closed valves, mineral buildup in pipes, or problems with the municipal water main. A professional pressure test can determine whether the issue is with your regulator, your home’s plumbing, or the municipal supply.
