Low Water Pressure: Causes, Fixes, and When to Call a Plumber

Why Is My Water Pressure So Low?

Low water pressure is a frustratingly common complaint from homeowners throughout Walton, Morgan, Clarke, and Jasper Counties. Sometimes the fix is simple — but other times it signals a serious underlying plumbing issue that needs professional attention.

Common Causes of Low Water Pressure

• Clogged aerator: The small screen on your faucet collects mineral deposits over time. Cleaning or replacing it often restores full pressure instantly.
• Partially closed shut-off valve: Check that the main shut-off and meter valve are both fully open.
• Pressure regulator failure: Most homes have a pressure regulating valve (PRV). When it fails, pressure drops throughout the whole house.
• Hidden pipe leak: A leak in your water supply line bleeds off pressure before it reaches your fixtures — and can cause significant water damage if undetected.
• Corroded or scaled pipes: Older galvanized pipes develop mineral buildup on the inside walls, restricting flow over time.
• Municipal supply issues: Occasionally, the problem is with your water provider's main line, not your home's plumbing.

Is Low Pressure Affecting the Whole House or Just One Fixture?

This is the key diagnostic question. If pressure is low at just one faucet or shower, the fix is usually localized — a clogged aerator or showerhead. If pressure is low throughout the entire home, you likely have a PRV issue, a main line leak, or pipe corrosion — all of which require a licensed plumber.
