Why Your Home's Water Pressure Suddenly Dropped (And What to Do About It)

You turn on the shower and it's barely a trickle. The kitchen faucet sputters. Something's wrong.

Low water pressure is one of the most common calls we get at Meyers Plumbing, especially in homes throughout Moon Township, Imperial, Oakdale, McDonald, and the greater Pittsburgh Airport area. Here's what's usually causing it—and when you need a professional.

Common Culprits Behind Low Water Pressure

Corroded galvanized pipes. Many homes in our area built before 1970 still have original galvanized steel pipes. Over decades, mineral deposits build up inside, narrowing the pipe diameter until water can barely squeeze through. If your pressure has gradually worsened over years, this is likely your issue.

A partially closed main shutoff valve. Check the valve where water enters your home. If it's not fully open, you're throttling your own supply. This happens more than you'd think after repairs or inspections.

Well pump problems. Many properties in Oakdale, McDonald, and surrounding areas rely on well water. A failing pressure tank or worn pump can cause sudden pressure drops. If you're on a well and notice the pressure fluctuating, your system likely needs attention.

A failing pressure regulator. Homes with pressure regulators can experience sudden drops when the regulator fails. These typically last 10-15 years.

Hidden leaks. A major leak somewhere in your system diverts water before it reaches your fixtures. Signs include unexplained spikes in your water bill or damp spots in your yard.

When to Call a Plumber

If the pressure drop is sudden and affects your whole house, or if you've ruled out simple fixes like the shutoff valve, it's time for a professional diagnosis. Pipe corrosion and hidden leaks only get worse—and more expensive—with time.
