Low Water Pressure in Your Home? Here’s What It Means

Low water pressure can be more than a nuisance — it often signals a hidden issue.

Here are the most common causes we see in Northern Virginia.

1. Clogged Aerators or Showerheads

Mineral buildup from hard water restricts flow.

Fix:
Unscrew and clean with vinegar.

2. Partially Closed Shutoff Valves

Check your home’s:

• Main shutoff valve

• Fixture shutoff valves

Both should be fully open.

3. Pressure Regulator Failure

Your pressure regulator controls water entering your home.
If it fails, water pressure will drop suddenly.

4. Leaking or Corroded Pipes

Older homes in Leesburg, Purcellville, and Sterling are especially prone to this.

Warning:
Hidden leaks can cause mold or foundation issues.

5. Municipal Water Supply Problems

Sometimes the issue isn’t inside your home at all.
