Before You Call a Pro, Try These Steps

This checklist helps you determine whether your low water pressure issue is caused by a simple fixable factor or if it requires a licensed technician to diagnose the underlying plumbing problem.

1. Check the Main Shutoff Valve

Make sure the main shutoff valve inside your home is fully open. Even a partially closed valve can cause whole-house pressure loss.

2. Test Multiple Fixtures

Try faucets in different rooms. If the issue only affects one fixture, the problem is usually localized (aerator, cartridge, debris). If it affects the entire house, the cause is deeper in the system.

3. Compare Hot vs. Cold Water

If the hot water only is weak, the issue may be inside the water heater — not the whole plumbing system.

4. Remove & Clean Aerators

Mineral debris often collects in faucet aerators and showerheads. Unscrew, rinse, reinstall — sometimes this alone restores normal pressure.

5. Check For Recent Plumbing Work

After repairs, valves are often left partially closed by accident. Double-check any fixture shutoffs that were recently serviced.

6. Look for Pressure Fluctuations

Does pressure rise and fall randomly? That may indicate a failing PRV (pressure regulator) or a supply inconsistency.

7. Inspect For Visible Leaks

Outdoor spigots, crawlspaces, and basements can hide small leaks that affect pressure.

Still Experiencing Low Pressure?

If you've gone through this checklist and your water pressure is still weak, a diagnostic is the safest next step.
