What to Do When Your Water Pressure Drops Suddenly

South End Plumbing Heating & Air Expert Tips

Low water pressure in your home can be more than just a minor annoyance — it could signal a deeper plumbing issue that needs attention. Whether it’s a slow trickle from your showerhead or your faucets taking forever to fill the sink, sudden drops in water pressure shouldn’t be ignored.

At South End Plumbing Heating & Air, we help homeowners throughout Charlotte, NC diagnose and fix water pressure problems quickly and affordably. Here’s what you should know if your water pressure suddenly drops — and what steps to take next.

🚿 What Causes Sudden Low Water Pressure?

Several factors can cause a noticeable drop in water pressure in your home. Some are minor and easily fixable, while others may require professional plumbing help.

1. Clogged Aerators or Fixtures

If just one faucet or showerhead has low pressure, the issue could be as simple as a clogged aerator or mineral buildup. Charlotte’s water isn’t especially hard, but over time, small amounts of sediment can collect and restrict water flow.

Solution: Unscrew the aerator, clean it with vinegar, and test the water pressure again.

2. Partially Closed Shut-Off Valves

After plumbing work or renovations, shut-off valves near your water heater or under sinks may not be fully open. Even a small restriction can noticeably reduce flow.

Solution: Check all nearby shut-off valves to ensure they’re fully turned on.

3. Leaking or Damaged Pipes

One of the most common causes of sudden water pressure loss is a hidden leak in your plumbing system. Leaks not only reduce pressure — they can cause significant water damage over time.

Solution: Look for signs of water stains, mold, or musty smells around your home. Then call a professional for leak detection and repair.

4. Corroded Pipes

If your home in Charlotte is older, you may have galvanized steel pipes. These are prone to internal corrosion, which restricts water flow.

Solution: Corrosion requires pipe replacement. A licensed plumber can inspect your system and recommend a long-term solution like repiping.

5. Municipal Water Supply Issues

Sometimes, the problem lies outside your home. The city’s water supply system may be undergoing repairs, experiencing high demand, or temporarily reducing water flow due to line flushing or maintenance.

Solution: Ask a neighbor if they’re experiencing the same issue. If so, contact Charlotte Water or wait for service to return to normal.

🧰 How to Troubleshoot Water Pressure Problems

If you’re unsure where to start, follow these steps before calling a plumber:

Check Multiple Fixtures
Is the low pressure isolated to one faucet, or is it affecting the whole house? This can help narrow down the source of the problem.
Test Hot vs. Cold Water
If hot water has low pressure but cold is fine, the issue may stem from your water heater.
Inspect the Pressure Regulator
Some homes have a water pressure regulator near the main shut-off valve. If it’s faulty, it can cause a sharp drop in water pressure throughout the home.

🔧 When to Call a Professional Plumber

If basic troubleshooting doesn’t solve the issue, or if you suspect a leak or pipe damage, it’s time to contact a licensed plumbing professional.
