Common Causes of Low Water Pressure

There’s nothing more frustrating than turning on the faucet or shower—only to be met with a weak trickle. Low water pressure isn’t just inconvenient; it can also be a sign of a bigger plumbing issue.

At Affordable Plumbing, Heat & Electrical, we help Colorado Springs homeowners diagnose and fix water pressure problems quickly and affordably. Let’s take a look at the most common causes of low water pressure and what you can do about them.

🚿 1. Buildup in Pipes

Over time, mineral deposits from hard water (which is common in Colorado Springs) can build up inside your pipes. This narrows the pipe diameter and restricts water flow, leading to lower pressure throughout your home.

Solution: A professional plumber can inspect and clean your pipes—or recommend replacement if buildup is severe.

🔧 2. Partially Closed Shut-Off Valves

Sometimes, the issue is as simple as a valve that isn’t fully open. If your main water shut-off valve or water meter valve is partially closed, it can reduce water flow to your entire house.

Check this first: Ensure all shut-off valves are fully open.

🚰 3. Pressure Regulator Problems

Many homes have a pressure regulator to control incoming water pressure. If it fails or malfunctions, it can cause sudden drops (or spikes) in water pressure.

Symptoms: Low pressure at all fixtures or noticeable fluctuations in pressure.

Fix: A licensed plumber can test the regulator and replace it if needed.

🧼 4. Clogged Faucet Aerators or Showerheads

If only one fixture has low pressure, it might just be a local clog. Sediment and mineral deposits can collect in aerators or showerheads, blocking water flow.

DIY Tip: Unscrew the aerator or showerhead and soak it in vinegar overnight to dissolve buildup.

🚿 5. Leaks in Your Plumbing System

Leaks—especially hidden ones—can significantly reduce water pressure. If water is escaping from a broken pipe somewhere, there’s less available at the tap.

Warning signs: Damp walls, ceiling stains, or higher-than-usual water bills.

Action step: Call a professional plumber for leak detection and repairs.

🏢 6. Shared Water Lines or Peak Usage Times

If you live in an older neighborhood or share water lines with other homes, pressure can drop when multiple homes are using water at the same time—like early morning or evening.

What you can do: Schedule showers and laundry during off-peak hours or talk to a plumber about pressure-boosting options.

🏠 7. Corroded or Old Pipes

Galvanized steel pipes, often found in older homes, are prone to corrosion and internal rust. Over time, they restrict water flow and compromise water quality.

Solution: Repiping with copper or PEX may be the best long-term fix.
