Why Is My Water Pressure So Low? Common Causes and Fixes for Your Home

Experiencing low water pressure in your home? Learn the most common causes—from mineral buildup and pipe corrosion to faulty regulators—and how Lieber Mechanical’s plumbing experts can help restore strong, steady water flow. Schedule your professional plumbing inspection today!

If you’ve noticed your shower isn’t as strong as it used to be or your sink takes forever to fill a glass of water, you might be dealing with low water pressure. It’s one of the most common plumbing complaints homeowners face—and while it can be frustrating, it’s often a sign that something deeper is going on in your plumbing system.

At Lieber Mechanical, we’ve helped countless homeowners in the area identify and fix water pressure problems quickly and efficiently. Here’s what might be causing the issue in your home.

1. Mineral Buildup in Pipes

Over time, hard water minerals like calcium and magnesium can build up inside your pipes. This buildup narrows the pipe openings and restricts water flow, leading to low water pressure throughout the house. If your home is older or doesn’t have a water softener, this is a common culprit.

Solution: Installing a water softening system can help prevent future buildup. If your pipes are already clogged, a professional cleaning or pipe replacement may be needed.

2. Corroded Plumbing

If you live in an older home with galvanized steel pipes, corrosion could be to blame. Over time, rust and corrosion can reduce the interior diameter of your pipes and weaken the flow of water.

Solution: The best fix is to replace old plumbing with modern materials like copper or PEX piping. A licensed plumber can inspect your system and recommend the most efficient solution.

3. Faulty Pressure Regulator

Many homes have a pressure regulator that controls how much water pressure enters your plumbing system. If it fails, your home might experience sudden drops (or spikes) in pressure.

Solution: A professional plumber can test and replace your pressure regulator quickly to restore balanced pressure throughout your home.

4. Leaks in the Plumbing System

Even small leaks can reduce your home’s water pressure by allowing water to escape before it reaches your fixtures. Leaks can occur in visible places (like under sinks) or hidden areas (such as inside walls or underground).

Solution: Keep an eye out for higher water bills, damp spots, or unexplained puddles. Lieber Mechanical can perform a leak detection service to locate and repair the issue fast.

5. Municipal Water Supply Issues

Sometimes, the issue isn’t in your home at all. If your neighbors are also experiencing low water pressure, your city’s water supply or main line might be having a temporary problem.

Solution: Check with your local utility provider first. If the issue is isolated to your home, call a plumber to diagnose the internal system.
