Why Is My Water Pressure Low? Common Causes and Fixes

By Ryan Wolfe • January 3, 2025

Low water pressure can turn daily tasks—like showering or washing dishes—into frustrating chores. If you’re tired of weak water flow, don’t worry! There are several common reasons behind low water pressure, and many of them are easy to fix. Let’s dive into the top causes and solutions. Clogged Pipes or Fixtures Over time, mineral deposits and debris can build up in your pipes or faucet aerators, restricting water flow. Fix: Unscrew faucet aerators or showerheads and soak them in vinegar to break down blockages. If the problem persists, professional pipe cleaning may be necessary. Leaky Pipes Leaks reduce water pressure by allowing water to escape before reaching your faucet. Even small leaks can lead to noticeable drops in pressure. Fix: Look for signs of leaks—like damp spots or mold. If you suspect a hidden leak, it’s best to call a plumber for a thorough inspection. Pressure Regulator Issues A malfunctioning pressure regulator can lower water pressure throughout your entire home. Fix: Test the regulator by attaching a pressure gauge to an outdoor faucet. If the reading is low, the regulator may need adjusting or replacing. Municipal Water Supply Problems Sometimes, the issue isn’t inside your home but with the local water supply. Cities occasionally experience drops in pressure during peak usage hours. Fix: Contact your water provider to check for reported issues. Corroded Plumbing Older homes with galvanized steel pipes may experience internal corrosion, which restricts water flow over time. Fix: Corroded pipes may need to be replaced. Consider upgrading to copper or PEX piping for better longevity and performance. Need Help? If you’ve tried these solutions and still have low water pressure, it’s time to give us a call.
