Low water pressure can disrupt showers, cleaning, and cooking. Therefore, it is important to identify the cause quickly. Fortunately, many problems that reduce pressure can be fixed without major renovations. In this post, we explain seven common causes of low water pressure and how you can address them.

1. Clogged Pipes

Firstly, clogged pipes are a leading cause of low water pressure. Because minerals, rust, and debris build up inside pipes, water flow is restricted. In older homes, galvanized pipes clog more easily. Therefore, scheduling a camera inspection helps determine if clogs are the issue. Additionally, regular maintenance flushes can prevent future buildup.

2. Faulty Pressure Regulator

Secondly, a faulty pressure regulator can cause inconsistent or low water pressure throughout the home. Because the regulator controls water force, any malfunction impacts every fixture. Therefore, if you notice pressure drops at multiple faucets, checking the regulator is wise. Additionally, replacing an old regulator restores consistent flow.

3. Leaking Pipes

Next, leaking pipes divert water away from intended fixtures. Because leaks reduce water volume, the pressure at sinks and showers drops. Small leaks often go unnoticed behind walls. Therefore, using leak detection services helps locate hidden issues. Moreover, fixing leaks promptly prevents water damage and mold growth.

4. Corroded Plumbing

Fourth, corroded plumbing restricts flow and weakens the system. Because corrosion narrows the inside diameter of pipes, water cannot pass efficiently. If you notice flakes or metallic smells in water, corrosion is likely. Therefore, repiping with copper or PEX can permanently fix the problem.

5. Municipal Supply Problems

Sometimes, municipal water issues are the real cause. Because cities perform maintenance or upgrades, temporary drops in pressure happen. Therefore, checking with your provider before calling a plumber saves time. Additionally, water main breaks can cause sudden pressure changes without warning.

6. Shared Water Lines

Sixth, shared water lines between multiple homes lower pressure during peak usage. Because everyone draws water simultaneously, demand exceeds supply. Therefore, installing a pressure booster or dedicated service line can solve the issue. Moreover, upgrading old neighborhood infrastructure helps long-term.

7. Water Meter Valve Issues

Lastly, partially closed water meter valves limit how much water enters your home. Because valves can shift during maintenance, pressure falls unexpectedly. Therefore, checking both the water meter and main shutoff valves ensures they are fully open. If valves are fine, calling a professional ensures deeper issues are addressed.
