Is there anything more frustrating than turning on your faucet or shower and getting a feeble trickle of water instead of a strong, satisfying flow? Low water pressure can be a daily nuisance, making simple tasks like washing dishes, taking a shower, or watering your plants feel like a never-ending chore. While it might be tempting to blame your local water supply, the culprit is often closer to home. Let’s look at the most common causes of low water pressure and how to determine when it’s time to call a plumber for assistance.

Common Causes of Low Water Pressure

Before you pick up the phone to call a plumber, it’s essential to understand the potential culprits behind low water pressure. By identifying the root cause, you can sometimes resolve the issue yourself or at least provide valuable information to your plumber. Here are some common causes of low water pressure:

Corroded Pipes

Over time, pipes can corrode or accumulate mineral deposits inside them. This can restrict the flow of water, leading to reduced water pressure. If you have older galvanized steel pipes, they are particularly prone to corrosion. Similarly, hard water, which contains high levels of minerals like calcium and magnesium, can cause mineral buildup in your pipes, reducing their diameter and causing a decrease in water pressure.

Pressure Regulator Issues

Most homes have a pressure regulator installed to control the incoming water pressure from the municipal supply. If this regulator is malfunctioning or set too low, it can result in decreased water pressure throughout your home. A plumber can inspect and adjust the pressure regulator to ensure it’s working correctly.

Shut-Off Valves Not Fully Open

Sometimes, the issue may be as simple as a partially closed shut-off valve. Check the valves near your plumbing fixtures and make sure they are fully open.

Water Meter Valve

The main water meter valve controls the flow of water into your home. If this valve is not fully open, it can limit the amount of water entering your plumbing system and result in low water pressure.

Clogged Plumbing Fixtures

Sometimes, the issue may not be with your plumbing system but with individual fixtures. Faucets and showerheads can become clogged with sediment and mineral deposits over time, reducing water flow. Additionally, faulty fixtures or worn-out washers and gaskets can also cause low water pressure.

Municipal Water Supply Problems

Occasionally, low water pressure may be due to issues with the municipal water supply. Factors like high demand during peak usage times, water main breaks, or maintenance work in your area can temporarily reduce water pressure. In such cases, the problem typically resolves itself once the municipal supply is back to normal.

Flow Restrictions

Certain plumbing fixtures, like water-saving showerheads and faucets, are designed to restrict water flow to conserve water. While this is environmentally friendly, it can lead to lower water pressure.

Water Heater Issues

If your water heater develops problems, it can lead to low water pressure. Sediment buildup or a malfunctioning pressure relief valve can restrict water flow. Additionally, an improperly sized water heater may struggle to meet hot water demands, resulting in lower overall water pressure. A professional plumber can diagnose the problem and perform a water heater repair to restore optimal water pressure in your home.
