What Causes Low Water Pressure?

The basics of water pressure

Water pressure refers to the force at which water flows through your pipes and out of your fixtures. It’s measured in pounds per square inch (PSI). For most homes, ideal water pressure is between 40 and 60 PSI. Anything below that range can make tasks like washing dishes, running appliances, or enjoying a proper shower frustratingly inefficient.

What causes low water pressure?

There are many reasons your water pressure might dip, and they range from minor annoyances to serious plumbing problems. Here’s a breakdown of the usual suspects:

• Sediment or Mineral Buildup: Over time, minerals like calcium and lime can accumulate inside your pipes. Unsurprisingly, this buildup restricts the flow of water.
• Leaks in the Plumbing System: Even a small leak can cause a drop in water pressure by diverting water away from its intended destination. A larger leak could lead to visible water damage or a spike in your water bill.
• Corroded Pipes: Older homes with galvanized steel pipes are especially prone to corrosion. As pipes corrode, their internal diameter shrinks and restricts water flow.
• Partially Closed or Faulty Valves: Water supply valves control the flow of water into your home. If a valve is partially closed or malfunctioning, it can reduce pressure throughout the property.
• Municipal Water Supply Issues: Sometimes, the problem isn’t inside your home at all. Maintenance work, a broken water main, or increased demand can temporarily lower pressure from the municipal supply.
• Clogged or Malfunctioning Fixtures: If the issue is localized to one fixture, the problem might be a clogged aerator or showerhead. This can be due to dirt, rust, or minerals blocked in these components.
• Pressure Regulator Problems: Some homes have a pressure regulator installed to maintain safe water pressure. If this device fails, it can cause either too much or too little pressure.

What can you do about low water pressure?

The good news is that many causes of low water pressure are fixable. Here’s how to tackle the issue:

• Clean your fixtures
• Check that valves are fully open
• Inspect for leaks
• Flush your water heater
• Call your water provider
• Consult a trained plumber
