Water Pressure Issues: Causes and Solutions

Low water pressure can make simple tasks like showering or washing dishes frustrating. While it can sometimes be a municipal issue, the problem often lies within your home's plumbing system. Understanding the common causes is the first step to restoring your water flow.

📉 Common Causes of Low Water Pressure

Several issues can lead to a sudden or gradual drop in your home's water pressure.

Closed Valves: Your main shutoff valve or water meter valve may not be fully open.
🔧
Failing Pressure Regulator: The pressure reducing valve (PRV) may be failing or need adjustment.
💧
Clogged Pipes: Mineral buildup or corrosion, especially in older galvanized pipes, can restrict water flow.
leak
Hidden Water Leaks: A leak somewhere in your system will divert water and lower overall pressure.

🔍 How to Troubleshoot the Problem

You can diagnose the source of the issue with a few simple checks.

🚿 Check Multiple Fixtures

Is the low pressure affecting only one faucet (a clogged aerator) or the entire house (a systemic issue)?

neighbour Check with Neighbors

If your neighbors are also experiencing low pressure, the problem is likely with the municipal water supply.

hot Check Hot Water Only

If only the hot water has low pressure, the issue is likely with your water heater.

read Read Your Water Meter

Turn off all water and check your meter. If it's still spinning, you have a hidden leak.

💡 Solutions for Restoring Pressure

Once you've identified the likely cause, you can take steps to fix it.

Potential Fixes

  • Open All Valves: Ensure your home's main shutoff valve and the valve at the water meter are fully open.
  • Clean Faucet Aerators: Unscrew aerators and showerheads and soak them in vinegar to remove mineral buildup.
  • Adjust the PRV: If you have a pressure reducing valve, you may be able to adjust it to increase pressure.
  • Call a Professional: For issues like clogged pipes, leaks, or a failing PRV, a professional plumber is required.

Ideal home water pressure is typically between 45 and 55 PSI. Pressure that is too high can damage appliances and pipes.
