Have a plumbing or remodeling question for the pros? Plan B Bathroom and Remodeling, your trusted experts serving Southern Maryland, are here to help!

Low water pressure can be incredibly frustrating, turning a simple shower into a trickle and making tasks like washing dishes take forever. If you're experiencing this issue in your Southern Maryland home, you're likely wondering, "What's causing this?!" At Plan B Bathroom and Remodeling, we often get this question, and the answer can involve several potential culprits. Here's a breakdown of the common causes of low water pressure in residential plumbing:

1. Issues with Your Main Water Supply:

• Public Water System Problems: Sometimes the issue isn't within your home at all. The municipal water supply in your area might be experiencing a temporary drop in pressure due to maintenance, a water main break, or high demand during peak hours. Check with your local water authority or neighbors to see if they are experiencing similar issues.
  
  
• Partially Closed Main Shut-Off Valve: Your home has a main shut-off valve, usually located near your water meter or where the water line enters your house. If this valve is partially closed, it will restrict the flow of water into your entire plumbing system. Ensure it's fully open.
  
  

2. Problems Within Your Home's Plumbing System:

• Clogged or Corroded Pipes: Over time, mineral deposits, sediment, and corrosion can build up inside your pipes, narrowing the passageway and restricting water flow. This is more common in older homes with galvanized steel or iron pipes.
  
  
• Leaks: Even small, hidden leaks can significantly reduce water pressure throughout your home. Check for damp spots on walls, ceilings, or floors, and listen for the sound of running water when no fixtures are in use.
  
  
• Faulty Pressure Regulator Valve (PRV): Many homes have a PRV, typically located near the main water shut-off valve. This valve regulates the water pressure entering your home from the main line. If the PRV is malfunctioning, it could be reducing the pressure.
  
  
• Clogged Aerators and Showerheads: Mineral deposits and debris can accumulate in the aerators of your faucets and the showerhead, restricting water flow. Try cleaning or replacing these fixtures.
  
  
• Partially Closed Fixture Shut-Off Valves: Each plumbing fixture (sinks, toilets, showers) has its own shut-off valves, usually located directly beneath or behind the fixture. Ensure these valves are fully open.
  
  

3. Appliance-Related Issues:

• Clogged Water Filters: Appliances like refrigerators with ice makers and water dispensers, as well as whole-house water filtration systems, have filters that can become clogged over time, restricting water flow and pressure. Regularly replace these filters according to the manufacturer's recommendations.
  
  
• Water Heater Issues: While less common for affecting overall house pressure, a malfunctioning water heater or a buildup of sediment in the tank can sometimes contribute to low hot water pressure.
  
  

Diagnosing the Problem:

To pinpoint the cause of your low water pressure, consider the following:

• Is the low pressure affecting all faucets and fixtures, or just some? If it's isolated to a single fixture, the problem is likely local to that fixture (e.g., a clogged aerator). If it's widespread, the issue is likely closer to the main water supply or within your main plumbing lines.
• Did the low pressure start suddenly or gradually? A sudden drop might indicate a leak or a problem with the main water supply, while a gradual decrease could suggest pipe buildup or a failing PRV.
  
  

When to Call a Professional Plumber (Like Plan B!):

While you can check for simple issues like closed shut-off valves or clogged aerators, low water pressure often requires the expertise of a licensed plumber. Contact Plan B Bathroom and Remodeling if you suspect:

• A leak in your main water line or within your walls/foundation.
• Problems with your pressure regulator valve.
• Significant pipe blockage or corrosion.
• You're unsure of the cause and want a professional diagnosis.
